LIFE. § SHEETS OF A NEW WORK ON PHYSIOLOGY, BY W. H. TRIPLETT, M. D., WASHINGTON, D. C., U. S. WASHINGTON, D. C.: J. F. SHEIRY, BOOK AND JOB PRINTER, 307 SEVENTH STREET, N. W. 1878. INTRODUCTORY. We invite the human intellect to fresh inspection of Itself and of the Temple in which it dwells. We speak only of Law and of Evidence. An opinion is worth nothing if it have not law for its foun- dation. Evidence is not entitled to confidence if it may not be in- spected. The mind is informed only through the senses, and comes to correct conclusions solely upon their testimony carefully taken, adjudicating matters upon law and evidence. LIFE. CHAPTER I. CARDINAL PRINCIPLES. 1st interrogatory. What is Life ? An Anatomical Basis operated by Physical Law,—this is life. 2nd interrogatory. What is the mode of the circulation of the juices which construct and sustain life’s forms? 3d interrogatory. What is Life’s Fundamental Form and Archetype ? 4th interrogatory. What are the Terms of Independent An- imal Existence ? 5th interrogatory. What is Death? Answer to interrogatory 2. The juices circulate in a vacuum, the arteries control the circulation of red blood, and as a con- sequence regulate vital phenomena. Answer to interrogatory 3. Life’s Fundamental Form and Archetype is an Ellipse, the big end up, the small end down, after S' '\ the manner of the earth’s orbit, or the / \ solar ellipses, out of which it is evolved and / \over which it is mod- eled. It stamps its I image on what it pro- duces, life’s form doing / the same The flora grow to cardiac config- \ / uration, which is an el- lipse, showing it in the \ / form of its leaflets, the shape of its shrubs, \ / trees, flowers and fruits. The higher the eleva- \ / tion the more cordiform its products. The apple vtree and apple are of high cordiform type. The fauna exhibit it in their cordiform eggs and cordiform bodies; the measure of ascent in the scale of evolution being in exact proportion to degree of conforma- tion to cardiac configuration. The body of animal life is fash- ioned over the model furnished in the central organ of the circulation Nature sets up in the first several days of the nutri- tive process, as miniature of life’s great ellipse in the stellar circulation, the matrix of life’s form. 6 I ~ Answer to interrogatory 4. The bws of independent ani- mal existence are in placental functions which have continua- tion and enlargement in the body mechanisms. Answer to interrogatory 5. Death is reversal of the Move- ment of Evolution, beginning always in the brain, with exten- sion thence to the medulla bulb, thence to the heart itself. Life disappears through the temple it first constructs, sinking below the surface in the auricles. Organic change may render the organ incapable of performing its proper labor upon the circulation, and somatic death ensues. Nevertheless there is no infraction of the law, for cardiac action continues the most persistent. The outermost works, or border-land, are the first abandoned, as they are the last constructed The intellect goes first; then respiration; then cardiac pulsation. The heart has ceased to fill up and strike against the chest-wall, but if the chest be opened it will be seen to continue its rhythmic move- ments some minutes later. Resuscitation is revival of the movement of evolution, commencing from the heart, with ex- tension to the medulla bulb, thence to the cerebral cortex. The intellect is the last to revive. Every one of these allegations rests upon an ANATOMICAL BASIS ; or has support in well-known PHYSICAL LAW; or in DIRECT PHYSIOLOGICAL EXPERIMENTA- TIONS; or in CORROBORATIVE EVIDENCE, in vast amount in MEDICAL EXPERIENCE; in addition to the weighty circumstance, that heretofore UNANSWERABLE MEDICAL PROBLEMS have ready solution; being a de- gree of circumstantial evidence sufficient in itself to make con- viction a moral certainty; BUT TAKEN ALTOGETHER, LEAVES NOT ROOM ENOUGH TO STAND AN INTERROGATION POINT UPON. Before the intellect can perform work upon the darkness which besets it on every side, it needs to have clear apprecia- tion of the tools it has to work with, and the nature of the ob- struction which stands in front of it, inhibiting further ad- vance. And it is necessary to have an enterprise clearly thought out, and a problem have formal statement upon the scientific slate, before a move be made upon the black border- land. The engineer must have suitable instruments, and firm- ness of footing; avoiding the morass of superstition; being al- ways brave and vigilant. The proper preparation is the edu- cation of the senses. The intellect can only be informed in this manner. The greater number of the five senses he can 7 bring to bear upon the labor of inspection, the more highly qualified is the individual to perform effective work, and in- form himself of the true relation of things in the environment out of which he is evolved, and of his own individuality, which occasions him so much solicitude and so much care. Would he know more of life ?—he has instruction how to proceed to work. The animal body is a corporate mechanism of many smaller mechanisms. Set that fact down upon the slate. It is the first proposition of the vital problem. The body may be resolved into pieces of complete mechanisms, inter-depend- ent. It is a composite government; it is capable of still fur- ther resolution ; it was evolved out of blood. There is writ- ten history of organization, and growth out of blood, in cm- bryological tracing. There needs to be a scheme of construc- tion and adjustment of means to the end sought to be attained. Where there is method there must be a scheme This is not all. It is a well-known fact, easy of demonstra- tion, that vital phenomena, as well as nutritive processes, are dependent upon the circulation of the blood; hence it follows as a corVellary that the manner of its generation, and the mode of its distribution, is matter of paramount inquiry; to have satisfactory answer made before Physiology may make for- ward movement into unknown territory of vital elaboration. The manner of the circulation of the blood to be made out fully; and thorough appreciation of the mechanism had pos- session of by the mind: that formal statement may be made upon the slate; how blood circulates throughout the entire body ? How it is regulated in the vascular apparatus, so that it may be turned on or turned otf a part ? Vital phenomena have explanation, in this circumstance. To put the interroga- tories tersely : How do arteries and veins manage the circu- lation ? And what great physical law has application to the vascular apparatus ? These latter interrogatories to have con- spicuous place upon the slate. The law being specialized, it will be in order to go into the inquiry how the vascular tubing perform their work, in the necessary steps to carry out the law ? To execute a law there must be power delegated to the vascular tubing of a high or- der. The time is come to set down other interrogatories upon the slate. How is an artery constructed ? What are the anatomical constituents of an artery ? Anatomical structure has definite meaning and ready interpretation given it. Mus- cular substance is Nature’s preparation for producing MOTION 8 in animal mechanisms. Nerve ganglia, and nerve wire con- necting them with muscular substance, is Nature’s method for energizing it. This is the source of all voluntary and involun- tary movement in animal mechanisms. The result is depend- ent upon the location and arrangement of the muscular sub- stance. In the straight muscles condensation and shortening take place upon a line between their points of origin and in- sertion, flexion or extension being matter of location and leverage only. If, for example, muscular substance be upon the back of the arm, when it contracts under nerve stimulus there will be extension of the forearm. On the other hand, if it be upon the front of the arm there will be flexion of the forearm, upon condensation from nerve stimulus. If mus- cular substance be disposed in circular fibres, as happens in arte- rial and intestinal tubing, its condensation means diminution of the lumen of the vessel. Before proceeding further it would be in order to return answer to these several interrogatories, as nothing can be done until proper answer be rendered. We formulate them in reg- ular order, beginning from the initial point: First, What physical law has application to the vascular ap- paratus for the circulation of blood ? Second, How do arteries and veins manage the circulation and carry out the law ? The answer to the first question is that blood circulates in a vacuum. By energizing muscular substance nature is ena- bled to form a vacuum, and by aid of atmospheric pressure which stands upon everything with great weight, she is en- abled to force the surrounding juices into the excavation until the cavity be filled. The great physical law upon which vital mechanisms have construction for the circulation of the juices is formation of vacuum areas, and the filling of the same by atmospheric pres- sure force. The auxiliary to the movement is in special mag- netic force, known as chemical affinity, of especial service in plant life. In animal forms the chief means of transportation is formation of vacuum areas, and muscular energy constring- ing the contents in the rhythmic movement of aspiration Speaking of magnetic force as auxiliary, water has strongest affinity for carbon, seeking it in the remotest branches of the tallest trees. It tears itself away from the powerful magnet of the earth to do this, supporting in its midst the soluble salts for the nutritive processes of the plant. ALL LIFE has con- 9 s traction upon WATER, the highest forms having as much as three-fourths of their gross composition in this single element. The gray substance of the brain is eighty per cent, water and five decimal over. The lower the organization the less pro- portion of water there is in it. In animal structure cartilage has less than bone, the latter less than muscle, and muscle less than brain substance. The commerce of the tissues float upon the water of the circulation. In animal life this commerce has introduction into the body, and transportation through its hid- den channels, by agency of atmospheric pressure force and formation of vacuum areas in front of it. There is no other mode to remove resistance and obviate'friction. By such agency substances have importation into the body and expul- sion from it. The lowest forms create a vacuum behind sto- mata when atmospheric pressure forces in the juice in which the microcosm swims until the cell is full. This is amoeboid movement. In the higher forms, as in the mammalian, the animal opens its mouth into water, then rarities the air in the mouth cavity by withdrawing the oral air into the lung vacuum, made by descent of the diaphragm, in simultaneous and har- monious movement with the external performance, when atmospheric air presses the fluid into the excavation or unoc- cupied area. The importation of air is accomplished in the same manner. After water or other substance is in the mouth, the buccinators and dorsum of the tongue close around it in a species of systole, and push it beyond the isthmus of the fauces, where the movement to form the vacuum area is more simple. The vermicular motion of the intestinal tubing called “peris- talsis,” constituting such vacuum areas and succeeding systoles. The infant begins it at the breast. Tightly closing its lips around the nipple, it forms the vacuum in the mouth cavity, whilst atmospheric pressure standing over the mamma ex- presses the lactic juice into the unoccupied area. Imitation of the same process is the invention of the breast-pump Cup- ping and leeching is enlarged application of the same principle as therapeutic device to relieve a part from congestion. The principle ever remains the same and cannot suffer change. There is variety in mechanical construction ; that is all. The terms never suffer change. The infant gives indication at the breast HOW IT IS TO LIVE. The law for the importation of the juices into the body is the one for their transportation through the mechanisms. Drinking is of more difficult performance in the quadruped 10 than in the man, since the former is necessitated to lift the water from the ground solely by aspiratory force, whereas in the latter the hand is made to do important service and the magnetic force of the earth (gravitation) overcome by that means. Still, after it is so raised to his lips, he would ut- terly fail in the effort to transport it to the inner side of his body but for the aid of aspiratory force in the mouth- cavity, which he must summon to his assistance. He must make a vacuum in the mouth-cavity before water can climb into it under atmospheric pressure force. He can lighten the labor of aspiration but is utterly unable to dispense with it. That he does so relieve it, let him make attempt to drink from the ground, especially if he be fat, and of impeded respiration. Being so afflicted, he has greatest difficulty in withdrawing the oral air into his lungs to form the vacuum in the mouth, since the voluminous abdominal viscera have such tight compression against the diaphragm from his weight upon them (as he lies upon his stomach) that the organ cannot force them down to make the vacuum in the lung cavity; so that when he opens his mouth into the streamlet, atmospheric pressure standing upon it accomplishes nothing for him with all its force. But his thirsty horse standing near lifts the fluid up the whole dis- tance of the long axis of his head and neck; and his fellow- companion who is of spare build and free respiration is up in a few moments having filled himself quickly; the difference between him and them being entirely due to respiratory ca- pacity with its qualifying power to form the oral vacuum. Fat men carry cups when they journey in the forrest. At each suck the diaphragm must descend else there will be no drink- ing. If arteries are not manipulated by nerves it is in order to explain the following strange proceeding, viz.: The applica- tion of ice to an inflamed part. (The manner it stops hemor- rhage is the manner it stops inflammation.) The application of external heat in pneumonia and peritonitis and other deep in- flammation. The application of a blister over the sacrum or hypogastric region in visceral disease located in the pelvic ba- sin. Why cup the loins or irritate them in renal congestion? What are you doing with these agents ? Take example of the chest region, the skin, superficial fascia, pectoral muscles, cos- tal bones, and pleural lining, are interposed between them and the lungs. Moreover, after penetrating this barrier, you come down upon the plural cavity, the lung having no connection 11 with the walls unless pleuritic invasion have had such effect upon them. It such prompt relief, as frequently happens after such procedure, be not due to impression made upon the sens- ory nerves of the part, thence reflected to the spinal medulla, and the DOUBLE ROW OF GANGLIA along the dorsal column having CONTROL OF THE DEER VASCULAR TERRITORY, (in this instance the posterior pulmonary plexus, thence to the pulmonary vascular apparatus,) it would be in order to furnish other explanation and make us intelligent upon this point. We await answer It is a matter of impor- tance. Li the chapters on the circulation of arterial and of venous blood, special nerve territory has consideration, with tabulation of numerous physiological experimentations. Spinal nerves have special vascular territory, and the circulation may at any time be influenced through them, and blood turned on or turned off a part, according to the energy of nerve stimu- lation. If the spinal medulla be destroyed up to the sixth dorsal vertebra the animal will die in twenty-four hours of brain anemia, the paralyzed abdominal apparatus holding nearly all the blood in the body. In the chapter on the circulation of the blood anatomical and physiological data in great abundance have full exhibition to confirm the statement that the entire vascular apparatus, inclusive of intestinal, venous, lymphatic, air, and arterial tubing, are composed of a vast series of tubular hearts, pos- sessing the power in great or less degree to aspirate liquids into their cavities, and to expel them again in rythmic movement. In the chapter upon the Placentia, evidence anatomical and physiological is given to prove that the intestine is only a great venous tube, and analogue to the tortuous venous sinuses un- der the placenta, but instead of blood contains chyle, out of which the villi of the independent animal make selection of nutrient constituents, turning them into the radicals of the por- tal vein (the new umbilical vein) of the independent animal, as placental villi do, from the venous sinuses underneath it. This could not always continue, and larger preparation for a larger environment had to be made in advance of the change; hence such great analogue. For the present we defer further description. We claim it to be muscular tubing, with power to fill and empty itself, in a series of cardiac territories of lim- ited extent, which actively expand and actively contract under the stimulus of their contents. This is the meaning of “peris- talsis.” 12 Muscular substance, and ganglionic nerves to energize it, are the two great factors to all the vascular apparatus for the importation and quick transportation of the juices. There is no exception. Physical law is no pent-up Utica, but has uni- versal application and extension over the entire class of animal mechanisms. By muscular force solid substances are caught by the incis- ors and cut in twain ; by muscular force is triturated between the grinders and insalivated. After this it is pushed beyond the isthmus of the fauces, where it is passed down the cesopha- gean escarpment to the dilated portion of the intestinal tube for further reduction and preparation, and by active muscular ex- pansion and contraction is passed along a complete cardiac chain, forming the intestinal tubing Such active expansions being necessary to guard the delicate epithelium, and ward off traction force and incision of hard substances from the highly organized and delicate villi, which would otherwise be una- voidable. Serious detriment would result with arrest of func- tion if intestinal contents had to force a passage by severe con- stringing movement only. There can be but one opinion upon this subject. It would be a bad plan. Nature never adopts a bad method. It is therefore not the true one—she promotes the best. Arrest of this movement is constipation; it is gang- lionic lesion Cathartics are substances which stimulate these ganglia. What remains for solution at the present stage of inquiry is : IIow are arteries constructed, and what their anatomical com- position ? The former requires consultation of embryological evolution. Arteries are made in sections of distinct pieces, and have construction and elaboration, as the heart is being built and elaborated, and finished when it is completed in simultaneous action, the separate pieces having connections made from time to time, like a lengthening train of cars, till at length the whole is complete in one harmonious line of ar- terial tubing, when blood may pass over continuous conduits. But the circumstance must be ever borne in mind that they were made independent of the heart, doing their own work of self-construction as the former was building up itself. Having such high prerogative at life’s beginning, it may well be sup- posed Nature does not intend TO TAKE AWAY THEIR INDIVIDUALITY when she links them together in a contin- uous line, to act in concert, as a file of soldiers, for the com- mon good, the whole army of hearts being under one system 13 of government, and acting with the central organ of the circu- lation. When one cardiac territory falls out, (indicated by ganglia in the muscular walls,) there is interruption of the cir- culation at that point. In other words, to use old terminolo- gy, there is “congestion” in the part The matter has full consideration in the chapter on the circulation. The anatomi- cal composition of an artery is the same as that for the heart, the modification being only in difference of arrangement and in size. But when amount of tissue in the two has full consid- eration, the gross amount of arterial structure is fully fifty times greater than the central organ. Each has three coats or tunics—an internal, smooth, non-vascular one. In the former it is called the “intima,” in the latter, the “endo-cardium.” The heart has a powerful muscular tunic, so have the arteries. The arterioles are more than half muscular substance. Lastly, the heart has a strong fibrous envelope, to limit dilatation; the arteries have their strong fibrous adventitia,to limit dilatation in their walls also. The heart has sympathetic ganglia in its muscular substance, and plexuses of nerves upon it. The ar- teries have special sympathetic ganglia in their muscular sub- stance, whilst the external wall is literally covered over with nerve plexuses. The heart has communication with the cer- ebro-spinal axis through the par vagum. The double chain of spinal ganglia of the sympathetic have each two roots of con- nection with the spinal cord; the sympathetic nerve has most intimate union with the cerebro-spinal axis It is a matter of demonstration, the entire vascular tubing is under control of sentient nerves; that they contract and expand under appro- priate stimulus. Blood is turned on or turned off a part by arterial behavior only, in response to special stimulus. The hsemic hydraulics is under control and is manipulated by the arterial tubing, through cardiac ganglia resident in their walls. Condensation of its muscular substance means anemia of the part, and if it continues over long, there will be necrosis of the bleached part, as in ergotism from spurred rye. Relax- ation, or paresis of its muscular substance is followed by con- gestion and disturbance of the circulation in the affected local- ity- Nutrition and vital phenomena have regulation by the vas- cular apparatus. The import of two most important medical terms-—anemia and hyperemia—may now he given, and true explanation rendered to a vast deal of important symptomat- ology. 14 It is a matter of great moment that the entire vascular ap- paratus, more especially the arteries and intestines, are under influence of sentient nerves of the skin. For example, the great weakness coming on in sea bathing is due to cerebral anemia, from condensation of cephalic arterial tubing and the deep vascular territory of the trunk, with consequent transfer of arterial blood to the body surface. If it go too far, syncope will be produced, so great is the alteration in hsemic hydraul- ics, with excess of blood diversion from the brain substance to the body superfice. The sudden desire to pass water, or fecal matter (if any be present in those receptacles,) is measure of amount of condensation in the intestinal tu bing or walls of the bladder, the whole being under one system of government, and connected with the skin surface through the double row of dorsal and lumbar ganglia, extending the entire length of the spinal column. An impression made over the sentient nerves of a part has immediate report made to these telegraphic sta- tions, and radiates at once over all the immediate visceral con- nexions. The common practice of relieving infantile colic by placing the little sufferer in hot water, has ready explanation. Hot baths operate by causing condensation in the deep vascular territory, including the large venous tube of the intestines and bladder, etc., the fluids having expulsion to the external sur- face, excementitious matters being driven through the sphinc- ters and blood into the skin capillaries. If it be pushed too far, syncope will result; if further than this still, death will ensue from deep bleaching of the brain substance. In this manner an animal may be bled to death without loss of one drop of blood from the vascular apparatus. On the other hand, local bleaching in vital parts may be suddenly induced by NERVINES or by TRAUMATIC INJURY. Chloroform kills by inducing, 1st, CEREBRAL ANEMIA (unconscious- ness ;) 2d, by inducing BASILAR ANEMIA, with consequent arrest of respiration. Syncope is basilar anemia of short du- ration, the heart not filling up and striking the chest wall as usual, yet it still continues its rhythmic movements; and if the left chest be opened, they may be seen to continue for some minutes later. It is the same case in death from a blow or gunshot injury to the brain. Heath always occurs from BASI- LAR ANEMIA This subject has full consideration in the chapter upon the functions of the sympathetic nerve, with abundant physiological experimentations to confirm the state- 15 ment, “that death is always from basilar anemia,” the heart being the last organ to suspend its movements. When ganglionic lesion takes place in an artery the result is congestion. The essential factor being the circular muscu- lar substance is not energized by appellate nerve ganglia, with arrest of active expansion and contraction Cure is effected by stimulation of the ganglia. Application of cold or other suitable stimulant to the nerve-arc supplying the affected walls is preferable to all other methods when direct application is impossible. Medicated blood has arrest in a paralyzed artery and stimulates it, when it condenses itself. It passes too rap- idly over sound arteries to affect them. In respect to other matter. THE BLOOD and ALL THE JUICES CIRCULATE IN A VACUUM. The advantage is too apparent to require argument to show its great utility. It may he mentioned cursorily that it away with the necessity of a mighty central cardiac force, as now obtains, a fraction of such force being all that is necessary to the per- formance of the circulation. The arteries and arterioles aspi- rate blood by active dilatation. The corpuscles are saved the rudeness of distension force upon the walls of the arteries to make a roadway for them into the tissues, not to mention the circumstance of enormous atmospheric pressure to be over- come by the central engine, since it is all outside the arteries, upon the base of the pyramid, and would have to be overcome before blood could run under it. The corpuscles would go to pieces at once if such thing could be attempted. Nature does not place such burden upon the heart; on the contrary, each artery and arteriole lifts up the air that stands upon itself, acting simultaneously and in universal accord, as a vast army of well- trained soldiery They move in unison for the common good. The blood therefore performs no rude labor and sustains no shock beyond what is necessary to lift it through a vacuum. It has ceased to be impossible to give explanation of con- tinuance of arterial circulation, after an aneurismal mountain has risen up in the road-way of the blood, especially in in • stances of enormous thoracic aneurism. In such condition the muscular substance of the heart is frequently atrophied. Ac- cording to the law of muscular development, this is the oppo- site of what should happen, predicated upon the statement that the labor of carrying on the circulation is performed by the heart Hypertrophy of that organ means imperfection of its valves and measure of such organic change. 16 Symptomatology has fresh interpretation. The condition indicated by “shock,” the most difficult term in medicine to define, (and never has been,) is rendered transparent under the white light of physical law. It is a sudden condensation of arterial tubing through encephalic territory. MENTAL MO- TION or traumatic injury is exciting cause. It is DEEP BLEACHING OF THE BRAIN SUBSTANCE FROM ARREST OF ARTERIAL FLOW from quick diminution of the lumen of the vessels. A powerful systole has been ex- cited in the arterial walls and blood inhibited from the natu- ral channels. The internal carotids, for example, have not near their size, their walls being so energetically condensed un- der stimulation of nerve wires focused upon them through the carotid plexuses. Some females have very flexible and excitable carotids, condensing them on the slightest occasion. A sight of blood will make them faint. Mental motion is ex- cessive in them from this cause. They are very emotional, because arterial blood is subject to irregular distribution from lack of uniformity in arterial behavior, and are often “giddy” from sudden brain anemia. The generative apparatus is most potential cause of vascular disturbance in them, robbing the cortical portions of the cerebrum, by sudden springing open of arterial mains in the pelvic organs and abdominal viscera. Women who grow “nervous” have need TO CONDENSE THIS DILATED VASCULAR APPARATUS and SEND MORE BLOOD TO THE BRAIN. Sponging the body surface with cold salt water, especially the dorsal region, will send the blood back into its channels. THE DOUBLE ROW OF DORSAL and LUMBAR GANGLIA ARE CENTRES OF NERVE ARCS TO ALL THIS APPARATUS—ONE END BEING UPON THE SKIN, THE OTHER UPON THE VASCULAR WALLS. An impression made upon the skin surface has immediate reflection upon the arterial, venous and intestinal territories. If cold water is not success- ful, let warm water and salt be substituted. That hundred-headed hydra “Hysteria” may have intelli- gent inspection, and be looked through and through. Hemic hydraulics is tampered with, and blood has irregular distribu- tion in consequence. Convulsion is the result of over-vascu- larity of the base of the brain and spinal cord. Coma is Anemia of the Cerebral Cortex. Delirium is the product of Irregular Vascularity of the Cerebral Cortex. The hard wiry pulse of extensive peritonitis has ready ex- 17 planation. Nearly all the blood in the systemic circulation is in the abdominal organs, and in order to keep the brain sup- plied the arterial tubing condenses itself upon the remnant to propel it along, and give them control of what is left. The arteries become hard as wire in consequence of EXTREME DEGREE OF CONDENSATION, the arterial lumen shrink- ing in a ratio with the contained current. The whole vascu- lar apparatus (outside of the abdomen WHICH IS PAR- ALYZED) is under tribute to the brain. The red corpuscles are sent to it as long as there are any to send. The RIGOR MORTIS irons out everything; the last systole of the ventri- cle (now relaxed;) the last systole of the arterial tubing (now also relaxed;) the wiry radials are gone with the last systole of the arterioles, and nothing is left in their open lumen of what the arteries had been during life; not so much as a vestige of the tragic end remaining. The Left Ventricle is EMPTY; the Arteries are EMPTY. Is it Coincidence only, or corres- pondence of function ? Do not arteries contract upon blood as well as the heart ? What is the hindrance ? Hindrance— the word is in Medical Imagination, not in anatomical con- struction, for this looks all the other way. Take up the slate and write this upon it—THE AUTONO- MY OP ARTERIES. THE MODE OP MOTION IN THE TRUNK is the same as that for the vascular walls. It is susceptible of demonstra- tion that it expands and contracts rhythmically, having an in- terval of rest, after the manner of cardiac movement. Respiration is a circulation and pulsation of the trunk of an- imal life THE PLACENTAL SOUFFLE OF THE INDEPENDENT ANI- MAL—the number of such movements or pulsations being sixteen per minute. It is the number of miles life travels per minute by the axial movement of the earth. It is a matter of demonstration that increase of this move- ment is the essential factor of fever. The thermometer test ap- plied before and after vigorous lung performance in a set of vocalists is an experimentum crucis. After an hour’s exercise increase of temperature is in exact proportion to lung exertion and lung capacity. It is a matter of surpassing interest that respiratory perform- ance may have influence from external nerves. The inter- costals are motor and sensory, administering to all the external walls, and when irritated by scald, or specific poison of the 18 exanthemata, hurry respiratory movement by reflex action upon the spinal medulla, with extension to the phrenics and pneumogastrics. The danger is in proportion to extent of sur- face involved and duration of the irritation. Death from scald and death from small-pox or scarlet fever is the same vital performance, and is the result of excessive blood temperature, causing great restlessness, delirium, coma, and finally suspension of respiration. To revive respiratory movement the head should be lowered. To re-awaken it the trunk should be inverted and rhythmical compression made around the walls, with powerful stimulation of the skin-surface, including castigation, the object being to facilitate arterial flow to the medulla and medulla bulb, the vascular ganglionic centres having impression made upon them over nerve arcs terminating upon the skin. The pulmonary organs are for importation of oxygen. In- crease of respiratory movement means increase of blood tem- perature (if it be not physiological compensation for diminished lung area.) The formula is simple for the regulation of blood temperature. Regulate Respiration. To reduce fever, In- crease the Surface Evaporation. Sponging the naked body (in extreme cases) with tepid wa- ter, with free ventilation, will accomplish speedy reduction of body temperature. Fanning expedites surface evaporation. ’Tis Nature’s method for absorption of heat. Create currents of air over the moist body from tepid bathing. To reduce respiratory movement Induce Sleep by full doses of chloral, when blood temperature will admit narcosis. Res- piration falls during sleep to almost normal rate of speed; tem- perature falls in consequence. Surface evaporation to have regulation by the thermometer. Sleep to follow reduction of temperature. Increase of respiratory movement will be per- sistent in degree to duration of exciting cause. Invasion of low organisms speedily subsides—they soon perish. In pro- tracted fever local lesions, set up by the microcosm, keep up respiratory movement; local lesion to have regulation through the vascular apparatus by reflex stimulation through nerve arcs terminating upon the external surface. The chief danger in fever is excessive blood temperature. The office of therapeu- sis, to regulate temperature and respiratory movement. Local irritation hurries respiratory movement. Gastric fever results from irritation of the par vagum and trisplanchnic nerves, re- flected upon the spinal medulla and medulla bulb. CHAPTER II. life’s fundamental form and archetype. All substances have FORM; it is visible evidence of OR- DER. Life lias appropriate form in harmony with universal behavior. The viscera in animal forms have definite shape, and perpetuity throughout all time, in all portions of the globe. The law applies to the body or trunk in which they have sus- pension ; otherwise definite forms have embrace in an indefi- nite form. Such proposition is remarkable and monstrous. THERE IS DEFI- 11 18 Ih HARM°- / \ NY WITH UNI- HITE SHAPE TO / \ VEKSAL ORDER, THE BODY OF I AND PUBLISHED \ / THOUGIiOUT THE PLANT AND ANI- \ / \ / FLORA AND THE MAL LIFE. FAUNA. LIFE’S FUNDAMENTAL FORM AND ARCHETYPE IS AN OVOID. Polar force organizes matter into form by crystallization. On a cold morning it is seen in its lowest type in tire beautiful archetypal miniatures cast upon window-plates, of frost-ferns, frost-leaflets, arbor-vitas, etc., from a moist atmosphere of a ‘‘living room.” These beautiful archetypes of plant life are resolvable into minute atoms. Matter crystallizes into a sphere, as the lowest expression of life’s form. It is earliest effort to organize life into vital gov- ernment. The earth is globular from magnetic force; so is the cryptogamic cell from prevalence of the same law. From this point life’s form grows up into an ELLIPSE, making progres- sive stages of ascent, and leaving record of progress in in com- pleted forms. The ellipse is the line of momentum of planet- ary spheres—the pathway of the stellar circulation. The im- petus of this momentum is pulsated through matter, which be- ing free to move under guidance, under all-pervading magnetic 20 force, swings into the line of march with universal order and discipline. All moving bodies circumscribe elliptical config- uration as the foot-path of their momentum. It is the mode of motion of the solar circulation. The large end of the earth’s orbit is up, the small end down. The flora hold up this configuration in their highest products. The more advanced the growth, the more elliptical or cordi- form the fruit, the leaflets, and the tree itself. The apple tree is a beautiful example. It is the highest product of the flora. Its broad base and cone-like apex has renewal in its cordiform leaflets, whilst the highest product of the tree, the apple itself, is of high archetypal form; and its very seeds have growth in this direction, as indicated in their wide upper end tapering to conical apex below. It is true of all the higher fruits—the cherry, the peach, apri- cot, plumb, strawberry, etc., etc., etc. The rosebud is highest flower, whilst its broad base, with gently sloping sides to form the beautiful conical apex, is min- iature of the great ellipse out of which it is evolved and over which it has such faithful mould. A tree is of rosebud shape, whilst a forest is vast bouquet of rosebuds. As example of persistence of ovoidal type in the fauna, do- mestic fowls may be taken as ready to our hand. Look from the rosebud to the egg of the hen. Is their very close resem- blance in configuration accidental ? Are not all rosebuds ovoidal, and all high fowl and all their eggs of rosebud shape ? The partridge is a very high bird. Its eggs are of rosebud con- figuration. In scarcely more time than one revolution of the earth upon its axis after commencement of incubation, if the egg be opened and the yolk inspected, another smaller ellipse may be seen, a miniature of the egg in which it is born. The heart is centre of an ovoidal body yet in embryo; but, when complete, and ready to break its shell, will be still higher ani- mal form. The prominent breast and tapering hinder parts is maintenance of cordiform configuration—a nest of three eggs, before the marble temple be broken and the chick es- cape. Take the dog, as example of the quadruped. Its head is ovoidal. After removal of the head and extremities, inclu- sive of all the hip muscles down to the iliac bones, (since these have reference entirely to the crural appendage,) the remain- der will be cordiform, or a broad fore part and a conical hinder part. The head of the horse is ovoidal; so his eyes. The body is of high archetypal form. One. need only direct atten- 21 tion to the quadruped in confirmation of all-pervading law. They are all cordiform. Man is consummation of cardiac growth, his body being a perfect heart. After similar removal of the extremities and ovoidal head, with the rosebud eyes on the stamen of the optic nerve, what remains is clear outline of the heart in his bosom, the little prototype Nature sets up in the centre of the blood circulation in the early hours of foetal elaboration. After for- mulation of the terms of independent animal existence, it will he in order to regard the circumstances in detail of Anatomi- cal Construction and Mode of Motion, in the body of animal life and its prototype. How do they agree? Seeing the persistence of cardiac form in the flora and fauna, it is a matter of great interest to discover the connecting links in the chain of ascent from vegetable to animal forms. It may be done quite readily. In terrestrial environment they exist in the hollow worms, which subsequently become insects in great variety, representing different stages of cardiac growth. They are all ellipsoidal. In water environment it is still the same —variety being degree and measure of development only. Fish configuration is ellipsoidal. Ocean shell have similar contour. The Mpadites Umbonatus and CONCII is beautiful carnation rosebud wrought in living marble. Nature perpetuates her image in sea and land upon life’s form and on the very marble in which it may encase itself or erect within the temple. Skeletons are ellipsoidal. Examine the diagram of a trans- verse section of the human body above the heart. Is not the general outline that of an apple? The spinous process is stem —the breast-bone is representation of the lower part or blos- som. The heart in its capsule is the seed in its envelope and origin of the tree, the source of all growth. The body is built up out of it and over it. It resembles a rosebud hanging by vascular rootlets. Territorial acquisition is in cephalic and pedal extremities, elaborating them now more rapidly, now more slowly, accord- ing to environment and means of doing so. The lumbricords are first stage of cardiac growth. They arc tubular hearts, having circular and longitudinal muscular sub- substance, with which they contract and elongate their bodies, or expand their hollow cavities to form a vacuum, and aspirate themselves full of juice, living independent of every other ap- purtenance till the time of metamorphosis—a tubular heart, 22 feeding itself and sustaining existence by itself. The “grab” is yet higher growth, almost ovoidal or cordiform. When it contracts its longitudinal fibres it is cordiform. The body of the butterfly, of which it becomes the chrysalis, is still higher form, whilst its egg is later growth toward cardiac configura- tion. The chrysalis itself is ovoidal. The body of a fly is cordiform. It is perfect in the humble bee. The head of either is complete configuration of the great archetype. The fresh water frog is example of speed of elaboration. Beginning with an egg, it journeys by rapid metamorphosis till it can set up almost human-like, and the pedestals with their five terminal digits before and behind, the abdominal breathing, erect head, and great conscious eyes, present a pic- ture remarkably near to what is accomplished in uterine gesta- tion in the human species in two hundred and eight days, the difference of time being due to the slow evolution of brain sub- stance It is the slowest evolved, and delays gestation. In water environment, cardiac evolution has many phases, different degrees of growth being observable. The leech is a water lumbricord, and can aspirate quite vigorously. If one seek for connecting links they may be found in count- less numbers. The “Medusa” is ovoidal or cordiform—a large heart swim- ming by itself and feeding on the juices of the sea. They swarm in tide-water. The scale of cardiac ascent, from the simplest to the highest forms of animal existence, in sea or land, is quite long indeed. The walrus and the whale in the former, man and the elephant in the latter, are consummation of the highest form possible to the environment. And in the pregnant woman there is miniature of it all in embryological elaboration of the ovoidal embryo ; with the ovoidal heart in its midst, as its archetypal form, the ovoidal uterus, and lastly, the ovoidal ventricle in the abdomen itself, the base at the diaphragm, the apex in the pelvic excavation; a nest of four eggs instead of three, as in the case of the chick within the egg. Most wonderful of all, the record of the jour- ney is kept in embryological tracings, beginning with the cell and progressing to conclusion. 23 EVOLUTION. Before taking up the matter of the terms of independent animal existence, it/ is our duty, as also an impulse of our mind, to follow Evolution to its present terminus. Sci- ence would account for all forms of growth and all vital phe- nomena through operation of great physical laws. EVOLUTION IS TRUE.' For confirmation of the state- ment let the intellect look upon its environment—then upon the temple in which it dwells—then upon its own behavior— and from that standpoint of observation regard stellar space attentively. Man is what he is because he is where he is. He is organized out of matter which is rocked in the cradle of the spheres. He is evolved within the environment of the stellar mechanism and participating in all its movements. He is travelling at vast rate of speed, the momentum is enormous. That attention is called to the circumstance will the ra- tional mind contend for one moment that it is not affected by the tremendous momentum? Will it deny that a vast moving mechanism containing a small one has no effect upon the lat- ter? It cannot do so and retain its self-respect, the highest loyalty in the universe and most just homage to virtue. It is not sufficiently informed, else some hidden motive in the mo- rass of prejudice and superstition swerves it from the lofty path of knowledge, to follow the ignis fatuus of dark tradition into a hopeless past. Whether it do so or no is matter for itself. This is a law that will live regardless of his behavior—that which rides upon a mechanism shares its momentum. From want of experience (his attention not having been di- rected to it) is he inclined to put in objection? Let him pro- pose to jump from a railroad train at fast rate of speed—sixty miles an hour—would any one follow the suicide? If it is ir- rational to make such jump, it follows as a necessary corollary it is equally irrational to make remark that momentum is a trivial circumstance. Take the slate and write this interroga- tory upon it—WHERE AM I? Science makes answer— You are upon a planet in the heliocentric system, riding at a vast rate of speed. The earth is twenty-fi ve thousand miles in circumference. This entire journey is accomplished in twenty- four hours, else there would not be alternation of day and night. At a given point upon the globe Life’s Form travels 1,000 miles an hour, 16| miles a minute. At such rate of speed matter takes the shape of a sphere under magnetic force which holds it fast. 24 This is not all; there remains the still greater momentum of the pathway of the earth’s orbit for consideration. It makes an annual revolution around the sun. The enormous distance and necessary rate of speed to traverse the millions of miles through space startle the intellect. The earth has a radius of 8,000 miles. At a given point Life’s Form is at the end of the radius of a vast wheel of that extent, revolving at the rate of one thousand miles per hour, and moving over an ellipse perpendicular to the radius at still faster rate of speed. It is a spiral motion. Life’s form is propelled through a screw at enormous rate of speed. Is it a matter of wonder there are whirlwinds when atmospheric conditions are suitable? Take smaller example. If a man place himself in the me- chanism of a mill he is lost, for its momentum is so great that traction force will tear him limb from limb, and further reduce the shapeless mass into a bloody fluid. Physical law pulverizes him into a juice. Man is horn within the solar mechanism, a motion within a motion. What is the result? Let him look into stellar space attentively, then into himself and into his life. Look at the shape of his heart The central organ of the circulation holds up ellipsoidal con- figuration. Look from it to stellar space for interpretation of elliptic form. There is other information. There are seven pencils of light; are they accidental? There are a number of atmospheric envelopes of volatilized metals around the sun, the source of these rays. This matter has extension : There are seven cortical layers to the earth, seven cortical layers to vegetable forms in each annual ring, seven cortical layers to animal forms with extension all through the mechanism; sev- en layers to dermic follicles; seven cortical layers to the mus- cular envelope of the body; seven cortical layers to the heart; seven to the stomach, seven to the bladder, seven to the womb and EVERY HOLLOW ORGAN. The matter does not rest here : Vital phenomena are PRO- DUCT OF PHYSICAL CONSTRUCTION—a spring bow- ing out of the organic form. Vital performance cannot rise higher than its source, and a mechanism may be known BY ITS DEEDS. Man performs great or little things in propor- tion to cerebral development; lie cannot exceed it. This is not all, for he is in the works of a tremendous mechanism, whirled through space at enormous rate of speed, and THROB- BING PLANETARY MOTION through mental movement. 25 He is part and parcel of ALL THERE IS, and miniature of it all. The seven cortical layers which pervade his organic form, shadow themselves in the grouping of layers of seven days to form a week, his earliest notation of time, whilst pro- gress in elaboration enabled him at last by terrestrial meas- urement and terrestrial movement to measure time by a rising- scale of consciousness, of the line of momentum of the vast mechanism, to record time by seconds, minutes, hours, days, weeks, months, years-—the month having reference to lunar movement, the remainder to terrestrial behavior. The axial movement, with a succession of day and night, produce cor- responding effects upon him, represented in sleeping and waking. Animal life subsides in darkness. His forms of government are perpetuation of the rhythmic movement in which he is swept along, showing increasing con- formity the higher the scale of ascent. Central solar force has representation in the organic law or constitution of gov- ernment, with impersonation of the same in the chief presiding officer, or Magistrate, or King, as the case may be. The seven cabinet officers are persistence of the seven cortical layers; the seven chief justices is further expression of the mo- mentum of this organic force. The relegation of social misadjustment to twelve individuals in a jury has vast anal- ogue in the conservation of the planetary movement through influence of the Zodiac. The rule of arbitration in the selec- tion of three men is evolved out of the potential law of the universe. Three forces dominate all there is. Republican form of government would seem to be the highest type, since life’s highest form is left free to move through its own ellipse without prejudice. Nevertheless, monarchical government shall be needed for considerable time ere sufficient numbers will have been entitled to hold the reins by higher evolution. A con- stitutional monarchy is high order of government. In his very diseases man exhibits further conformity to all- pervading physical law. The seventh day recurrence of ague after subsidence of quotidian. The seventh day recurrence, else exacerbation, of remittent fever. Fever continues in mul- tiples of seven. The 7, 14 or 21 days of typhoid fever arc cases in point. Not to continue the matter further at present, we would respectfully commend it to scientists, more particu- larly to students of astronomy, suggesting that life’s ellipse, especially that of the circulation of the blood, have careful in- spection, since the child of space needs to sustain resemblance 26 to the mother that gives it birth and supports it in its little circle of activities. Whence all the order and cohesion of government, the vis- ible evidence of all-pervading law, holding lowest species of animal life together, in harmony, having highest definition in man, if it be not momentum of the vast mechanism in which life’s form dwells, transmitted over wires that regulate its movements ? There is such a thing as MOTION UNDERSTANDING ITSELF. Life is conscious movement pervading a mechan- ism. Man elects his food, thrilling with the sensations occa- occasioned by it when passing his lips. Nor does it end here, for he rolls the sweet morsel in his mouth; he is happy with the sensations it provokes. He does even more than this ; he looks into his own mechanism, watching its motion, even his own thoughts. He has inspiration as product of high mo- mentum of thought. He is coming to an understanding with himself, knowing a vast deal more than he did how the matter stands between him and Nature, looking into stellar space fearlessly, full of unspeakable affection. Passing allusion is made to the wonderful corpuscles swim- ming on the waters of the circulation over the circuit of the blood, and comparison drawn to stellar circulation around the great ellipses in the heavens, whilst man, a miniature of it all, rides through space on something larger than a corpuscle. Solar heat is the cardiac force to the blood circulation by energizing muscular substance in the walls of the vascular ap- paratus. If animal life be miniature of the heliocentric system, as is apparent, the cardiac force to the stellar circulation is also so- lar heat, gravitation remaining as other name for all-pervading magnetic force. Gravitation is name for other thing than it is. It is misno- mer for Magnetic Force, otherwise it is without place in the solar system, is isolated and alone in a universe of affection, opposing everything, appropriating everything—Enormous— Unnatural—Solitary—Monstrous—Selfish—gulping the uni- verse down its prodigious gullet. It served useful purpose (early forms ever do) to give place to better growth and high- er knowledge of dominant potentialities of the stellar circula- tion. It was far-reaching thought of a great intellect, dispos- ing of the difficulty of planetary space for that time. Intel- lectual night is yielding under solar force. Gravitation is pass- 27 mg away upon its clouds. Gravitation needs reconstruction and fresh interpretation. There is misadjustment here. The earth is a great magnet. Everything terrestrial moves toward it when resistance is taken off; but there is special magnetic force in its component parts which cause them to assume close and intimate relation, called chemical affinity. When a tree is cut through, magnetic force pulls it speedily to the ground, where special magnetic force dissolves it, the air greatly assisting in the work, whilst water exports its alkaline earths and minerals. Finally it is resolved back into original elements. Water is the great solvent and organizer of the earth, going down into innermost depths to oxydize the metals and to dissolve them, after facilitating certain combinations in the formation of the numerous salts. What is left after these affinities have been satisfied serves as a means of transporta- tion to this hidden commerce, bringing it to the external world for the construction of plant life and animal forms. The work is going on all the time. Water that escapes at the foot of a mountain is the juice of the mountain, and that which escapes from the earth is the juice of the earth It is a most potential organizer. At the present time the Burning Spring, at Niag- ara Falls, is more luminous than ever before in the memory of the present generation. It is Sulphuretted Hydrogen Gas. The explanation is simple. The season has been an unprece - dented rainy one. Water has penetrated the rocky strata deeper than usual, and in larger quantity. Oxygen comes across a stronger affinity than it has in Hydrogen, and marries at once some powerful metal, whilst Hydrogen weds with sul- phur, becoming a luminous gas. Nature looks upward through the affections, climbing higher and higher, ever moving on- ward and upward, till life’s highest form be reached. There is no such thing as “inorganic chemistrv.” It is all organic, the difference being only one of degree. TIIEBE IS NO CONFLICT IN NATURE. There is commotion of elements falling into line to form closer union; there is co-operation and concert of action, and formation of higher products. Di- vorcements take place to effect higher and better union. Water, air and earth have construction into plant life by agency of solar force. Trees grow to a prodigious height—in California as much as 340 feet. In all that labor of construc- tion there is no conflict. Water transports the salts it gener- ates in the earth into the capillary spaces of the tree, drawn onward and upward by the powerful affinity water has for 28 carbon, the chief constituent of the tree. It hunts up carbon eagerly. In a vacuum it will rush up through the interstices of sugar with great rapidity. When the tree is cut through it falls upon the bosom that gave it birth and nourished it.' No conflict anywhere. On the contrary, there is mutual love and undying affinity everywhere. Take other example. Water falling upon the Rocky Moun- tain chain perforates to deep recesses in its sides, and, after saturation of the earth, making numerous details for the labor of organization, what is left escapes at the foot of the chain and becomes A WANDERER, going oceanward. It satisfies the affinities in the earth; the remainder starts out on a pilgrim- age. Some of the water of the Mississippi river wanders nearly 2,000 miles before it reaches the Gulf of Mexico ; even then it wanders onward to the ocean, and belts the globe itself. Where is Central Force, that it does not sit heavily upon it, and stop it in all this journey ? It moves over hill and plane —on, and on—ever onward—always moving—moving. It never stops. Where is Gravitation force, that the roaming vagabond may undergo arrest, and have estoppel of this un- ceasing marching—marching—marching? Follow it to the sea-shore; no rest-—no quiet subsidence and gentle submission to Central Force, but an unceasing, never-ending movement of the waters breaking upon the beach, now more rapidly, now more slowly, under Magnetic force emanating from the lunar orb. Study the history of the river. Is it not torn from the bosom of the ocean by solar force through vast surface evaporation, and the clouds driven landward by the same power, partly through magnetic force of the earth itself? What is left unprovided for in the earth seeks speedy return to the great magnet from which it had been removed some days and weeks previously, big end forward in this great flu- ent magnetic needle. It is the law of the magnetic needle. If a mountain spring up in the roadway it will tear it down in frantic efforts to get back home. Harper’s Ferry is ready witness, as also the Natural Bridge, in the Blue Ridge chain. The Whirlpool below Niagara Falls is eloquent witness that water will hew out a channel through the hardest stone, in or- der to make more expeditious journey to the great Magnet from which it had suffered temporary removal. At this point it abandoned an old road-bed of 17 miles in length for a new one of only 11 miles, in a quite different direction. If the metals are slow and tardy of solution, water runs over and 29 around the side of the mountain at tirst but the work of mining and excavating never ceases till more expeditious roadway is complete. Nothing is lost; out of the hard resisting moun- tain the soft seed-bed of the river deltas is formed. This is not all that water performs. Life’s form which comes up out of the earth—life’s forms everywhere are constructed upon water. Three-fourths water are the terms for highest products. LIFE HEARS ITS TEMPLES UPON A SEA. Important circumstances concerning animal life have ready explanation given them, for animal life is under magnetic force. Gravitation cannot be shown to exist; magnetic force may at any time. Why is it such difficult matter to walk? IT IS THE MO- TION OF A SMALL MAGNET OVER A GREAT ONE. The magnetic attracton of the earth is enormous, and but for OUTSIDE POWER OF SOLAR FORCE there would not be motion upon the earth. If blood temperature should fall but only one degree from 98-J to 97|, man cannot walk; if one degree below this he perishes. The essential factor of his movements is Solar Heat. Mental motion has similar arrest. What it evolves flows out of the same inexhaustible source, and when man is dead solar force re-arranges his elements. Not a temple in the earth, not so much as a stone is built in the absence of this all-pervading power. All rain would cease and air be still as death. Instinct is magnetic force. The brain and spinal cord constitute a great magnetic nee- dle, supported on movable stilts. For illustration, let a dog, cat, or pig suffer removal from home to a considerable distance. Notice the result. The needle gets up at once on movable stilts, straightens out, whirls round to the proper adjustment, and WALKS OFF to the METALS OUT OF WHICH IT HAD BEEN EVOLVED, nor pauses in the journey till it reaches home. It will go no further than home, whatever may have happened in its absence to him or his. In man the needle stands straight up. IT IIAS LOST THE POWER OF ADJUSTING ITSELF. In consequence he hesitates to send his ten-year-old son away from home; and if himself lose memory, he is lost at a slight remove only, nev- ertheless he has the strongest local attachments. He gains in other respects. Set down two more propositions. 1st. The moon has great influence upon oceanic water, caus- ing the vast movement of “the tides.” 30 2d. Life’s Form is three-fourths water. One may not dispute either of these propositions if he would have his opinion respected. Corollary—the water in life’s form is oceanic water, and af- fected in degree with the larger body. It is common belief in rural districts that sleeping with the face exposed under a full moon causes it to he swollen in the morning—dropsical. It is foolish to contend that water in the ocean may be dominated by the moon, but that upon the shore in life’s form is not af- fected. Nor does the matter stop abruptly with the lunar in- fluence, for there are constellations in the heavens holding striking resemblance to forms of animal life and plant life. For a long period of time men have been speaking of the fol- lowing constellations : Leo, Cancer, Gemini, Taurus, Aries, Pisces, Aquarius, Capricornus, Sagittarius, Scorpio, Libra, Virgo. May it be reasonably doubted that other planetary and stellar influence than the moon is moving the chess represent- ed in particles of matter upon the tables of the earth? Is water only a trifling matter, to be rolled from continent to continent as mere pastime of the moon, or is it quite as respectable as other matter of the earth ? If water ebbs and flows in oceanic basins, it ebbs and flows in Life’s Form as well, though small it is, escaping notice in consequence. Since water is under influence of the moon, may not similar influence of the stellar constellations arrange matter into shapes similar to their own? Being a less perceptible movement of matter than the vast rolling tides, yet moving nevertheless though all unconsciously to human knowledge. Impossible, say you? I would not use that term so often. It is not more incredible than for two men to hold conversation upon opposite sides of the earth, directing each other what to do for him where he is standing. This is of hourly occurrence through electric currents. Agriculturists have their signs for planting; carpenters for cutting timber they wish to use. I would not laugh at them, since they are dealing with nature, and you with your imagination only. The little stars which constitute Life’s Form are beyond reasonable doubt affected by the larger bodies moving near them. Water rolls in huge waves under lunar force. May there not be mo- tion taking place within this motion, and matter arranging itself in form of a crab by potentiality emanating from the stellar constellation of that shape ? The temple of life is built with minute stars drawn into place by magnetic force pertain- ing to the vast stellar circulation. Is.it longer matter of won- 31 der why yon gaze so tenderly into the firmament? The earth is the womb—the firmament is the body of your mother. Life embraces every motion and form of evolution, and since there is archetypal form to the body, there needs to he archetypal form to thought itself. There is such archetypal form to thought furnished in the SUPREME INTELLI- GENCE. There is matter of much import concerning man which we may not pass over in silence without doing violence to our judgment of things. Suppression is not the order of Nature; on the contrary, evolution is the eternal method. MAN IS A GROWTH. This much may he admitted without harm to anything but tradition. Much of that has al- ready been discarded without hurt. TO THEOLOGIANS. Gentlemen ! We have not aught to say against Religion ; on the contrary, believe conviction in the existence of a Su- preme Intelligence to he the primordial feeling in human life, far exceeding any other in the mind of man. This is not what men struggle against, but with the varied systems of the- ology which have been evolved at intervals, and are full of error and preposterous assumption—being no less than that they were special communications and personal interviews with the August Power of the Universe. To probe this matter a little begin at the cardinal point of inspection for the higher races—the Hebrew Bible. Take the slate and write down two propositions, viz ; 1st. Man is of God, and made by His own hand. 2d. The Holy Bible is Divine. Interrogatory: Which of these two editions of the God- Head is the elder? There is only one opinion between us. Set down two more propositions. 1st. Science says man is three-fourths water and one-fourth made up of Carbon, Nitrogen, Lime, Phosphorus, Iron, Soda, Magnesia, and traces of several other minerals. A 2d. The Hebrew Bible says man was made of clay and the dust of the earth. 32 Interrogatory: Which of these two statements is correct ? There is much clay where Moses wandered; moreover, he had not the remotest idea that man is three-fourths water, else he never would have committed so grave an error in HIS Genesis. Set down two more propositions. 1st. God made the Heavens and the Earth, and all there is, in six days. 2d. Science says, the testimony in the Geological strata es- tablishes gradual evolution of the earth’s surface, occupying millions of years in the labor of construction. Which of these two statements is true? There is no occasion to extend the matter. Wrong in the cardinal points, the matter of detail is of seconday importance. Moreover, testimony received from unreliable witness is at election of qualifying circumstances only. Your trouble lias ever been from attempt to enforce unqualified belief, and cre- ate implicit confidence in the truth of every statement of the Hebrew chronicles, emphasizing every word and letter upon the ever-growing human mind, threatening it with damnation if it showed resistance. Ah! ’tis a long, sad tale; pitiful, too pitiful, too horrible, too agonizing, too monstrous to recount upon a summer morning in the sweet sunshine. It was the sad havoc of delusion and monomania, from excessive religious fervor and ignorance. When this was done you had implicit confidence in every statement in that book of chronicles and traditions. You are still convinced it is Divine emanation, and so are we; but we look at it from different standpoint. We reverse the order of the outlook, regarding it from the an- tecedent edition; hut you have ever regarded man from the standpoint of the Bible. Your Bible is archetypal of the God-Head and GROWING FORM of Divinity in Hebrew evolution. Their traditions and chronicles are measure of degree of progression only. The Bible is chronicle of Jewish growth. Its later products are, therefore, always higher than those which preceeded them. The truest, best and highest form of the majesty of the uni- verse contained in that wonderful human chrysalis of Divinity is the Great Nazarene. His misfortune was in UNFOLDING THE DIVINE IMAGE more rapidly than the rest of his race, his crucifixion being the price extorted by popular homage to the traditions of Moses. ITE HAD OUTGROWN MOSES AND THE PROPHETS. Jesus Christ is by far the loftiest character in the Bible. He was not pure Jew, however, but 33 had FOREIGN BLOOD in his veins, developing more rap- idly in consequence. Nor his hair, nor his blue eyes, nor his face is Jewish, but rather North German. The doctrines which he taught are charming, are sweet indeed, and will live for- ever ; for what is true is imperishable. His poverty, early ed- ucation, and kind disposition, made him unusually patient and forbearing, whilst his wandering and romantic life, with its periods of abstraction, contributed in large degree to hasten cerebral evolution. He mapped out the line of progression the intellect must take to see Divinity from human standpoint. Being true growth, lie will be always luminous figure-head in past time, worthy to be beloved. The misfortune is his follow- ers worshipped him, and in their credulity and ignorance made him one of the God-Head. And in order to carry conviction in that age of superstition made him do incredible things. He was an enthusiast contributing somewhat to the result. It is irrational in you to be forever relegating all virtue to Revelations. Your Revelations pale in presence of the pro- nounced character and lofty virtue of Christ. Those Jew evo- lutions of internal consciousness were far transcended by the Nazarene. His admixture of foreign blood made him much greater than a Jew. A pure Jew is a Mosaic worshipper to- day, and will ever be so long as he remains a Jew. Large numbers of the human race have outgrown that species of men and their silly legends, passing them in the race of evolution, their bigotry and exclusiveness having been their ruin. They attempted a nobility upon a false basis, sticking to a form of religious evolution, saying they were “God’s chosen people.” It is not strange such bigots should be left far back in the past with the God they had monopolized, and had met so often in secret rendezvous, to gossip with about fallen man, to carry fresh messages to the wretches who had had such a fall, and had set their hearts against Him. There is no proprietorship of Divinity on part of the human intellect. The animus of offence of the Nazarene was that he preached to the Gentiles, striking a blow at the vital point of their false nobility. Since then the intellect has continued to grow away from the Jew, leaving him farther and farther in the midst of the decayed past. In his heart of heart man feels the Jew to be in his way and hates him. Nature is true to herself. It is the sol- emn duty of theology to gather what it may find of Divinity and of virtue in that remarkable Jewish book and consign the rest to the Jew. What you take away is not his. The Testa- 34 ment holds all the virtues of the old Bible without its abomi- nations. There has been tacit performance of this duty, a recognition of the fact that we have outgrown Moses and the Prophets. Theology has done great harm by unceasing effort to resus- citate and perpetuate upon present time the crudities and stu- pid sayings of a barbarous age. The mound it has reared with the bones of those who ever protested against the abnormality, is oppressive sight to look upon even in the setting sun of receding time, under the mellow light of memory and human charity. Theology will have hard effort to get away and be off to the great future. You could be of incalculable assistance to high- er growth of Divinity by promoting thought ; but instead of doing this society has to pull you along by main force. You linger about the tomb of Jewish life. You belong to the pres- ent, not to the past. The 19th century has left Moses and his savages far to lea-ward upon the ocean of thought. That bloody ground has been fought over sufficiently often, and that you came up out of that heap of ashes is no reason why you should be forever returning to it and make attempt to burrow into that enormous sarcophagus. You take exam- ple of a roaming tribe of savages as proper mentors for the 19th century. You go to the infancy of a race for intelli- gence. Man has only one childhood, the other is imbecility. It is pitiful to have you ever standing with your face backward drawn by the loadstone of mental inertia to that past. You are forever looking into that gloomy graveyard, trying to de- cipher the hieroglyphics of deceased species of men to make out which was greatest Your homage is so deep and your servility so mean that their most suppliant slave could do no more, memorizing every word you may find, and embracing every fossil and piece of rottenness. Onward and upward is the line of life’s momentum—not DOWNWARD and BACK- WARD. That Golgotha, the Past, you are to stand upon, tracing only the rootlets of your language running into that vast cemetery. WHO MEMORIZES THE PAST IS LOST TO THE FUTURE. It will crush his intellect. The more he rumin- ates through that gloomy arena the more he grows like it, in obedience to the law of environment. What of the rootlets of his language, what of art, what of science he may find let him seize with avidity, and turning 35 his back upon the accursed spot, his face to the great future, step out bravely in the fulness of intellectual manhood, the glory of emancipation full upon him. If he does not thus he becomes a toadstool, lost to the generations which are to come after him. The mind of Socrates and Seneca had not origin in Reve- lations, nor any of the greatness you call Paganism. Calling names does not remove the trouble nor make falsehood true. Your Revelations never produced anything; on the contrary, were evolved out of what had been in existence for vast period of time, to be themselves supplanted by future growth of in- tellect. There is a book so old compared to which your Reve- tations are in feeblest infancy. Do you wish to know where Ihe infant had its birth ? Be patient. The Hebrew intellect evolved Revelations out of its inner consciousness, reading the passages written on the walls of the temple in which it dwelt. It had partial consciousness of the vast significance of its abid- ing place, delivering itself accordingly. It was confused ar- ticulation of the order of the universe through the momentum of his own organic form, and foreshadowing of the possibilities of cerebral growth and mental motion. But it was not near so great as was performed by Jesus of Nazareth, though the Evangelist had fine mental power exceeding any other of his species wdio came after him, till the men of the 15th century came upon the stage, since which time religious momentum has been an ever increasing one, growing more and more conservative and more in harmony with universal order and constitution ot the visible universe. Intellectual liberty has accomplished much for religious sentiment, taming its natural ferocity and impatience, making it lovable. But Theology has work to do before adjustment will be complete. It has strong- est reasons to justify its constitution of the God-IIead, but its duties only begin here. Your high vocation is to aid mankind —living men. You are living in present time; tell us what you know of it. I would not stand there any longer ringing up the past, gesticulating with some violence, talking a great deal, and at times shrieking about this past. What men wish to know more of is present time, and less of the past than it has heretofore been crammed and stuffed with, till they can- not endure it any longer and leave you in disgust. I)o all the good you can in God’s name; it is your high privilege and bounden duty; but do you not see what is taking place all around you? You term it growing cold in the cause—a fall- 36 ing away from grace. God help you out of your infatuation. The truth is men are tired of this ever ranting of the past. Mark you, if you continue it longer your pews will contain only women and children, half-grown men and half-grown wo- men. You will have gotten rid of men. Study the matter a little more attentively and notice whose church is fullest, and where intellect pays profound attention. The revelations men will listen to must be of present time, and what you are doing to help men out of the Slough of Despond. Talk less of the past and make report of all the earth that you may hear from, what men are doing for themselves, and how you are assisting them. All men are your brothers, and some are in want of everything but life—they are tired of living. This is horrible in the extreme. May you not do more by living in present time and aiding these men a little by intelligent instruction how to go to work upon their environment to improve matters. Your catechisms do not teach them; on the contrary, they make attempt to rattle up the past. Never was child so tired of catechism as are grown men of this unceasing ding-dong- ding about those Jews of yours. Their NOM ADIC descend- ants are indifferent; they never stop to listen to you. Mayhap they have bad judgment, Pardon us, but we had fancied your vocation had reference to living men and not to dead ones. Teach men how to live, that when dying blessing you you shall be blest. Say you it is irreligious ? Irreligious! that is word of yours, coined in the mint of your imagination. Know you who man is? Read from a volume, containing text so old compared to which, in point ot time, your Jewish chronicles are but moments to countless cen- turies. Open the Book of Nature to find out the meaning of things and how your text came to be written at all. Learn how man articulated thought which is imperishable, beginning to do so in remote time and gaining in intensity as he jour- neyed on till the present time, thought being an ever-growing quantity. Years and years ago he had attained a point of ev- olution when inner consciousness could make out the foot- prints of a Divinity within him. lie said startling things to his auditory after these communings. All systems of theology have had such origin, ever becoming more and more distinct in utterance, till at last in those Jewish chronicles there is ev- olution of a Trinity in the God-Head. And religious convic- tion of the existence of a Great Book in which all things are written is also true. There is such book—it is the human body. 37 It is susceptible of demonstration upon an anatomical basis and physiological performance that there are three dominant forces in the universe. We live in a tripartite government who operate the heliocen- tric system through inflexible law by assistance of five execu- tive officers or members of the cabinet. There is difference in degree of power in the God-Head, as also in the cabinet, since there is a central figure in the former and a central figure in the cabinet. How may one form such opinion ? And where is evidence to support such statement that may undergo intelligent inspec- tion ? Proceed in the order of nature and follow patiently the steps of the journey to the highest point of observation, begin- ning with the first letters of life’s alphabet in the Geological strata, and proceed to acquire knowledge until you come to the HUM AH BODY, when you will be qualified to translate it. ANATOMY IS A LANGUAGE. The three great pon- derables—earth, air and water—constitute THE TYPE The three imponderables—light, heat and electricity—the forces which are used to set up this type for publication of the uni- verse. The leaflets are in the flora and the fauna, the com- pilation of it all being in that latest edition, the Human Body. A last edition should embrace the virtues of all preceding ones; this greatest of books is no exception to that law. Man contains everything.. His Head is impersonation of governing majesty; his Body a miniature of the heliocentric system and book of chronicles, Regard it as complete in itself, the mem- bers being attached to it for its support and direction, whilst the head, the great seat of power, is far above it. That little heliocentric system has support on two great props or crura, which terminate in two pedestals. These pedestals have five terminal digits each, with a great inner one on either foot, called the great toe. Set down these factors to themselves and proceed up either colum in search of higher expression of these factors. Evolution has a scale of ascent. There are five Lumbar Vertebrae, through whose articular facets the whole trunk is rendered flexible. Regard the upper extremities. There are five terminal di- gits to each of these, with the strong inner one in the thumb. Here is higher elaboration and more marked individuality in the several members. Persevere in the ascent; the head is reached. Look at that remarkable semi-circle of the five senses, with the strong, well-marked inner one giving charac- 38 ter to the whole face—the nose. These factors are all around your universe. Moreover, they guide, feed and sustain the body. These are representation ot the five great cabinet offi- cers, the presiding one in the middle. Where is solution of the Trinity ? Is not all that great reach of brain substance over and above the semi-circle of the five senses ? Does not the intellect reside here as autocrat of all below ? Do not the limbs obey it and the senses heed its bid- ding? They may all fail, yet if the intellect survive to ask for food and raiment life continues in the body, as in the paralytic. Look at its place of residence; there are two great brain masses—the right and left hemispheres. Is this all ? Do they not generate electric fluid, which reaches with lightning speed throughout the entire body, commanding it to perform ? What power would the brain exert over the body in the absence of this pervading spirit ? Religious sentiment has evolved a Trin- ity, one of them the Holy Spirit. The relation of the other two, as being father and son, may not be shown to exist; nev- ertheless, one is much greater than the other. 'In this inspec- tion follow Nature closely, beginning as before at the ground. There are three bones to the leg, the tibia and fibula below, the femur, or thigh bone above. The latter is the equal of the other two in strength and weight; moreover, is above them. Ascend higher. There are three great pelvic bones, the os sa- crum, higher than the others and base of support to the bod}7, regulating the two side bones and capacity of the pelvic basin. Look at those two side bones the ossa innominata They are resolvable into three bones each, a great broad portion above (os ilium,) equal to the os ischium and os pubis, forming the lower two portions. Ascend to the upper extremities. There are three bones to the arm, the upper one in the os humerus, the equal of the two bones below, radius and ulna, forming the skeleton of the fore-arm. The two great crura, with assistance of all-pervading nerve fluid, support the body in erect position and determine which direction it shall move. The two upper extremities that feed it would be impotent in the absence of the all pervading nerve power. Three then is the dominant factor to animal organisms, and number of the potentialities which rule its behavior, there being difference of virtue in them. This great power sits above the solar system, the seven cervical vertebrae representing the seven cortical layers. The number of bones, two hundred and forty, have representation in planetary space. The twelve ribs around the heart, and 39 twelve dorsal vertebrae, are its Zodiac, holding all this system together, whilst the great central organ of the heart sends out the life-giving fluid that builds up everything. So much for the constitution and relations of the august po- tentialities of the vast autonomy of the universe, written in ana- tomical symbols through Life’s Form. Let us see further into this wonderful book to make out how much the Trinity is spo- ken of. There are three great factors to the circulation of the juices, viz: Atmospheric pressure, muscular substance, and nerve force There are three great vessels in close association in the umbilical cord which constructs life’s form. There are three comprehensive systems of vessels composing the vascular apparatus, viz: Arteries, veins, and lymphatic vessels. There are three great openings through the diaphraghm for transit— the three large conduits, the oesophagus, aorta and vena cava trunk. The venous tube of intestines has three great anatomi- cal sections, viz ; 1st part from mouth to pyloric end of stom- ach ; 2d, from stomach to colon; 3d portion includes colon, caecum and rectum. Either of these portions is resolvable into three subdivisions, which are again resolvable into a like num- ber of lesser divisions The buccal or mouth cavity, the pha- rynx, and stomach are in the first portion ; the duodenum, je- junum, and ilium in the recond portion ; the ascending, trans- verse, and descending colon form the terminal portion of the tube, etc., etc The renal territory has extension of the law. The kidney has its cortex, its medullary substance and pelvis; the latter has its three infundibula. The bladder has its three tubes, two receiving and a discharging one; so has the womb. These ovoidal bodies have each three grand compartments or regions. There are three great divisions of the nervous system—the brain, spinal cord and smypathetic nerve. Nerves have three fundamental elements—neurilemma, axis cylinder, and the white substance of Schwann. The body is divided into three great divisions—head, trunk and extremities. Its envelope, the skin organ has three divisions—epidermis, rete mucosum, and cutis vera. The trunk contains three great cavities—the cranial, the chest, and abdominal. Either of ydiich is resolv- able into three lesser ones, as in the cranium there is the right and left hemispheres and cerebellum, the entire brain substance resting within the three great fossae at the base of the skull itself. The chest has its two pleurae and pericardial cavities. The abdomen has its compartments in the hypochondriac re- 40 gions, the soft abdominal regions and the pelvic excavation, containing organs with a fundus, a body, and a neck. The extremities have three great natural divisions, viz :•—the arm, fore-arm and hand ; the thigh, leg and foot. The hand is re- solvable into the same number of divisions, viz :—carpus, met- acarpus and phalanges. There is a shoulder, an elbow, and wrist joint; a hip, knee and ankle joint. The law has exten- sion to the bones themselves. There are long, flat, and irreg- ular bones. Bones have an external, an internal table, and an intervening diploe. There is a shaft or diaphesis and two ex- tremities. There are three inlets into the body for the trans- portation of the solids and fluids for the support and construc- tion of life’s form, viz :—the mouth and two nares. The nose has its two alse and septum, and its bony skeleton has three pieces, two ossa nasi and vomer. There are three turbinated bones. The eye has three great di visions, viz: the aqueous, the crystalline, and the vitreous humor. Making one more reference, we will refrain from further reading at present, since the matter has extension into the mi- nutia of construction, running through the fauna and the flora. Sound is transmitted over a mechanical contrivance eloquent with the Divine autonomy. The auditory apparatus is divided into three great divisions, resolvable into an equal number of subdivisions of generic factors, viz : the external (auricula) in- cluding the external canal to the membrana tvmpani; 2, the middle chamber (the tympanum,) lastly, the labrynth or inter- nal ear. The first resolvable into the helix, the lobulus and the concha, with subdivisions into the tragus, the anti-tragus and anti-helix. Sound is conducted through the middle cham- ber over a chain of three bones (the malleus, incus and stapes,) and delivered into the internal ear or labrynth. This is the most complicated portion of the mechanism, marking progres- sive increase of complexity. The labrynth is divided into three portions, viz : the vestibule, semi-circular canals and cochlea. These divisions are again resolvable into an equal number of subdivisions. There are three semi-circular canals, enclosing an equal number of divisions of the auditory nerve. When the intellect rises up from the contemplation of this wonderful mechanism it must believe in a Divine intelligence, and have impression that the vast autonomy of the universe is a tripartite government, publishing the Gocl-Head in the book of life—the HUMAN FORM. Out of the inner conscious- ness three grand words have audible articulation from that 41 great seolian harp, the human brain. Thou, God Divine—Om- nipotent, Omniscient and Omnipresent! Is it longer matter of wonder, thou Man of Nazareth, thou didst deliver immortal utterances? As long as the human race continues thy memory will evoke unspeakable love. We have seen that three is dominant factor in animal me- chanisms, the foundation of anatomical construction, and that the factor live is administrative only, never suffering displace- ment from this relation ; and the influential position they hold outside the organism has continuation to the internal territory, as is well exemplified in the hepatic organ. The liver super- intends and watches over luematosis. All the blood gathered by the radicals of the portal vein is passed through that won- derful mechanism for filtration and higher elaboration. It has five as its ruling factor. There are five ligaments, five lobes, five vessels and five fissures. It holds pre-eminent position in the abdominal cavity, both in relation to function and height of elevation over the other viscera. The cabinet has representation in the blood organs, a con- tinuation of the external relation supervising the manufacture of blood, as they had directed the body for securing the rough material for its elaboration. A rising scale of consciousness is measure of the tone of vi- bration of the cords of life’s great harp, whilst History is chron- icle of the journey, The religious revolution of the 16th cen- tury is measure of intellectual momentum, extending itself over the cerebral cortex of large numbers of the highest types of the human species, testifying to the truth of the immortal utterances of Christ with reference to the God-Head bodily, the God-Head spiritually, and true relation of man to man. The key-note sounded by Sir Isaac Newton and M. Harvey is fur- ther evidence of intellectual momentum and diffusion of the wave over the entire solar mechanism, with in vasion of life’s form, the product of stellar motion, the mighty artist sitting above originating that vast mechanism and sustaining it. Mat- ter is visible evidence of imperishable law, hence as eternal as the law itself. Unnatural event is spoken of in Hebrew Chronicles quite often, but with steady diminution in frequency with the increase of intellectual evolution. Unnatural event there never was in the earth, nor may it be shown to be in keep- ing with the harmony of all-pervading law. Imperishable tes- timony engraven with fossil flora and fauna declares in lan- 42 guage not to be mistaken, that progression has been steady and uninterrupted. It is foolishness to say otherwise, and bad judgment to attempt to invert the order of events in the earth. The observant Israelite saw the evidences of a flood all around him ; the rest he evolved out of his imagination. The intel- lect of to-day knows a little more of the history of the flood, and of the composition of man’s body, than that remarkable waif of the bulrushes adopted by Pharaoh’s daughter, and only freedman in Egypt. Such knowledge was not to be had in Egypt among slave-owners, let alone ignorant slaves. By reason of his superior education he had no difficulty in perform- ing a great role in the face of this simple race, and to impose upon them to any extent, Having run away with him from their Egyptian owners, there was nothing for them but what these nomads could take by violence and brigandage from un- resisting nations on their line of march. The nomadic exist- ence which the freed slaves led for so long a time is a peculiar- ity of the race. Moses had his hands full; no one knows how much trouble he had with the savages, but may form some idea of it from the number of extraordinary appeals he made to their superstitious fears, keeping them in the traces of mental discipline and restraint by terrible denunciations, and not un- frequently necessitated to make fierce example of the more re- bellious. He ruled his Hebrew ruffians through terrorism, not stopping at anything, making frequent use of their faith in the supernatural to accomplish his end. It was a thankless ser- vice. He finally disappeared in a mysterious manner. His pupil and successor, Joshua, was like him in many respects, for it was he “who stopped the sun” in order to prolong a bloody massacre in the mountains of Palestine, which he and liis bri- gands were wrenching from the rightful owners. After hav- ing beeh despoiled of the arable lands of Palestine the forlorn natives rallied in the mountain passes, fighting the best they could in defense of their little homes and firesides. But this horde of nomads had to be kept employed to prevent mutiny over the spoils they had taken. They did not actually want the soil, for that race never sow and reap as other races. The Books of Moses is wretched tale of murder, rapine, spoliation, crime, and heinous immorality. One thing we may rest as- sured of, they never told the half of their infernal deeds, being their own historian. If such be virtue to be lauded in this hour, God save the name. One of the most astounding circumstances of this age of civ- 43 ilization and recognition of human rights (the right of property being held sacred,) is that pulpit orators should elect this sav- agery and diabolical performance as exemplars of God and re- ligion. It is amazing. If it be attempt to inhibit inquiry and investigation it is a great mistake. Mankind will sit in judg- ment upon those deeds despite the protests of theology. The love of truth for its own sake is growing quantity in the hu- man intellect, THE MEASURE OF INCREASING VIR- TUE and of mental evolution. It is organized crime on the part of theology to make attempt TO SUPPRESS IN- QUIRY. TRUTH DEMANDS INVESTIGATION, and Moses will have enough of it. Religion is child of truth ; su- perstition is other name for ignorance—it is the night of intel- lect. The stakes have been much advanced of late into the stygian darkness through the courage and industry of scientific engi- neers, and proclamation of this sort is made all along the black border. EVERYTHING MUST BE SUBMITTED TO INSPECTION OF THE SENSES. Education of the senses is the true mode of informing the intellect. To OBSERVE first, to THINK afterward is rapid care for dreaming dreams and evolving hallucinations. Man now knows he advances ONLV BY HIS OWN IN- DUSTRY, and performs HIGH or LOW LABOR according to his knowledge and opportunity of being taught, never hav- ing received the slightest assistance along the entire journey from any Revelation, good, had or indifferent; on the contra- ry, has cause to remember them with unspeakable sorrow. He is aware of the advantage of A GOOD ENVIRON- MENT, seeking how to improve upon it for more rapid con- summation of what he wants in animal life and plant forms. And he will do better yet than ever before when he submits himself to the law of hybridization more completely than he has yet done, preferring to add up the potentialities in the mind, stored in cerebral convolutions, rather than promote the aggregation of personal propertv and landed estate. THERE IS ONE TRUE AND IMPERISHABLE NOBILITY—that of intellect. Nature is true to herself. The AVORLD IS DOMINATED, and will ever be, by HYBRIDS OF THE HIGHEST TYPE. The English are highest order of hybrids (there is difference in them ) MEN MUST HAVE ADDI- TION as well as horses and roses, beginning with the best type of the highest species. Republics do so well by reason of less resistance to this scheme of human culture. They need to un- derstand it better than they do. The eternal order of nature is to look upward through the affections, to climb higher and higher, ever climbing. To step down is a violation of the first law of nature. Onward and upward in unceasing struggle for better growth and higher elaboration is the all-pervading and dominant law of evolution. Thought is evolved OUT OF LIFE’S FORM, being high- est product of it, hence THE TESTIMONY GIVEN ALL ALONG THE JOURNEY OF MENTAL GROWTH IN CHRONICLES kept by different species of men, differing in quality according to degree of evolution, constituting the letter of their religious faith which they cherish and preserve. Ev- ery species of men who have advanced to sufficient evolution to keep a chronicle of events have religious sentiment the most conspicuous, with great leading characters as figure-heads, oc- curring at long intervals of time, so slow is mental evolution. The species of men dwelling in Palestine kept good chronicles and preserved them well. Being a high race they evolved much of the archetypal form of the God-Head, which has such faithful correspondence to that evolved by the inner conscious- ness of the 19th century. Being archetypal it is imperishable. The duty remains for the higher intellect of this age to elimi- nate it from the vulgar vesture of Jewish habits in which the priceless gem is embedded. Amid the rubbish there are many beautiful pearls. What matter is it, so far as truth be spoken, which distinct species, OR INDIVIDUAL OF THE SAME, first elaborated life’s highest archetypal form, in religious evolution, and gave articulation to imperishable human thought, and a voice to si- lent language in the mind of his fellow-men, who by reason of this fact crowned him a hero and a*God? What the intellect needs is exact information of what it is, and how it exists in this terrestrial environment, holding on to true information and rejecting mythology Superstition is suffering much re- trenchment, growing less and less in power to do harm. We live in the midst and are evolved out of imperishable af- fections. It is mark of childishness and savage credulity to repeat old legends making man a stake in a game of chance, the cultivated and informed falling to the devil. It seems incredible at this day how the human intellect could entertain it. One, however, should remember there was such time when it knew how to satisfy only immediate wants of the 45 simplest kind. It has grown much since then. The bonds of mental slavery are cracking with fresh fissures, everywhere falling off numbers of men. The hardest work man has to do is the cultivation of his reasoning faculties. Environed in a thick fog of superstition, the way has been most difficult and progress very slow; yet some advance is being made all the time. The world is bet- ter than it was even a century ago. Who says differently speaks without law and against overwhelming evidence. He speaks of his sensations only, not of human growth. However slow it he, ultimately the true remains to tower above the false. At last the intellect has reached a point of elevation where it may no longer suffer intrusion from devil or triar. They per- ish in the attempt to reach that ascent. Since the law of evolution is made out, a rule of general ap- plication is of ready formulation, viz ; the amount and degree of unreasoning faith (superstition) is measure of defective cer- ebral development. There may be degree of intellect with large amount of special knowledge, yet the individual fall be- low the highest cortical expansion ian as he sinks in credulity and faith in the marvelous. The reasoning facul- ties are in abeyance, whilst memorv is enormous. The indi- vidual PERFORMS ACCORDINGLY. The female sex, as a class, have six to eight ounces less brain substance than males. They are very superstitious and fanatical. That sweet frailty fancies itself to have one rib more than man, thinking of Gen- esis. Her flexible nature takes its shape from the mould of that rugged Hebrew mythology. One may not run away from his own organization. He is inside of HIS FORM and must stay there, working away with all his might upon his brain substance. How to grow men- tally is the problem of problems. To change one’s height or his sex is an impossible performance; he is walled up in an unyielding casemate. Man has voluntary power to effect LIMITED alteration upon the environment for promotion of growth to higher cere- bral elaboration, which he accomplishes by patient inspection of visible properties of matter and knowledge of physical law. He desires to do well—is doing better than he did. He makes attempt to follow example of Deity in constructing wonderful mechanisms. Steam machinery is not feeble imitation of ani- mal mechanism. If man could find what he is seeking for so earnestly—PERPETUAL MOTION, the thing would be done. At present the terms upon the slate read: the highest animal mechanism may evolve and elaborate other lower forms of mechanism, a motion within a motion, having gradation. There is persistence of the law—THE CREATOR IS GREAT- ER THAN THE CREATED. To conclude :—in the illimitable expanse, as far as mental motion may propel its wave till it exceed the solar ellipses and break upon the God-Head, there is continuation and persist- ence of law. Everything is conserved in imperishable law, and IT IS HOT POSSIBLE FOR ANYTHING TO BE LOST. There are no fragments falling into hell. Nothing may escape from the embrace of the solar mechanism hut THOUGHT, which is potentiality of the God-Head Itself. All is well. Gentlemen, you should travel more. Those of you who are able to do so commit a grave error by neglecting it. Instead of marrying so soon, your first savings should go in this direc- tion. Place yourself upon a steam carriage which intellect carves out of the children of the forest, and sends rushing over the great magnet of the earth by aid of solar heat turned loose upon iron cylinders, (having laid dormant in coal for thousands of centuries,) and look you out of the window to the right and to the left upon everything, as if with intent to purchase. Go down to innermost depths through hidden stairways dug in the earth’s side by the children of men, intellect leading the way, and examine the leaflets carefully as you descend. Visit sub- terranean passages carved by hidden streams with blind fish in them. The sculpturing in mammoth cave, of vast halls chiseled out of solid rock, with bottomless pits leading down into infernal blackness, with jaws standing ajar for him who stumbles, will give impetus to thought and grandeur to pres- ent time. From high plateaus on the Rocky Mountains cast your eye down declivities more than 5,000 feet deep, (some of them half a mile in width,) dug out of solid limestone by etch- ings of water which falls only from the dew of heaven. The ocean is mother of all that marble which she is transporting hack to her own bosom again after such long absence. Thous- ands of centuries ago her myriads of swarms of coral insects did the labor of constructing it, when a vast subterranean force suddenly elevated the sea bottom, and you are regarding what has happened since. How many drops of dew did it take to do all that carving? Are you disposed to enter into the calcula- tion ? It is madness ; however, if you are bent upon the in- 47 quiry, set clown as lirst term of the proposition the number of grains of sand on the Pacific coast, and multiply them by suf- ficient drops of water to chisel out the flinty crystals from the elevated plateau and transport them to the ocean side. The sum will be an unspeakable number of years. You must not stop at this. Place yourself upon a steam mechanism which wades out boldly over the powerful magnet of the ocean, drawn by solar force under guidance of intellect, and when the steam- boat rides you as a feather upon all that motion, and you look from sky to sea, and from the ocean to the firmament, where motion is yet more vast in the wake of rolling planets, and your inner consciousness is awake at last to the momentum of the universe, think of the despised Copernicus—of Giordano Bruno, of Galileo. The Teutonic Pole was out of your reach in the midst of the brave Germans, but what of the two latter ? On February 17, in the year 1600, a most brutal public murder, a most savage and inhuman one, was committed in an open square near the Vatican. Giardano Bruno was burned alive. The Nazarene perished by crucifixion for unfolding the Trinity, and the divine rights of man. The Italian was incinerated for unfolding the universe, and the heroic virtue displayed in the midst of the burning fagots is the peer of anything in history. The Religious Revolution of the 16th century had its army of martyrs drafted from the noble and heroic of the earth; but the 17th century led off in the struggle for intellectual liberty with as noble a victim as Theology had ever burned at the stake or tore into ugly ribbons with the teeth of the inquisi- tion. BIGOTRY IS A BLOODHOUND; when fully aroused it is a monster. The time it takes to cool its blood is mournful in the extreme. That poor old man, Galileo, in his 70th year, to save his life was necessitated to kneel upon this tragic ground thirty-three years subsequent to this event, and made to recant the Copernidan theory and to promise he would never more teach that the earth revolves and the sun is sta- tionary. To make the abjuration more impressive, and if pos- sible more binding, they caused him to spread both hands out over the Hebrew chronicles and dressed his noble person IN SACKCLOTH. Notwithstanding they condemned him to imprisonment at the inquisition during pleasure; finally he got free of a living death upon his taking a vow worded by them, declaring his detestation of the proscribed opinions, with a promise to recite once a week for three years (as long as they thought he could live,) the seven penitential psalms. But 48 they set a watch upon him, and when that immortal philoso- pher and mathematician was cold in death, refused his bones a resting place. Say you ’twas the work of zealous Catholics? But for the revelations of science you would do the same to- day. You are all alike in essence. You grow restive, intol- erant—FRENZIED UNDER SCRUTINY. You of all men living are bent upon having your own way, cost what it will. YOU are helping God Almighty, whilst THOSE OPPOSED TO YOUR NOTIONS are enlisted in the army of the devil. The Calvinists hated Science and Philosophy. But the 19tli century is what it is because of the labors of those matchless twins. They have rent into fragments that horrible and mon- strous theological web, with its infundibulum resting upon Rome, the nidus of its TARANTULA, where human flies ad- ministered to it. For centuries nearly all of Europe, boots and spurs, was in this web. Superstition also has its cortical layers, where fossil ptero- dactyls and monstrous megatheriamaybe found. In the 19th century smaller and more agile forms have taken their place. To keep up a show of life in Hebrew chronicles a new art has introduction into human experience called Allegory. So that when some long-established opinion, moss-grown and hoary from Mosaic time, is forced to yield to inevitable logic, you slip in quickly by dextrous movement a flaming placard with only two words written upon it—“an allegory,” and place it over the ruined text, every word and letter of which you had previously insisted was true and unchangeable. You are aware this invention is designed to conceal a new rent in the sides of the Ark of the Covenant. THESE UNHEALED FISSURES are now grown very numerous, and presently the whole truth will be out, when all will be but Allegory and BIOGRAPHY. Ah, gentlemen, it is common circumstance with you to do this thing, but is it honest? Is it just to intellect ? Is it ALL THE RETURN you propose to make for its vast labors, its prodigious sacrifices, and last, though not least, for unspeaka- ble sufferings endured at your hands ? Remember the law:— be who asks for justice shall do justice. One dense shadow after another is dissipated by the white light students place underneath its black drapery; and one falsehood after another is nailed to the counter with unyield- ing rivets wrought by science out of the furnace of truth. Hark you! for you are to undergo investigation also; there are 49 men coming who will sit in judgment; and what is noble and true in your utterances will live to posterity, hut what is false and hurtful will perish utterly. Adieu ! CHAPTER III. THE TERMS OF INDEPENDENT ANIMAL EXISTENCE. THE PLACENTA. The question of FERTILIZATION throughout the fauna and the flora is a settled one, and for the purposes of this pa- per there is no occasion for a recapitulation of the pains-taking labors of indefatigable students of nature, in observations of the nutritive changes which subsequently take place in the fertilized ovum in the march of elaboration. It is sufficient to know that whilst lower forms precede the higher ones, the lat- ter must contain ALL THE ESSENTIAL FACTORS of the former, receiving yet clearer definition and more emphatic enunciation; hence, whatever function is present in the pla- cental organ must not only have continuance in the new or ganism it is constructing, but receive additional enlargement and more distinct provision. Not one factor may he ignored. This circumstance being irrevocably fixed by Nature, it is in order to set down an interrogatory upon the slate, viz : What kind of work does the placenta perform in foetal elaboration ? Whatever this is must he added to the new organism, since Nature does not abolish principles; on the contrary, she has an ascending scale of elaboration of mechanical contrivances for their accommodation and perpetuation, ever promoting the best arrangement. It follows that whatever principle is operative in the placen- tal mechanism during the intra-uterine environment, to have perpetuation in extra uterine existence must have incorporation with the new organism which is being constructed. There is no such thing as abolition of principle, but displacement of a lower contrivance by the substitution of a higher one, is the eternal method. Nature cannot change the vital scheme at birth ; she simply enlarges the individual mechanisms, adjust- ing them for the rude experiences to which they would have exposure, at the same time to enable them to perform agreat- er amount of labor than the primitive organs. Therefore, to :>1 find the essential factors of independent animal existence, the initial point of inquiry will be inspection of the contents of the womb (taking example of the higher animal species) before expulsion, making note of the essential factors, a prime ques- tion being, what is the placenta ? There are two great factors in placental functions, viz : 1st, It manufactures its own blood, using the venous juice of the mother for the purpose. 2d. It lias the cardiac power to dis- miss this blood out of its cavities into the systemic circulation of the animal mechanism which it is building, else the work of construction wpuld not go on. It must be apparent to brief reflection only, that separate and independent existence would be impossible without previous absorption of these two great factors resident in the primitive placenta. To proceed to the minutia of detail. Placental mechanisms manufacture blood by importations of nutritive material from outside, extracted out of the mother’s blood. To accomplish this there is arrange- ment of innumerable little organs (placental villi,) which ex- tend into tortuous venous canals containing the elements needed in foetal elaboration. No blood of the mother circu- lates in the foetus; on the contrary, it is but the juice out of which the villi make appropriatiation of what is needed for the special labor in hand. Hence it is essential that the new or- ganism should have such power of manufacturing blood after it will have been cut off from the placental function; other- wise it would perish speedily. We have already had occasion to advert to the great analogue of placental villi and the tor- tuous venous canals in which they feed, as having appropriate representation in the intestinal tubing, and vast numbers of villi feeding in its white juice. In respect to the second factor, or the cardiac force, to ship the blood placental mechanisms manufacture into the systemic current of the foetus, such function must be conceded as afore- gone conclusion, since however abundant or however perfect blood elaboration may have been within the placenta, if it lack the power to get rid of it, it would go for nothing, since noth- ing would be accomplished upon the foetus. But it does have such power, for the placental souffle and the heart of the in- fant are overheard through the maternal structures, each at its own special labors. There are two hearts performing work upon the foetal organ- ism—one for the manufacture and importation of blood into its systemic circulation, and one for its distribution to the nu- tritive processes, both performing work at the same time. 52 Hence it follows, the new organism must also have full repre- sentation of this most important and essential factor, to take its place after amputation of the primitive placenta in two hun- dred and eighty days. Up to this period that organ had sub- served three important functions, viz : 1st, the manufacture of blood; 2d, the oxygenation of blood ; 3d, the cardiac force to dismiss it into the body of the foetal organism. These factors are unalterable and eternal ; they remain ever the same and must ever continue so. The problem is simple enough in for- mulation. The primitive placental mechanism answers the vital necessities of a twelve-pound child ; but what is placental compensation to fill out the requirements of a three-hundred- pound man ? Where are placental mechanisms located in the human body, taking example of the highest type of animal life? I have made discovery that Nature adds both factors to- gether, combining them into one, by making an enormous car- diac organ—the heart of the independent animal—and suspends the mechanisms for the manufacture of blood by means of re- duplications of its endo-cardial lining, after the manner of the forming of the valves in the little primitive organ, and known by the anatomical names of peritoneal and pleural ligaments, whilst it delivers the blood so manufactured from substances called food, into the systemic circulation by its own cardiac power through a special umbilical vein (the Vena Porta.) The pulsations in the placental souffle have large analogue in'res- piratory movement, which are the pulsations of the great heart of Independent Animal Life. This heart contracts upon blood contained in a system of flexible tubing instead of upon naked blood as in the prototype In the rudimental organ the villi of the chorion in due time become the villi of the placenta, and projecting into venous canals make appropriation of needed nutrient constituents, which, after passing through the placental mechanisms, is de- livered into the radicals of the umbilical vein The homologue of this is seen in the transfer of the products of the intestinal villi to the radicals of the portal vein, the new umbilical vein of the independent animal, under safe protection against exter- nal violence. And the cardiac power resident in the placenta, represented by its muscular substance, has its great analogue in the muscular substance of the abdominal walls, including the diaphragm. When it contracts the blood contained in the portal vein is driven over the old road-beds through the liver that blood of the primitive umbilical vein had previously 53 traveled, making use of every canal and passage-way in this comprehensive system of tubing, (for it is all umbilical,) with final escape into the ascending vena cava trunk by the com- mon channels of exit the of hepatic veins. The placental an- alogue is not yet complete, for perfect blood needs to he oxy- genated, which is accomplished through the mechanism of the pulmonary apparatus, where exposure of its carbonized iron takes place on a larger scale than in the intra-uterine environ- ment. The oxygen of atmospheric air and the oxygen of the maternal blood is the same, whilst the magnetic force which deoxydized iron in the red corpuscles exerts on oxygen has uni- versal application. Oxygen will make its way through diapa- nous membranes anywhere to satisfy its powerful affinity for unoxydized iron. Placental mechanisms provide for this law, the pulmonary organs being a still larger provision. Does the statement meet with objection—that the placenta has cardiac power to empty its lisemic reservoirs into the um- bilical tubing? It will be in order for him who utters this protest to show how Nature does this work; since foetal construction waits on the supplies, growing in a ratio with the amount received, else perishing utterly from its suspension. Let the circumstance be borne in mind also, that no general force can be made effective upon placental blood; a local one must be shown to exist. Atmospheric pressure must have ex- clusion, since, acting through the maternal walls, it presses uniformly upon the liquor amnii and all the foetal structures. And if extent of regional surface have influence, the body of the foetus is under greater pressure than the placenta, and the hsemic current would have reversal, going towards the placenta from the body by reason of this fact, The same principle would necessarily exclude maternal aid, through uterine contraction ; it would be felt upon everything. What is essential to the performance of this function, therefore, is a local force, sufficient for the purpose of constringing the walls of the placental reservoirs, and driving out their contents into the vein, as the ventricle does into the aorta trunk. Less than this would not be effective. It is also in order, to explain what other purpose the muscular substance of the placenta sub- serves, than the one assigned. It is expression of power. Mus- cular substance always is representation of force, (to be ener- gized on special occasion.) If it should condense itself in this instance under a ganglionic system of nerves, as obtains in the 54 heart, would it not have the effect to approximate the walls of its cavities containing blood, as the muscular substance of the ventricle approximates its walls under influence of its special ganglia? What good comes of human protest if it oppo- ses physical law? and why make captious objection? Mus- cular substance shortens when it contracts, is a physical law If muscular substance over the placental cortex should con- dense itself, would there not be corresponding diminution of placental area ? Physical law is not pent up in a corner of the body; on the contrary, has universal application. In this instance mus- cular substance is not in the central organ constrmging the blood and ejecting it out of the ventricle into the lumen of the aorta; but it is in the placenta, expressing blood into the umbilical vein. Thus Life’s scheme is rendered perfect in placental elabora- tion, and the terms of independent animal existence have for- mal statement. The placenta is not abolished at birth, but has perpetuation with elevation in the scale of vital elaboration. The several great principles represented in its anatomical construction do not suffer disruption from the vital scheme with ligation of the umbilical cord. The circumstance is self-evident—the science of Life must stop abruptly and remain stationary till full and complete an- swer be given of these fundamental constituents. The crude result of the alterations is to bring placental mechanisms in close and immediate relation with the central cardiac organ or hsemic reservoir, with such modifications in the apparatus for making blood from more crude material than that furnished to the primitive organ. The accompanying photograph, Fig. 1, is a primitive pla- centa taken immediately after delivery. It has ovoidal configu- ration. It does important work in constructing the great substi- tute which is to finally displace it. The higher growth is evolved out of the lower in keeping with the eternal order of progressive evolution. No conflict anywhere; the matter being one of co-operation in vital mechanisms over a definite roadway, in one harmonious and continuous line of march, from the simplest to the highest of life’s forms. Does any one object? What matter is it? no notice is taken of his protest, nature moving on as if it had never been uttered. Is he worse off than before he had such information ? verily not; for can 55 he not buy food and raiment all the same? One thing, how- ever, follows him: he must subsist. How to do this is a prob- lem hung up over his cradle to be taken down only in his coffin. The accompanying photograph, Fig. 2, from a drawing of placental mechanisms (taken in situ) of the independent ani- mal, is given, predicated upon the logic of vital evolution. The various systems of anatomy separate these organs, dissociating them and destroying that entity and comprehensive unity which is their peculiar and greatest virtue. It is needless to add that the casing in which it is lodged is not only essential to its pre- servation, but contributes most important aid in the labor of the blood circulation. The whole trunk is a placenta, the limbs carrying it about and ministering to it; while that pin- nacle which surmounts it all, represented in the head, but more especially in the brain substance, is the grand objective point toward which nature is bending all her energies This won- derful harp with its countless strings makes response to the lightest touch of nature and utters tones divinely sweet, or sav- age and barbaric according to fineness of elaboration and de- gree of finish. The configuration of the organ is ovoidal. The outside ovoid is higher evolution of life’s form. The law holds good upon extension of the principle, for when the abdomen, or great ventricle, is regarded its form is ovoidal, the great end up, (represented by the incurvated diaphragm,) the small end down, (represented in the pelvic excavation.) The manufacture of blood requires high order of mechanism, hence the necessary evolution of high archetypal configuration in this great territory of the common domain. The lungs are reversal of the figure, their base being down, their apices up. The explanation is in the difference of dignity in their respective labors, with degree of appropriate complexity in their mechanisms. The abdomi- nal viscera manufacture blood, whereas, the lung organs only expose it to the air. They don’t manufacture anything, hold- ing anatomical relations only with the leaflets. They afford the necessary contact between atmospheric air and life’s juices, with resulting chemical change upon either. Both are interdependent; yet the mechanisms for the manufacture of blood are of higher order than the device for bleaching it. The diagram shows the dilated intestine (stomach) pulled aside to expose the new umbilical vein (portal vein) where it disappears into the liver-substance. The terms are simple — A GREAT PLACENTA FOR A GREAT ANIMAL. 56 Fig. 3 is a photograph of the trunk or placenta of the inde- pendent animal. The head crowns this mechanism, whilst the upper extremities are suspended from the auricular appendage of either side in the usual manner. The inferior extremities are not exposed. A window is cut through the auricles at their anterior central portion, in order to exhibit the great elevation of the diaphragm in the chest cavity and the hsemic reservoir, the heart of hearts, suspended by vascular rootlets above it. At each descent of the dia- phragm the right side of this reservoir has sudden inrush of blood from the great ventricle below, passing into the tubular apparatus of the great auricles. At each expiration the left side of the cardiac reservoir re- ceives the blood which had passed into the lung organs during the preceding inspiratory act, having been charged in the in- terim with oxygen which turns it red. This rhythmic move- ment of respiration is the analogue of the souffle of the primi- tive placenta, the net product being the same; i. e., the deliv- ery of oxygenated blood into the central reservoir for general distribution. This great placenta retains every factor of the original one, with specialized mechanical contrivances of a higher order for manufacturing blood and oxygenating it; while the rhythmic expansion and contraction of the trunk as- pirates and expels blood into the central reservoir with aug- mented energy. The terms of the first placenta are fully met and nothing is lost out of the scheme of life. The trunk of animal life has cardiac force to deliver the blood manufactured in its mechanisms into the central reservoir. Nature deals in fundamental forms, rearing in the midst of all this structure in the first hours of foetal construction, a heart of hearts, as the prototype of the great cardiac temple which is to follow. The body is perfect configuration of the heart in the bosom of this cadaver; the little rose-hud of ani- mal life has perpetuation in life’s great temple. The arms removed would allow the auricular projections to extend on either side, as in the little archetype. The head, and life’s great petal (the brain) have grown out of the placenta, and should be removed. At the inferior portion of the trunk the red line is the boundary of the ventricle; what is oh the outer side relates to the lower extremities, which are only appendages for car- rying it about. The comparative anatomy has full consideration in the 57 chapter on The Heart of Animal Life. The little heart of hearts acts as a hsemic reservoir for changing the circulation of the blood from the right to the left side, delivering the same into the aorta trunk and arterial mains. This opinion has support in anatomical construction and physiological require- ment. Never for one moment do we lose sight of the ANATOM- ICAL BASIS, with adjustment to PHYSIOLOGICAL RE- QUIREMENT, looking from one to the other, then back again, from the former to the latter. Such reversal is speedy cure of anatomical and physiologi- cal misadjustment, of which there is so much in medicine. Nature being required to do impossible things to suit the phys- iology evolved out of the inner consciousness of men. No misadjustment is in greater degree than that for the circulation of the blood. A tremendous central force, having power to lift up the entire blood-column and pitch it forward into the tissues against the atmospheric pressure and resistance of ar- terial tubing, is not Nature’s mode of performing the circula- tion, but comes of a rude time of barbaric force and evolved out of the mind of that period, to be supplanted by Nature’s kindlier and more gentle method, in perfect harmony with anatomical construction of the vascular apparatus and the del- icate corpuscles. Nature’s method is much higher order of mechanism than Mr. Harvey’s mode for carrying on the circu- lation. Look at the location and surroundings of the little heart, hanging by large conduits between two great vascular organs, which have grown up out of it, becoming so large as to envel- op it. In the independent animal they aspirate blood from the right side and deliver it into the left side of the heart. In the work of elaboration something like this happens : the primitive heart is quickly evolved, but slowly and patiently, with great pains-taking, mighty auricles of similar pattern are built over and around them, closing in on all sides, when the rudimental organ becomes no longer visible, the new structure engulfing it in the vast expanse and reach of territory. Whilst these great auricular walls are being constructed most import- ant and interesting transformations are talcing place within. Two large and singular looking masses grow up around the rudimental heart, formed of a congeries of compressed tubes. The heart pulsates between these objects which have grown out of it and are fastened to it by large tubular roots, six in 58 number, counting the bifurcation of an unusually large one as two, otherwise there would be only five rootlets. In the life of the living child these rootlets are called the pulmonary ar- tery and the four pulmonary veins. The two large vascular masses are, in common parlance, the lungs. This whole appa- ratus, with the foetal heart suspended between it, is secured to a bony formation at the posterior portion of the auricles (the dorsal vertebra), by means of reduplications of endo-cardial lining called the pleurae, enlarging the lesson taught in the formation of the valves of the foetal organ. This endo-cardium envelops all the apparatus so as to give protection and strong- est possible support to the delicate mechanism, to ward off the rude force to which animal life is habitually exposed. At the same time the huge auricles are being built, there is vast design of most curious construction immediately adjacent and contiguous to them, moving at an equal ratio of evolution, yet more complicated in internal mechanisms, in numbers and varieties far exceeding anything to be seen within the auricles. The external configuration is that of the primitive ventricle. The curious looking objects are fastened and secured in simi- lar fashion to what is observed in the auricles. The endo-car- dium sends out vast projections and reduplications sufficient to embrace every article and piece of the wonderful apparatus in- tended for filtration of blood constituents from articles of food, and completely elaborate it, securing them firmly in their place in the posterior wall of the ventricle, some of them being sus- pended from the arch. This endo-cardium is known as the peritoneum, and notwithstanding the extreme fatality of ex- tensive inflammation to which it is subject, the true cause of death has never been suspected : for instead of paresis of the walls of the ventricle, this deduction was made upon the foetal heart or force-pump above the real ventricle of animal life. The filtration of blood takes place into a vast series of capil- lary tubes, called the portal radicals, sufficiently descriptive for our purpose, and, like streams mountain-born, flow out of the viscera in ever-increasing streamlets, until the whole volume of blood converges in the common trunk of the portal vein. A systole of the great ventricle gently closes on this apparatus ot flexible blood tubes, assisting it through the liver capillar ries for still higher elaboration by the contrivances in its won- derful machinery, finally empties it into the great trunk of the vena cava, when another systole of the ventricle lifts it up this tube to the little force pump, the auricles assisting in the workj 59 whence it is dispatched into the pulmonic system of vessels constituting a large part of the beautiful apparatus, for filtra tion of carbonic gas generated in the blood, and the reception of the last constituent the properly elaborated blood still needs for the sustentation of life (oxygen), which is in like manner filtered from atmospheric air, introduced into the organs by means of a vast mechanism of tubes larger, if not more numer- ous, than its blood vascular apparatus. There is no escape for the refuse after oxygen filtration, but by the common route of entrance, whence it is pumped out along with the carbonic acid gas This stream, therefore, is intermitting, and called respir- ation. But the injection and ejection of air is not all this movement means, but only apart—one of the factors embraced in the act. The blood which is to be filtered of carbonic acid gas and receive a charge of oxygen gas, must flow into and complete the journey of the vascular network during the time of respiratory movement. The time occupied in transporting the blood from the great ventricle through the right side of the central force-pump, to the lungs and utmost system of radicals, is the period of full inspiration ; the time occupied in deliver ing it into the left side of the heart, is the space of time occu- pied in expiration. The four large short conduits that deliver it into the left auricle is explanation why the expiratory act may be made shorter than the inspiratory. It is not prudent to do this for long periods of time, as in blowing upon wind instruments or running. When all is ready to start the elabo- rate mechanism, Nature suddenly changes the environment If there be no error in construction, from a lost link, the beau- tiful machinery runs at once and becomes a life. If it does run it is not a life, but an incomptent abortion. Independent animal life begins on condition only, of precedent respiratory movement. It is a circulation passing the pulmonary appara- tus by the cardiac force only of the trunk itself—being a pul- sation of the heart of animal life. If there be imperfection in this mechanism, the whole intra-uterine labor is lost. When it runs after tins fashion a full and complete answer is given, how independent, animal life is maintained after amputation of the placenta. Respiration is a circulation. CHAPTER IV. THE HEART OF ANIMAL LIFE. We have made the statement that the body of animal life is a heart. It has support in the highest order of evidence known to human knowledge: being no less than that fur- nished in anatomical construction and physiological perform- ance. That the rhythmic movement of the trunk is essential to the circulation of the blood, is fully proven by the prompt arrest of the circulation in the right heart and cava trunks, simultaneously with arrest of respiratory movement. The central hsemic reservoir has not the power to pass blood on through the pulmonic reservoirs to the left side of the heart This is the office of the great auricles, and when there is im- pediment of function in them, there is impeded circulation in proportion to extent of pulmonic trouble, and vice versa. Anatomical construction remains for consideration. The comparative anatomy of the little model, and the great mechanism, is proof positive of their relationship; whilst the physiological experimentations introduced at the close of the anatomical evidence confirming the cardiac power of the trunk, is the end of argument. There is nothing further needed, nor anything remaining to be proven in this respect. To begin with the comparative anatomy, take the circumstance of the relative position of the organs, and the relation of their compartments, with the general configuration. Both are ellipsoidal, the big end up, the small end down. The relative velation of auricles and ventricles is also the same. The former are built over the latter, extending beyond them on either side, and reaching down considerable distance on the lateral aspect. In other words, the auricles form a kind of liood or cap to the ventricles, having ear pieces, which project on either side. Does not the chest sit upon the ventricle of the abdomen in similar fashion, reaching down its lateral aspects, forming the hypochondriac regions ? The upper third of the abdomen is in the chest excavation. In the mat- ter of the auricular appendages, do not the acromian pro- cesses project out in similar fashion, at the lateral aspect of the 61 auricles, perpetuating even the shape of the aural curve ? There is great fidelity of outline in the two, the model being followed in every particular. They serve to widen the upper or big end of the heart in the archetype and great organ. So far every one of the counts in the protype has had its tally in that of the trunk of animal life, score for score. Both aspirate, and both expel blood from their cavities by rhythmic move- ment. Following up the comparative anatomy, an initial interrog- atory would be : How is a heart constructed ? What its FRAME-WORK or SKELETON? It is a hol- low muscular organ, built from unyielding rings. The mus- cular bundles of the left ventricle are suspended from a strong fibrous ring that embraces the root of the aorta. The muscu- lar substance of the right ventricle is similarly disposed around the root of the pulmonary artery. Briefly stated, a heart is composed of AURICLES, VEN- TRICLES, MUSCULAR SUBSTANCE and FIBROUS RINGS. Auricles are constructed over rings; ventricles are suspended from rings, with the auricles above them, extending beyond their base of attachment. Auricles are RESERVOIRS for receception of blood, to be TRAN SPORTED TO THE ARTERIAL CIRCULATION, by rhythmic expansion and contraction, with interval of rest. Such are cardinal principles, having appropriate anatomical representation in the two organs. Where is tHe firm, unyielding ring to which the muscular substance of the great ventricle is fastened? Answer:-Around the lower chest margin, composed of costal bones and cartil- ages It is a solid osteo-cartilagenous sill or beam. Upon this great analogue God Almighty has founded the temple of animal life. The manner of the curving of this great ring on either side of the ziphoid cartilage, subserves a most useful purpose in chest diastole, also allowing for respi- ratory compensation in regional disease ; at the same time per- mitting such insertion of the costal cartilages and diaphragm as would result in flaring the chest, and give spring and elas- ticity to respiratory movement. This matter has careful consideration when treating of the mode of insertion of the diaphragm and the mechanism of respiration. The muscular -substance of the great ventricle is suspended from this bony ring, and embraces a bony basin at its apex 62 below. The conical apex to this great ventricle lias much marble in its composition, to subserve essential needs in the independent animal. The pelvis is a marble vault built within the apex of the ventricle for the purpose of holding the waste products of blood manufacture in the mechanisms above, as bran from wheat in a merchant mill, fecal matter represent- ing bran, whilst blood represents flour. The excavation is so deep in order to hold the waste products of ten, twelve, or fif- teen hours, collecting during this time in rectal and urinal closets. The problem in the sacral promontory is now* of easy solution. The vault is pushed or bent backward that the per- pendicular axis may have removal from the perpendicular axis of the great ventricle, falling against the umbilical territory instead of striking the middle of the diaphragm. If this were not done, every time he laughed, or coughed, or sung, or made explosive sound, man would have the contents of the closets escaping in his clothes. In the woman with a small sacral promontory the urine often suffers such escape, the sphincter vesicse not being sufficient to resist the expulsive force above, transmitted from the great ventricle. Man must bend his body forward in order to make adjustment for the bend in the prom- ontory when inclination take him to empty the closets. This is the reason man is the only animal with a sacral promontory. He carries his great heart erect, and in consequence of such change in the position of the ventricle, vital mechanisms must suffer modification, so that when the ventricle contracts in the systole, constringing force sweeps over the pelvic plane, leav- ing the contents of the pelvic excavation undisturbed. The small intestines, suspended by powerful ligament of endo-car- dial lining called the mesentery, sweep over this plane with every contraction of the ventricle, unless specially directed upon the contents of the excavation, when the intestines are crowded and packed into it with greater or less force as occa- sion may require The muscular movement of this great or- gan is subject to voluntary power. More of this presently. The hinder or inferior extremities are adjusted to deep de- pressions (acetabula) on the sides of the vault, The object be- ing to enable the animal to move to a convenient spot for feeding or for emptying his closets, which he does according to his habits and elevation in the scale of vital evolution. The highest types of the highest forms elect a china or marble-like basin, similar to his own in water-closets, into which his excre- metns are discharged and pass out of sight with all the stench 63 they have, whilst in savagery the individual goes behind his house and performs it upon the ground in an open common, under the public gaze if not admiration. Among quadrupeds there is also difference in this respect. Cows are quite indiffer- ent; cats and dogs are very particular, keeping their little household free of all excrement, especially if of the higher types of the species. So much for the points of semblance in the anatomical frame work or skeleton of the greater and lesser cardiac organs. To complete the comparative anatomy vital mechanics will have to be applied to the disposition of their relative muscular struc- ture. Muscular substance in the archetype is arranged in cir- cular and spiral layers, being the most effective manner for the disposal of muscular force to secure simultaneous shorten- ing of both longitudinal and transverse diameters. Upon su- perficial examination, the longitudinal greatly diminishes, whilst the transverse diameter seems to lengthen during the systole. This is, however, the result of thickened muscular substance, and not at the expense of ventricular area, since its transverse axis is undoubtedly shortened in an equal ratio with the longitudinal; otherwise the effort of the ventricle to empty itself would be abortive. How are the muscles of the great ventricle disposed so as to similarly qualify it to perform its ap- propriate labor? Answer:—The disposition of its muscular force is perfect. To economize time, as also to render the la- bor of description more effective, attention is directed to the following wood cuts in Mr. Quain’s Anatomical Plates : Plate 27, page 51, Figs. 1, 2, 3, 4, 5, showing the position of the dia- phragm and cavity of the ventricle. The following wood cuts, in Mr. Wilson, Fig. 114, and Mr. Gray, Fig. 160, and Plates 26 and 40, Mr. Quain, are exhibit of the chief muscular substance in the walls of the great auri- cles. The manner muscular substance of the auricles is disposed upon the walls of these organs, and the mode of motion in them will be fully considered after treating of the ventricle, it being necessary to do so for full appreciation of auricular move- ment, which is propagated from the ventricular side. The matter is therefore delayed for the present, for more correct interpretation from a higher point of observation. We reverse the outlook upon respiration, regarding it from below, looking through the eye-piece of the telescope, which is the proper method; the other is the objective end of the instru- 64 ment. The fashion has been to look into the big end down- ward. Life is the loftiest object in the firmament of science, hence the intellect should make use of the eve-piece, and it will see more of life’s mysteries and life’s expanse. The diaphragm is ballooned high in the chest excavation, formed by the bony frame-work of the ribs, with the dorsal column behind and the sternum in front. Upon the right side its elevation corresponds to the fifth rib in front; on the oppo- site side it is about one inch lower, corresponding with the sixth rib. The periphery of the diaphragm is firmly fastened around the entire inferior margin of the chest-walls, terminat- ing posteriorly in two powerful cables, (crura,) securely an- chored to to the lumbar vertebrae. The interval between the twelfth rib and the lumbar vertebrae is spanned by two large loops of transversalis fascia, the ligamentum arcuatum exter- num and internum. They bridge over the substance of the quadratus lumborum and psoae muscles. Muscular fibres in the diaphragm extend from the ring up- ward perpendicularly. When they contract the arch or vault of the organ must necessarily approach the plane of the ring. In other words, this great muscular leaflet makes attempt to straighten out its curve upon the plane of attachment in the costal ring, moving toward this plane during inspiration. Attention is called to Plate 26, Quain’s Anatomical Plates, showing the posterior wall of the ventricle The posterior wall is built up by the two quadrati lumborum, one on either side, and the two psoae muscles. The former are securely fastened above along the entire extent of the inferior rib, firmly holding this portion of the ring; their inferior attachment being into several transverse processes of the lumbar vertebrae, the ilio- lumbar ligament, and the posterior portion of the crest of the ilium. The two psoae muscles, one on either side of the spinal column, complete this portion of the muscular envelope. They do important service in progression, passing out under Poupart’s ligament for insertion into the former. The limb is advanced under the trunk by its contraction in quadrupeds. In bipeds the thigh is flexed upon the abdomen, but the action is the same as in the former; it simply shortens the distance between the points of attachment in the lumbar vertebrae and thigh bone. Attention is now directed to Fig. 117, System Human An- atomy, by Erasmus Wilson, M. I).; also, Mr Grey, Page 285, Fig. 165, and to Plate 24, Mr. Quain. 65 The transversales muscles are now in place, and complete this lay'er of the muscular envelope or inner wall of the ven- tricle. Notice their extensive attachments and the disposition of their fibres: they form the circular muscular substance of the ventricle. When these contract they shorten the transverse axis. Their upper insertion is by muscular inter-digitations, with those of the diaphragm, along the entire border of the inferior ribs on the inner aspect of the costal ring, the other points of insertion of the muscular substance of the lat- eral walls being upon the external aspect of the ring. The rectus abdominis on either side of the mesial line secure this portion of the ring against sudden traction made upon it, as in blowing or in singing or in efforts made in climbing, lifting the body by the upper extremities. In any of these exercises, these muscles become rigid in the necessary labor to hold down the ring. For the more effectual performance of this office, their upper extremities are divided into three muscular bun- dles, to secure the widest possible insertion over the surface of the central portion of the ring: being into the 5th, 6th and 7th costal cartilages. The inferior extremities of the recti are fastened into the pubic bone. Attention is called to figure 164, Mr. Gray’s Anatomy; and plate 23, Mr. Quain’s Ana- tomical Plates, showing the middle muscular layer of the ven- tricle. The internal obliques are now in place. We feel it to he unnecessary to give the minute anatomy in description of the ventricle, the object being only to show the disposition of the muscular layers. It does not require tiresome detail of the fasciae leaflets, serving, as they do, to afford firm attachment to muscular bundles. This is the office of works on descrip- tive anatomy. When the muscular fibres of the internal ob- liques contract, the result will be (from their insertion into the lateral and anterior portions of the ring) to draw this portion downward and backward, toward the iliac crest, being the point of origin for its powerful muscular bundles; by reason of their fibrous apponeurosis covering the central portions of the ventricle, its transverse axis will be proportionately af- ffected, thereby augmenting the power of the transversales. Attention is directed to Fig. 163, Mr. Gray, and to Plate 21 and 22, Mr. Quain’s Anatomical Plates, completing the cor- tical layers of the trunk. These pictures represent the entire muscular envelope of the heart. We would have preferred a picture representing the muscular substance of the ventricle, by itself, but defer it to another time, when one may be made. Firm contraction of the muscular substance in the external ob- liques would have the effect of drawing down and approxi- mating the posterior half of the ring toward the pelvic basin, bending the body forward, shortening the long axis, and greatly reducing the area of the ventricle. This completes the muscular arrangement in the ventricular walls for the performance of systolic action. The nervous supply is from the spinal cord, from the third cervical to the twelfth dorsal or intercostal nerves. The manner of arrangement of the muscular substance over the cardiac wall, occasions a systole of the ventricle synchro- nously, with diastole of the auricles. It can not possibly do otherwise, from the nature of the mechanism, as will be pres- ently shown. The question is one purely of leverage, and not of difference of muscular substance or of nerve-supply. Muscular behavior is uniform under a given amount of nervous force. The common nervous supply to auricles and ventricle, is by the intercostal nerves. An electric current passing over these nerves, condenses muscular substance upon the walls of the chest and abdomen at the same instant. It can not be otherwise; they extend through the intercostal spaces to the walls of the abdomen, the ribs being the rods of support to the wires, (or of the muscular substance in which they are imbedded), and conduct them- to the muscular substance of the abdomen. An electric current is therefore felt upon all this territory at one time. So, then, the matter may be very readily understood, how one region may contract and another dilate, if suitable ar- rangement be made in adjustment of the leverage, the mus- cular energy being the same in both localities, according to quantity of muscular substance—being more energetic where it is more abundant. The base of the ventricle (diaphragm) has first connexion with the cord, tapping the main line through the phrenic wires, in the upper cervical region. This is the reason respiratory movement begins in the diaphragm, and has gradual exten- sion over the outer vTalls. It is also reason for the manner respiratory movement may sutler modification by voluntary power ; and why eating, singing, talking, screaming and laugh- ing may he performed at will — explosive force having direc- tion toward the outlets of the body through modification of muscular movement in the walls of the ventricle. 67 Were it not for voluntary control over the great cardiac pulsations, such vital phenomena would never happen, nor animal life continue. The animal can not pass substances down the oesophagus unless it had the power to relax the ven- tricle, that they may drop into it, when peristaltic action passes them to the cardiac orifice; articles are not put into a fist or closed hand, but into an open one. The ventricle opens during deg- lutition, and when the animal swallows, respiratory movement must halt peremptorily. This is the explanation of relaxation of the diaphragm, with circular movement of the oesophagus, after section of the pnemogastrics with irritation of the prox- imal end of superior laryngeal nerve. Apoplectics starve. Animals survive eight to ten day’s star- vation. This class of patients survive this long, if the cerebral hemorrhage be not sufficient to destroy life in the earlier stages. Heath by starvation is a common termination of this kind of injury. MUSCULAR MOVEMENT IN THE WALLS OF THE VENTRICLE. In order to bring out in relief the muscular power and func- tion of the great ventricle, and thereby effect a clear mental picture of cardiac movement, description of its powerful mus- cular envelope will be given in detail, beginning with the fundus formed by the incurvated diaphragm. THE DIAPHRAGM. Muscular energy in the ventricle, is the chief force to respi- ratory function—therefore the point of great activity — for there is such pivotal point to respiratory energy. The force of respiration is focused upon the muscular floor of the chest, the culmination of its energy being in the powerful vibratory movement of this most remarkable organ. And for proper appreciation of its performances, it is absolutely essential that we have before us the bony skeleton of the chest-walls, to ob- serve the mode of their construction and the manner the dia- phragm is fastened into them. The mechanism is beautiful in the extreme, and worthy the best effort of the intellect for that high appreciation it so well deserves. Study the mode of construction of the ribs, with cartilagenous fastenings in front, 68 combining strength with elasticity, where bone alone would be inflexible and hurtful: as, also, the degree of costal incli- nation to the dorsal column, and the very firm mode of fasten- ing at this point, giving great solidity to the respiratory skel- eton. After observing all this mecanism critically, make equal careful inspection of the manner the diaphragm is ballooned into it, and the points of its fastenings ; also, the general rela- tion of the two, with the object of forming an intelligent opinion as to the probable result of diaphragmatic movement upon this position, and the kind of motion it would impart to the costal frame-work. For it is the manner of ascent nature makes to the mammalian elevation, and solution of the prob- lem of respiration in them. Look at Fig. 5, Plate 27, Mr. Quain’s Anatomical Plates. The inclination of the costal bones is below the horizontal line of the dorsal perpendicular, progressively increasing from the fifth costal bone down, each one of these representing the horizontal leg of a distinct dorsal triangle. On the other hand, the seven ribs on either side undergo progressive retrench- ment, till in tne twelfth, the shortening becomes so great the bone does not measure one-half the length of the last true rib. This shortening takes place upon a line extending from the third lumbar vertebrae to the lower portion of the sternum. This oblique line is represented by the elastic beam of carti lagenous substance, which receives the ends of the costal car- tilages, holding them fast in their places, at regular intervals. The interval between the costal hones is occupied by two lay- ers of short, muscular fibres, that cross each other at an acute angle, known as the “ external ” and “ internal ” intercostal muscles — the intercostal arteries and nerves running between them. The diaphragm acts upon this cartilaginous beam from the inside, when it begins its descent, the vicera pressing against it under about four hundred square inches of atmospheric pressure; this is to be overcome before a vacuum area can be formed at the base of the lungs. By reason of its high bal- loonment, it exerts great traction force in pulling itself out of the chest-excavation, which is felt upon the ends of the seven inferior ribs. The utility of this arrangement is two-fold. 1st. By pulling upon the long axis of the costal bones, traction force has greater solidity than if it pulled transversely against the intercostal muscles. 2d. By pulling against the ends of the costal bones, it bends them, and flares them open at the sides and middle—being arched and elastic. Their elasticity is in- 69 creased, at the terminal extremity in front, by cartilaginous splicing, extending from them to the cartilaginous beam or ring of the ventricle. If one pull upon the end of a flexible bow with suflicient force it is bound to spring at the more flex- ible portion, first, extending to other firmer portions, with in- crease of the energy. This is the explanation of respiratory movement. The manner of costal articulation with the dorsal vertebrae is such that when the hones undergo the bending of inspiratory movement, they are rolled outward and upward. In other words, the manner the diaphragm pulls against their extremities causes the ribs to twist upon their long axis, at the same time increasing their curvature and occasioning the widest possible expansion at the lower lung regions, corres- ponding with their base. By such arrangement respiratory movement is made elastic, and being operated from below, necessity does not exist for muscular substance upon the chest walls for respiratory pur- poses ; a fact we propose to prove by physiological experiment- ation of dissecting off the external chest muscles, leaving res- piratory movement unimpaired. When the flaring takes place by bending of the bony arches, the inter-costals regulate the distances or intervals between the costal bones. But on special occasion muscular substance upon the chest can be made operative to a degree for chest expansion, as will be shown later on, and the manner it is done. The curving of the cartilaginous ring in front, on either side of the ziphoid cartilage, leaving a V shaped interval, is provis- ion for extension of the costal bows when the diaphragm re- laxes. Interest in the latter organ is not diminished by com- parison with the device of the costal mechanism in which it works and performs such great role in life’s drama. Its shape is ovoidal, and for the purposes of description is resolvable into three leaflets; the central or cordiform one, though small as compared with the one on either side, is nev- ertheless the point of greatest interest. The pericardium is fastened to this portion, whilst the aorta, vena cava, and oesophagus pass through its territory. If a flatish apple be held by the stem, and a section one- eighth of an inch thick be made through it on either side, the slice will not be bad imitation of the diaphragm. The core and seed pocket represent the cordiform territory, with its heart and pericardium ; the terminal blossom and the sides represent the crura and the lateral leaflets. Lite’s form grows out of 70 this seed- bed. The diaphragm sustains the relation of constituting the oscillating floor to the respiratory apparatus, at the same time forming the vibrating ceiling to the abdomen or great ventricle, whose viscera under atmospheric pressure carry it high up into the chest excavation, where it is found after death, tense from distention. The effect of contraction is to momen- tarily withdraw itself from the depths to which it had been car- ried, coming nearer the lower chest line. This act constitutes INSPIRATION. Its relaxation and retreat under atmospher- ic pressure, into the deeper chest regions again, constitutes EXPIRATION. The sudden lowering of the pleural floor in the former, produces the pulmonic vacuum, whilst the com- pression force of the latter aids in expressing out the air again through the same roadway by which it had rushed into the vacuum areas. This, with a little flaring movement of the lower ribs, is the whole extra pulmonic performance in ordi- nary respiration; the movement taking place in the lateral walls of the ventricle, having reference to the vascular appara- tus of the abdomen chiefly, though contributing an item in the firmer fixation of the costal ring, even in this quiet form of respiratory movement. The more energetic action in the ab- dominal walls occurs during active movements of the animal; when blood must be dismissed rapidly out of the great ventri- cle, respiratory movement has proportionate increase. The pleurae occupy the whole upper surface and sides down to the point of insertion into the costal ring, with exception of the pericardial territory. It follows that in the act of withdrawal of the diaphragm during inspiration, the BASE of the lungs is included in the vacuum. This is quite enough for ordinary respiration, The central portion of the diaphragm, or middle leaflet, has less muscular fringe than the right and left leaflets, and in con- sequence, this cordiform territory is comparatively quiet. The reason for such arrangement is to save cardiac oscillation, since the pericardium being firmly fastened to it and to the arterial mains above, traction force would be immediately felt in a car- diac jerk, the anterior and posterior fastenings of the pericar- dium not being sufficient to prevent it. The ascending cava takes advantage of this eddy in the undulating plane to effect entrance to the pericardium and right auricle. The character of this venous lumen is worthy of notice; it differs so notably from the oesophageal opening several inches to the left of it. It is a permanent and nearly circular lumen, 71 destitute of muscular fibre; whereas, the latter is an ellipse, formed of strong muscular bundles, which must inevitably con- stringe the oesophagus in powerful movements of the organ, as in. running and jumping, screaming and laughter, when it is highly probable an important office is to aid the sphincter muscle of the cardiac orifice to retain the ingesta. The same mus- cular bundles embrace the aorta trunk between their tendons before insertion into the lumbar vertebrae and compress it with every inspiratory movement, as I have repeatedly demonstra- ted bv physiological experimentations, some of which are re- ported further on. The permanent vena cava opening, as also the permanent hepatic openings into the cava trunk, are to facilitate onward movement of the blood, occasioned by the great cardiac pul- sation. The gall bladder is subject to pressure also, and the juice expressed through its discharging duct into the duode- num. If movement of the ventricle be arrested it becomes enormously distended in twenty-four hours, as I have proven experimentally over and over again. For full appreciation of the perfection of the muscular ap- paratus of the abdominal excavation, a cat should be chloro- formized and a section taken out of the adjacent abdominal walls and costal ring, including a portion of the diaphragm. When the peritoneal surface is exposed, one cannot for the life of him tell where the line of distinction is between the trans- versalis muscle and the diaphragm ; and only by closely fol- lowing separate muscular fibres with some pains-taking can it be done at all, the whole matter having such strong semblance to the walls of a continuous muscular ventricle. The dia- phragm acts as a great detrusor muscle of the abdomen in ex- pulsive effort. When the systole is fully organized by corres- ponding movement in the lateral walls, the pelvic excavation is filled to repletion by the movable viscera forced into it, (the small intestines and omentum); and what collection there may be in the bladder, in the rectum, and in the womb, will be subject to a great amount of pressure, and may be driven out of the body even against one’s will, for the sphincters may yield under the force'. Its habitual participation in the act of defecation is in the common experience. Its effectiveness in the later stages of parturition one should not deny who would have his opinion respected. A most important circumstance, not hitherto noticed, is COMPRESSION of the aorta trunk AT THE CRURAL 72 OPENING during each inspiratory act, the degree of compres- sion force having regulation hy the energy of diaphragmatic contraction. When inspiration is deepest it is greatest, and vice versa. The right crus forms an arc or bow over the ar- tery, and when the muscular bundles shorten during inspira- tion, the bow straightens out between its extremities or points of attachment, pushing the vessel in consequence AGAINST THE OPPOSITE CRUS. Fig. 4 is a photograph of the diaphragm, from Mr. Gray. For experiment let a ruler be placed so as to rest upon the up- per origin of the right crus, at the tendinous center, and upon its point of insertion into the third lumbar vertebra. The ruler will cover up the lumen of the aorta; hence energetic contrac- tion of the muscle would have the etfect to occlude the aorta trunk. During inspiration blood comes to a rest at the crural flood-gate, whilst the heart continuing to beat as usual it accu- mulates in the upper portion of the aorta, climbing up through the internal carotids and vertebrals to their relative brain territory, passing through bony canals and supplying the nerve substance by gentlest irrigation. Brain substance (the vesicu- lar matter) is four-fifths water, and it is not capable of with- standing the thumping of arteries and the forcible injection of blood, as in the common method. Blood reaches the brain substance through long bony tunnels hy most devious passage. The cerebral circulation is unique. When its sub- stance is incised, there is no jet or spurting of blood from the divided vessels, but a constant flowing, marked hy a diminu- tion at each inspiration from sudden out-rush at the base through the wide jugular canals, which takes place at this time. Physiological experimentations are given corroborating the above. MUSCULAR MOVEMENT IN THE LATERAL WALLS OF THE VEN- TRICLE. It is with unmixed pleasure we contemplate the exalted me- chanism Nature has elaborated in this large territory of the animal organism. The wonderful perfection of a scheme hav- ing several paramount objects to he attained, where failure in one would result in common ruin, is measure of exalted ge- nius, well calculated to inspire the beholder with a feeling of awe and reverence; it may be for the first time in his life. The f-h 4 73 intricate and delicate mechanisms for the elaboration of blood, need support and protection against injurious compression ; yet, an amount of compression is absolutely essential to the systemic and portal circulations. At the same time, the in- terests of respiration must be subserved without entailing in- jury upon these functions. Moreover, suitable modification, to be made in the female, for lodgment of the fruit of the womb, in addition to the waste materials left from blood man- ufacture. All these varied interests, having appropriate mechanisms, performing without collision under one roof, in one compart- ment, the mobility of whose walls alone is fraught with peril, otter a problem in vital mechanics without rival. A ventricle containing all these mechanisms, must have construction, whose systole will not be fatal. The corner-stone of anatomi- cal construction is furnished in the principle of muscular con- traction ; when muscles contract, they shorten in the direction of their origin and insertion. Applied to the construction of the great ventricle, we observe the following arrangement of the muscular substance of its walls. The upper attachment is around the border of the inferior ribs; the lower insertion is around the pelvic rim. When contraction sets in during the systole, it would there- fore occur on a plane between said origin and insertion; the more energetic the muscular condensation, the nearer an ap- proach to a horizontal line in the plane. Compression must, therefore, take place by effort to compress the viscera within this plane. The distance between the lateral walls effected by insertion into a bony ring above and below, is estoppel of the systole, and arrest of compression from muscular force, though atmospheric pressure is still operative. The energy of this latter force is well exemplified in cases of emaciation, in which such shrinkage in the volume of the viscera takes place, as to bring them within the muscular plane of the ventricle ; when atmospheric pressure, continuing as active as ever, the plane is bent backward against the viscera, in degree with the vis- ceral shrinkage, causing that incurvated appearance under the ribs, extending to other portions of abdominal surface char- acteristic of this condition. Hunters, after a several days run, lose the abdominal rotundity with which they started, becoming lank and hollow from loss of visceral fat, given for the gene- ration of running force. Muscular energy being equal, ventricular compression is 74 most effective upon a line anterior to the plane, hence hernial protrusions result to this class of persons. The viscera are so forcibly compressed, the movable parts burst through the less protected portions of the walls, escaping at the inguinal and umbilical regions. In the female, the pelvic ring is made wider, to allow for uterine expansion ; but when she is so un- fortunate as to have a more narrow (male-like) pelvic rim, she must be habitually upon her guard during gestation, keeping as quiet as possible, more especially must energetic movement he inhibited, as in mounting stairs, since the systolic force ne- cessary to support the blood column upon the brain mass, to enable it to perform such energetic action, would endanger miscarriage. This is the secret of such accidents. The obstetrician has long acquired the habit of shaking his finger at the woman with a gi avid womb, in emphatic warning against climbing stairways. The wider the pelvic rim, however, the greater de- gree of exemption from such “ accident,” premising the ab- sence of uterine disease. But such modification of the pelvic rim, is strongest obstacle to that measure of physical energy in the lower extremities witnessed in the male, and cause of that “pain in the side,” of which she complains so much, pro- duced by traction and pressure upon terminal twigs of inter- costal nerves, located about the region of the ring; when the strong muscular substance of the ventricle suffers unusual condensation, as in deep inspiration, in “sighing,” or the still more frequently repeated traction force exerted in running; at such time, the pelvic muscles have strong tendency to flare open the upper ring, till it correspond to its own muscular plane of the pelvic circumference. If energetic movement continue after the “ stitch in the side” is felt, it will soon ex- tend all through the ring. The man with a wide pelvis can not run well, and he need not try it more than once. Women even aggravate this trouble, by bending the costal ring still further inward, by tight lacing, and compressing bands in their petticoats and outer-dress. Hence, they sigh oftener after din- ner, especially if they lead a sedentary life (sewing), which in- terferes with respiratory action : for the “ sigh ” is but compen- satory movement for restricted lung-base, whilst the greater pain endured is proper penalty exacted for violated law. Let them relax the energy of the lacings, if they would de- sire abatement of the pain. They should be more moderate in cultivating deformity. The soil to this spontaneous growth 75 in distortion, exists in male prejudice, to which the female ever panders. The Chinese woman works upon her foot; a small, deformed foot is her delight. But the Caucasian rejoices in a “small waist.” The greater mobility in the upper chest-walls, is na- ture’s compensation for the foul imprisonment of the lung- base, so long indulged, and so persistently carried out, over the 'model of artistic taste. And, since the higher types of the male species prefer the hips to appear full and round, and the feet a little larger than the Chinese woman’s, it does not appear very probable, the absurd custom of over lacing the waist with corsets, and the feet with tight-fitting shoes, will be discontinued soon. The trunk of animal life is in two great pieces: a broad upper one and a long lower piece, which telescopes the upper piece. Respiration must be viewed from below upward—the eye-piece is toward the ground. It is a GLIDING IN AND GLIDING OUT MOVEMENT, of the lower piece into the upper one, piston fashion. Respiratory movement is energized in this manner, viz.: 1. The electric current from the cord strikes the phrenic nerves, being the first given off by the trunkal line. The movement, therefore, begins in the diaphragm. 2. The electric current continuing down the cord, passes into the twelve dorsal nerves, or the twelve pairs of inter- costals, the wave-like movement extending over them from above downward, and from within outward. The twelve pairs of dorsal nerves are the common nervous supply to the chest- surface and abdominal walls. When muscular substance con- denses under them in respiratory movement, it is, therefore, simultaneous over both localities. The result is dependent upon the manner of the disposition of the muscular substance, the whole matter being one of leverage simply. The condensation over the chest-walls of muscular bundles operative for chest-expansion, causes upward traction upon the costal hones and cartilages, with upward movement as the re- sult of inspiratory act, the diaphragm being the potential cause. At the instant this is taking place, there is synchronous movement through the muscular bundles of the abdominal walls, the result of such condensation being to approximate their points of origin and insertion; they straighten out upon their plane of attachment; the diaphragm coming down all 76 the time of this lateral movement (piston-fashion,) over the mouth of the muscular barrel of the abdomen. The more en- ergetic the inspiratory movement, the greater its descent, and straighter the sides of the barrel. The diaphragm is ballooned high into the chest-excavation, in close apposition with the base of the lungs (the thickness of the pleurae intervening,) and initiates respiratory move- ment, by condensing itself upon the ring of insertion, which would remove it from the lung-base, did not their alveolae suf- fer atmospheric distension from inrush of air, in exact ratio to the downward movement, keeping the lung-substance upon the diaphragm all the time .No divorcement takes place between them. The lungs ever follow the diaphragm, and ever submit to it. Both are mu- tually inter-dependent. The problem is in formation of the vacuum. To effect this, the diaphragm must pull itself out of the deep portions of the chest, with the abdominal viscera upon its breast, opposing it, and about four hundred inches ot atmospheric pressure upon them in addition. It performs tremendous labor to accomplish this result; and if it had all to be done on the instant, it would utterly fail. On the contrary, only a portion has to be done at a time, whilst the conquered territory in the vacuum areas is as rapidly occupied by its atmospheric ally, which comes into the open province from the rear, and firmly holds what has been ac- quired by the diaphragm, keeping steady pace with its - ad- vancing lines, till all the territory is occupied, and inspiration accomplished. Still, great traction force necessarily falls upon the ring during this performance, in order to form a vacuum of small extent even, since the viscera, and several thousand pounds of atmospheric pressure must be first pried up a little way at a time. Atmospheric pressure from the lung surface is only one of occupation ; it does not more than occupy what has been taken by previous movement of the diaphragm. It simply follows it, and holds possession of what is taken in the forward movement of the force in front of it. Under cerebral stimulus, traction energy so exerted upon the ring of the ven- tricle, through the diaphragm, would be sufficient to roll it inward and upward into the chest-cavity, if provision had not been made to interdict the movement, by timely contraction of the recti, and the two pairs of oblique muscles, acting from the firm anchorage of the pelvic basin. To have some appreciation of the voluntary power in the 77 diaphragm, or rather its measure of energy under voluntary stimulus, make use of the following experiment, viz.: Place one hand upon the surface of the abdomen, and make firm pressure, with the object of ascertaining what is taking place under it, at the same time firmly compress the nares with the thumb and fore-finger of the other hand, with the ob- ject of inhibiting any ingress of air into the lungs, keeping the lips compressed against each other with the same intent. After all is ready, make strong effort to inspire. The dia- phragm makes prodigious efforts to force down the viscera, by pulling itself out of the chest cavity, hut the abdominal mus- cles are prompt to the rescue and support of the osteo-carti- laginous ring, upon which the diaphragm is pulling, opposing the upward movement with such force as to render them hard and iron-like, under the firmness of their contraction. The experiment is readily made through the clothing. Has wrong interpretation been placed upon this strong muscular move- ment ? By all means let the true one be given. What is nature attempting to perform with such expenditure of nerve- force, and muscular energy, in this locality, at this particular time ? What does animal life stand so much in need of at this juncture of its affairs? Whatever that is, will he appropriate answer to this interrogatory. But, remove the pressure from the nose and mouth, and air will rush into the vacuum, at the lung-base, instantaneously, with simultaneous abatement of muscular energy in the walls of the abdomen. Is the latter not dependent upon the former? Is the relation not one of cause arid effect ? Would the latter ever happen with the former in abeyance ? The diaphragm can make but partial descent in the absence of its ally of occupation, fur- nished in fresh pulmonic air. What other law would explain muscular energy in such degree of exaltation in the walls of the abdomen, at this special crisis in respiratory want, than the one to which reference is made ? In other words, it is the measure of diaphragmatic force, and exact ratio with it, in the hardening of the muscular substance of the lateral walls, which holds the ring. During ordinary respiration, muscular energy over the external walls of the abdomen is greatly reduced, so much not being necessary to make the needed compression upon the vascular tubing it contains, to empty their contents into the ascending cava, and express the lymphatic juice through its system of vessels. Besides, compression force must have regulation on account of the heart itself; if too 78 great, it may rupture it, else the lung capillaries, as frequently happens in racing. In normal respiration, the diaphragm gradually, but only partially, extrudes the viscera out of the chest excavation, causing them to appear under the softer abdominal walls, which being still flcired and relaxed from the previous diastole, re- ceive a wave-like motion upon the visceral approach, and are lifted up by tile strong under-current; when resistance sets in at once through all this territory, increasing every moment to completion of inspiratory movement, being greatest at its acme. Because this energy is evolved after diaphragmatic action sets in, is no reason for depreciating it, the movement being essential to later stages of lung expansion, and the cir- culation of the blood. The blood throughout all the vascular tubing, in the great cavity of the abdomen, is caught between the two contending forces in the diaphragm and abdominal walls, and driven out of this great ventricle ; the energy of the movement being dependent upon degree of vigor of the systole. That this is true, is fully borne out in cases of sudden death occurring at the height of this energy, as in running the race horse, or in overloading the draught horse. These cases do not perish from lung obstruction, from inability to expand their alveolae, with corresponding blood-delay in the right chambers of the heart; on the contrary, its vascular appara- tus is over-full of blood, and, in consequence, receives, the largest amount of areation possible, as is fully proven bv the ARTERIAL HEMORRHAGE, that takes place in the'rush- ing torrent escaping by the mouth and nostrils. The fault is not in the LIJXG - ORG ANS — their mechanism may be per- fect, and most ample — but in TOO GREAT ARRIVAL OF BLOOD. The blood can not go into the left chambers, al- ready full, nor is it permitted to return into the right heart — the semi-lunar valves interdicting. The only mode is to either burst the capillaries, else burst the heart. In obesity, or fatty metamorphosis of its muscular structure, the right ventricle is very liable to give way under this kind of strain. If it happen to the left side, dyspnoea will precede rupture of the ventricle from pulmonary blood-stasis. The too rapid delivery of blood under the powerful pressure of the great ventri- cle, may, therefore, either result in bursting one of the little ventricles above, or the lung capillaries. Venous blood from the head and neck, straight-out, as the latter are in racing, 79 could not do it, since the venous blood-column inclines to a straight line with the heart. The heart is broken by injection from behind, from which there is no escape. The blood in the portal veins and in the eava-trunk, in racing, is subject to great pressure. The abdomen forms a muscular barrel, with projecting ends, the lower one comprising the pelvic basin, the larger upper one extending into the chest, and covered by the diaphragm, which is fastened around its rim. The sides are flexible and yielding, with a stiff section in it, represented by the spine. It is con- stantly full, but alters its area by rhythmic contraction and expansion. During diastole, it is greatest, at which time the arch of the diaphragm is at its highest elevation in the chest cavity. When the upper piece, or incurvated head, be- gins to condense itself and straighten out horizontally over the head-line or rim, it forces the subjacent viscera down into the barrel, the sides of which, feeling the stimulus, begin at once to condense themselves also, and, under the combined pres- sure of this augmenting force — which is greatest at the height of inspiration—the contained fluids in the vascular apparatus, including the lymphatic juice, escape through the diaphragm, the glandular organs discharging their contents at the same time: a circumstance readily proven by physiologi- cal experimentation of dividing the walls crucially, else para- lyzing them by destruction of the spinal marrow as high as the sixth dorsal vertebra ; in which event, there is arrest of urinary secretion, whilst the gall bladder is full to bursting within twenty-four hours, the space of time the animal may survive. There can be no mistake in this matter. The diaphragm descends upon, and acts as a piston in a muscular well, which narrows on its approach, to confine the contents, and pre- vent escape of fluids in any other direction than that through the piston and secretory outlets. Hence, w7hen the diaphragm b down nearly upon the top of the well, as in energetic inspiration, its plane is nearly kew - to the muscular plane of the well. A section would, therefore, represent the letter L, inverted. The mistake of interpretation of muscular behavior in re- spiratory movement of the abdomen, is mainly attributable to the earlier portions of the inspiratory act; at this time the muscu- lar barrel is relaxed, and the piston of the diaphragm coming down just after this relaxation of diastole has taken place, causes a wave-like movement, sight entirely being lost of the 80 instantaneous contraction setting in over the crest of the wave, hearing it down and holding it so it go no further, which is caused by the barrel straightening its sides. I have seen this performance go on with the left side of the chest opened so as to expose the incurvated piston of the dia- phragm, descending as if to go into the barrel, then stop and come back again, having finished the movement of inspira- tion. Have seen it repeat this performance again and again ; moreover, had the animal to revive, with the left lung col- lapsed, and the heart exposed. The diaphragm, therefore, went down toward the mouth of the muscular barrel as its own act, and part of the respiratory performance, to meet re- sponse and co-helpers in the full act later in the performance of life’s drama of respiration. If this last actor fail, there is speedy end of respiration and of life. Death results from anaemia of the brain, from non-arrival of blood out of the great ventricle. The co-ordination of movement in the per- pendicular walls of the ventricle, with that of the diaphragm, has confirmation by physiological experimentation, corrobora- ting the auto-physiological experimentation of the aborted re- spiration, advised above. There are several methods of doing this, which are quite satisfactory in their results, placing the matter beyond controversy; not leaving room for doubt. Vivi- section settles it. The object being, of course, to see whether blood will con- tinue to accumulate in the ventricle, till the animal perish from cerebral anaemia, in consequence of such blood-diversion. It is no small circumstance, that after these operations, the an- imal keeps perfectly quiet, and all the great activities in abey- ance ; since it is especially for their performance great energy is needed in the ventricle, to keep the arterial circulation full, especially that of the brain-substance. "Whereas, in the very quiet condition of torpor, no such tension exists. Nevertheless, the animal can not save its life, and it dies of cerebral amemia. from blood-diversion in the vascular appa- ratus in the great ventricle, the requisite force not being pre- sent to expel it. The piston of the diaphragm acts as usual, moving even more energetically; but the muscular barrel is now only a bag, passive, unresisting, no longer opposing the downward movement; and the contained juices ooze out and around in every direction. At death from extensive peritonitis, the per- itoneal sac is full of hiemic juice; whilst the systemic vessels 81 are nearly empty; the blood diversion being gradual life con- tinues until the general anaemia is complete. Had paresis of the muscular walls been less gradual, death would have had corresponding acceleration, with less amount of oozing; the vessels containing sufficient blood to destroy life before much oozing can take place. If the ventricle be divided crucially by an incision extending from the middle of the quadratus lumborum to a correspond- ing point on the opposite side, and one from the ziphoid car- tilage to the pubes, death speedily follows; taking place in some instances in a few minutes, in others life continues for an hour or such matter, the time varying somewhat. Death results from anaemia of the brain, the blood having accumulated below the diaphragm. With this revelation many unexplained circumstances in clinical experience, embracing some in physiology and anato- my, have ready explanation given them. Syncope following paracentesis abdominis, or from parturition, is due to sudden loss of support to the blood column in this great cavity, the re- laxed abdominal wall not having had time to condense them- selves after removal of the contents which had distended them. The operation of ovariotomy does not disprove the ventricular character of the abdomen, as no muscles are divided, the recti being only separated to a limited extent. The patient is care- fully bound up with bandage and padded with cotton wool. In this class of cases death is more rapid than in ordinary per- itonitis, by reason of traumatic injury to the great nerve plexuses, with resulting vascular paralysis which it occasions, and consequent more rapid withdrawal of blood from the sys- temic circulation. The rupture of adhesions over the parietal surface are comparatively free of danger, but it is far otherwise with those over the viscera, for this is the territory of the sym- pathetic centres. It may be very readily understood how extensive adhesions may be broken up in the one case with speedy recovery, whilst in the other but limited adhesions are fraught with peril. In the latter it is far preferable to leave the adherent portions of the sac undisturbed, by cutting them out of the latter with scis- sors. The term septicaemia is no explanation of the mode ot death following ovariotomy, further than the irritation fetid exudations may occasion to the sympathetic ganglionic centres, when it overflows them ; for this reason good drainage cannot be lauded too much. These patients all die alike, the unfavor- 82 able issue being sooner reached in some than in others, from more rapid extension of the vascular paresis in this greatest cavity of the body. Shock following this operation is brain anaemia from vascular engorgement of this territory. It is also of ready appreciation why there is such staining of the inner portion of the thighs, extending over the inguinal and lumbar regions in fatal cases of peritonitis; being due to venous stasis, since the ventricle is paralyzed and no longer aspirates blood from these localities. The lungs do not aspirate blood from the lower extremities, for after abdominal paralysis from de- struction of the spinal medulla over the lower portions, blood accumulates in these localities, notwithstanding the unusual energy of the diaphragm it stimulates as physiological compen- sation for paresis of the lateral walls of the ventricle. It is also of easy solution why there is a gush of uterine blood at each effort to cough, in cases of hemorrhage from this lo- cality ; there is violent systole of the ventricle at this time, with unusual energy over the apex where the womb resides, compressing the dilated organ. The singular anatomical circumstance of the absence of valves in the venous circulation of the abdominal cavity, so long unaccounted for, receives ready explanation also. No valves are needed inside of a ventricle save at the point of in- gress of blood to inhibit reflux during the application of com- pression force. The femoral and iliac veins have such valves. And the great mystery of the portal circulation has final ex- piation, as also that of the lymphatic system; especially'that portion of it through the devious course of the mesentery, with its rows of glands emptying finally into the receptaculum chyli. THE MANNER OF EXPULSIVE MOVEMENT IN THE VENTRICLE. This may occur in one of two directions representing the terminal extremities of the trunk, i. e. through the chest re- gion, as in coughing, screaming, harking and vomiting; else through the pelvic excavation, as in defecating, urinating, ten- esmus and parturition. Some of these acts are voluntary, oth- ers involuntary. Coughing and vomiting are involuntary; so is tenesmus. In the act of coughing the lungs are driven with great force into the upper chest regions, the greatest violence falling upon the apex, from its being driven against the upper ribs. The broad base resting upon the diaphragm distributes concussion force, so that no one portion is unduly strained; 88 but it is not the case with the conical apex, which receives the whole force of the impetus from below in an impact against the unyielding bony walls which it occasions. This is the rea- son tubercle elects the upper portion of the lungs in preference to any other. When a scrofulous subject contracts a cough the violence it occasions to the lung apices is followed by cheesy exudation products; it is simply scrofulous inflammation fol- lowing the injury to the alveolae. This class of persons should guard themselves against lung concussion, as coughing, singing and screaming with violence. Many a case of phthisis begins from one of these lung exercises. And this is explanation of the clinical circumstance pointed out by Laennec and Louis of exemption of emphysematous lungs from invasion of tuber- cle, since it proves the absence of scrofula in them, as the alve- olar lesions would have had cheesy inflammation products to follow as a natural consequence of their injury. The pulmonic explosion is the result of a sudden let-go, or relaxation of the diaphragm after deep descent, and the quick surging of the viscera under atmospheric pressure, against the base of the lungs, assisted by energetic action of the obliques, and especially of the transversales. If the party be thin in flesh the spine itself is tightly embraced by the energy of the contracting force. Being under voluntary control, the ventricle can be so tightly constricted from below as to empty this portion into the chest excavation, causing the walls to retreat backward upon the spinal region, whilst the hypochondriac sections flare out from visceral impaction. If effort be made to draw down the diaphragm in this condition the flaring becomes still greater, when the ring of cartilage straightens more and more from enormous distention force. Young subjects, having flex- ible walls, can do this readily enough; but middle-aged per- sons, especially corpulent ones, cannot succeed entirely. They have more abdominal contents than will fill the excavation ; the chest walls besides are more rigid in them. When explosive energy is directed upon the pelvic organs, the body is bent forward by lumbar flexure till the long axis of the ventricle is made to correspond with the perpendicular axis of the pelvis; when the diaphragm begins its descent, pushing the viscera before it, and those immediately over the basin, (the cluster of intestinal loops suspended by the mes- entery with the pendant omental covering.) These movable parts fill the basin to overflowing, when the obliques and tran- 84 versales transmitting the motor wave from above downward, the diaphragm holding its own, the viscera are packed with great force into the pelvic excavation; compression force being great- est upon the uterus, the bladder and the rectum, since they are at the bottom of the bony vault. These.several organs have a complement of muscular force, but need the assistance of the greater force above to expedite expulsion of their contents. The two forces added together in parturition are formidable, and at times even terrific. MUSCULAR MOVEMENT IN THE WALLS OF THE AURICLES. Muscular substance upon the chest walls is not disposed in such manner as to obtain its full force in chest diastole. The muscular bundles are quite oblique, falling away from the per- pendicular axis of the body, having reference more to the uses of the upper extremity than to subserve respiratory purposes. The great serrati and pectorals do not run above a line of thirty degrees, most of the bundles tailing below this plane, ap- proaching or corresponding with the transverse axis of the body, thereby losing most all their power of drawing up or elevating the ribs. To effect this they should have inclination in the op- posite direction, or toward the longitudinal axis. On the other hand, their point of attachment to operate the chest walls is on a most unstable bone, (scapula,) which rocks with every move- ment of the arm. Even in walking there is much rocking of this bone, indicated by the motion of the dress. The scapulae of school girls are as nimble as kittens; and the muscular sub- stance winch swings them to the trunk is designed to secure such great mobility for special purposes of the arm and shoul- der. The clavicle acts as a flag-staff in swinging the arm out from the body, allowing it to swing free of the trunk ; but if accident break the clavicle, the arm falls against the side as a wet rag, useless and helpless. The base of the skull and spin- ous processes of the cervical vertebrae, suspend this flag-staff by the long ropes of the trapezius and sterno-cleido-mastoideus muscles. This and moving the head is their chief oflice. They support the shoulder and the arm. What of the serra- tus and great pectoral ? When the arm swings free at the side they are relaxed, and not in a position to perform any move- ment upon the chest walls to effect inspiration. Moreover, the serrati are obviously enough for quite other purpose, being no less important than that of supporting the entire weight of 85 the front portion of the body in the quadruped, which swings free of the ground between their broad and powerful muscu- lar bundles. They are made so wide, to cover nearly the whole chest, having insertion into the entire base of the scap- ula, that they may form the broad swing in which the trunk is rocked as the animal moves along. They enable man to lean upon his hands, or elbows, or to push with force against resist- ing obstacles. The asthmatic acquires the habit of leaning upon his elbows, as in this position he pushes the scapulae back, putting the great serrati upon the stretch, and thus making them operative upon the chest wall, which he wishes to help out of the way of lung expansion, since otherwise the lungs would have to lift them up. But this kind of respiration is extremely awkward and abnormal. Moreover, what other mode remains for putting the serrati upon the stretch ? What sort of firm fastening do the scapulae have to effect this ? The spinous processes are not strong at best, whilst the thin ribbons of the rli mboiclii, and the long fibres of the transverse por- tions of the trapezius of either side, extending all the distance to the scapular spine, is the weakest and most ineffective me- chanical contrivance Nature could adopt to secure that firm support needed for moving the chest wall. Nature is no bung- ler, and it is a false position to place her in. The muscles of the chest are the analogue to those of the pelvic basin ; they have reference to the adjacent extremity, with secondary ac- tion upon the trunk itself, moving ALL OF IT, not a portion only. And if firmness of support is measure of traction force to be exerted upon it in respiratory movement, the problem is not of difficult solution where to find the pivotal point. If not in the strong pelvic mechanism, where is it to be found ? If the chest walls are to be lifted by the two long muscular ribbons on either side of the neck, it is of ready solution how much work they must do. There is something like three thousand pounds of atmospheric pressure upon the chest to be overcome—not all at once, but a little at a time—that a vacu- um of any extent may be formed. Would it not be imprudent to throw* a great weight sixteen tim 33 a minute upon the cer- vical vertebrae? Nature does not lose judgment at this point of the circulation. She would not endanger the spinal cord, or the spine itself, in the effort to expand the great heart of ani- mal life. In all due deference to medical opinion, muscular substance upon the chest walls is for other purpose than chest expansion, 86 which is of onlv limited extent and of secondary importance ; the chief one "being to SUPPORT THE BODY AND TO OBTAIN SUPPLIES. The great pectorals are for embrac- ing, climbing, and lifting the body ; their extensive points of origin over the front and sides of the chest and ring of the great ventricle, eminently qualifying them for these purposes by strongest possible support; their insertion is into the ante- rior bicipital ridge of the humerus. With such insertion how can they he effective for lung expansion in ordinary respira- tion, since they lie loose upon the chest when not specially oc- cupied, by reason of approximation of their points of origin and insertion? In extraordinary respiration, when the elbows are fixed, or the arms are extended above the head, the hands clasping a railing or bed-post, as in the worst forms of diph- theria, some of the muscular bundles inserted into the mova- ble ribs, and not into the immovable ring of the ventricle, or the sternum, may be effective in chest diastole. They are op- erative in inspiration, receiving much assistance from the small pectorals, whose origin and insertion qualify them to perform regular labor upon respiratory functions. These are potential muscles in respiratory compensation for restricted lung base in the female. Wliat other muscles remain for consideration in this locality? The subclavius, short intercostals and levatores anguli costa- rum, near the dorsal articulations, inclusive of the small scalenii with which they have associate function in deep inspiration, as also the little serrati. How much work do they perform ? Upon this strong anatomical evidence, and muscular law, we therefore reiterate the statement that lung expansion is not ef- fected through the muscular apparatus of the chest , but that of the abdominal territory. An autophysiological experimenta- tion confirming this statement is that ot aborted inspiration spoken of above. The hand removed from the abdomen where muscular energy is most violent, and placed upon the UPPER chest region discovers only slight movement in these ribs. The diaphragm moves the others; hence the lower ribs are the more active ones. This would account for the more rapid dis- tention of the lower lobes, and the more gradual filling up of the upper ones after the lower ones are filled, toward the end of inspiration, and FULL ONLY AT THE END OF THE DEEPEST INSPIRATION. Hence, in ordinary respiration, the lower lobes are the more active portions, doing the greater part of the work, (nearly all of it.) This is the explanation of 87 the common occurrence of pneumonia in these portions ; also of the compensatory breathing in the upper lobes in such con- dition, indicated by deeper and more hurried movement. The physiological experimentation of removing the chest muscles fully eontirms it. Respiration moves on as usual. As the lungs fill up, the muscular substance on the chest walls LIFT THEM OUT OF THE AVAY, so as not to interfere with LUNG EXPANSION. To do this requires considerable work, as in addition to their own weight they have to lift that of the upper extremities, being fully as much as they are able to do. If relieved of the weight of the upper extremities, by resting them upon a table, that amount could be expended in active effort to form a vacuum, and thus expedite the filling of the upper portions of the lungs. This is the explanation of the behavior of the asthmatic He rushes to an open window, and PROPS HIMSELF UPON HIS ELBOWS, thus keying up the muscles of the chest bv acting upon the scapulae through the ossa humeri. MUSCULAR MOVEMENT IN THE NECK TO FACILITATE VENOUS FLOW FROM THE INTRA-CRANIAL TERRITORY. When the circumstance has full appreciation that it is of the utmost importance to expedite escape of venous blood from the cranial excavation, where its detention hut for the short space of a minute, or even less time, would lead to fatal con- sequences, (by reason of the unyielding bony walls inhibiting arterial influx, else from rupture in its system of over-distend- ed capillaries or arterioles,) the study of the mechanism assumes commanding interest and importance. And the manner of arrangement of this system of blood tubing to effect the object sought, does not flag in degree of interest it excites as the student proceeds in the various steps of the inquiry; nor suffer by comparison with the wonderful and comprehensive vascular apparatus for the transportation of arterial blood through this matchless domain, the prime ob- ject being to dismiss venous blood out of the reservoirs for its collection, chiefly at the base of the brain, as rapidly as it col- lects in the sinuses, that deoxydized arterial blood may flow into them through this same system of vessels, the arterial ca- pillaries terminating in that of the venous. If the latter have arrest, the former become engorged, and life imperiled with 88 most alarming rapidity. And if eve1’ it begin again after such final arrest, it will be on condition only of previous vacation of the'venous blood, with tresb irrigation of brain suhshmce by arterial overflow, when respiration revives, followed more or less rapidly by cerebration, when all the splendid mechan- ism is once more in running order. And its movements may have arrest at any time in the same manner —it is a law of the vital mechanism. But resuscitation after such event is of most difficult performance. The nausea which precedes returning consciousne-s is Nature’s effort to overflow the brain substance with fresh arterial blood, by firm compression of the aorta trunk at the crural flood gate, effected through energetic ac- tion of the diaphragm. The increasing number of deaths from cerebral hemorrhage, and inflammation products which the smaller capillary hem- orrhage provokes in the brain substance, in public men, (speak- ers and musicians especially,) is undoubtedly due to venous obstruction in the respiratory apparatus, with the inevitable reflux upon the cerebral circulation it occasions. Venous flow from the lateral sinuses is specially aided by the wide permanent lumen of the deep jugular origin, and MODE OF TRANSIT BEHIND the great muscular ropes of the sterno-cleido-mastoid muscles, which give them safe con- duct to the great trunks of the venae in nominate, and slight remove only from the central reservoir. The relation which these venous conduits sustain to the muscular rones which di- vide the lateral aspect of the neck into their two great trian- gles, is strikingly illustrated in threatened asphyxiation. In this condition these muscles stand out as great cables stretched between the base of the skull and the middle of the auricles, not to dilate the latter, for their insertion would not pro- mote this movement, but on the contrary to perform a high order of work of a different character; being no other than to lift up atmospheric pressure from the jugular conduits and al- low for more rapid descent of the blood from the intra-cranial region. And the force of this pressure may have appreciation by the degree of crushing in of the softer cervical tissues, tight- ly fitting them around the muscular ropes, and by the great depth of the excavations at the root of the neck, resting upon the very apex of the lung. These uglv depressions are OUT- SIDE THE CLAVICULAR INSERTION of the cables. The double insertion below is the best possible arrangement for the distribution of this force so as to ward ofi‘pressure from 89 the great underlying canals near their confluence in the vena innominata of either side ; whilst their attachment to the mas- toid eminence on either side, by placing the broadest portion of the base of the skull between their upper extremities, is suf- ficient reason why these two great cords should stand out in relief their entire length and widen the neck in front when they tighten under the electric current. The arrangement to drain the venous reservoirs at the base of the brain would ap- pear to be perfect. Forced expiration, as in blowing upon wind instruments, or in carrying high notes, is obstructive to venous descent, as it is arrest of aspiratory force in the auri- cles, with consequent suspension of the onward movement in the venous column into the pulmonic territory. In this con- dition of lung collapse from constringing force, the stern o- cleido-mastoid muscles act with great energy in the effort to lift up atmospheric pressure from the two discharging conduits of the venous reservoirs of the encephalon. If these muscles were really inspiratory, as had been suspected, they are moving out of time when they become rigid in expiration. Moreover, they could not be inspiratory if they would, since they have insertion into the rigid and unyielding portions of the chest walls. They have triple functions, however, viz.; 1st. They move the head from right to left, and vice versa, by alternat- ing contractions, turning it upon its pivot. When they act together, (the trapezii not opposing,) they flex the head upon the breast 2d. They regulate venous flow through the deep jugulars. 3d. They aid in supporting the arm and shoulder. Deficient aeration of the blood is urgent necessity for hur- rying the circulation, Nature endeavoring to present as many red corpuscles for oxygenation as possible in a given time in the lung organs; hence the action of these neck muscles, to expedite venous descent as well as to relieve the brain. PHYSIOLOGICAL EXPERIMENTATION OF REMOVING THE MUSCULAR ENVELOPE OF THE CHEST WITHOUT EMBARRASSING RESPIRA- TION. Case 1. A large male cat was chloroformizecl, and the scap- ulae separated from the spinous attachments and clavicular ar- ticulation, and pushed in front, so as to relax and render inop- erative all the great muscular bundles of the chest surface. There was no interference with respiration. The small dorsal muscles having insertion into the angle of the ribs were next 90 divided, with similar result. The intercostals are so delicate in a cat, that for fear of penetrating the pleura they were let alone. The number of respirations before the operation was forty; after the operation they were also forty per minute. Respiration was not affected. The animal was now killed with chloroform, with the view of ascertaining the action of the drug upon the heart. When respiration had ceased altogether, the sternum was lifted up by separation from the cartilages, and the heart exposed. It was beating regularly in perfect rhythm- ic movement, and continued to do so for six minutes, growing more feeble after the first several minutes. Movement was most prolonged in the auricles. Case 2. A bull terrier was chloroformized and treated in the same manner with the cat. Respiration was not affected, con- tinuing a regular and gentle to-and-fro movement between the two great cavities. This dog was now trephined, to make ex- periment upon the brain circulation. Both hemispheres were uncovered. With each inspiration there was brain motion, and when sections were removed by the knife there was pro- fuse flowing of blood, hut no spurt or jet shot out of the arte- ries as in other portions of the body when an artery is divided. The brain is irrigated by gentle overflow. SELECTIONS FROM PHYSIOLOGICAL EXPERIMENTATIONS SHOWING COMPRESSION OF AORTA TRUNK AT THE CRURA OF THE DIA- PHRAGM, DURING CONTRACTION OF THIS MUSCLE IN INSPIRA- TION, WITH CORRESPONDING ARREST OF THE ARTERIAL FLOW THROUGH THE TUBE. Case 1. A strong male cat was chloroformized, and incision made on the left side from the inferior rib to the crest of the ilium, following the anterior margin of the quadratus lumbo rum muscle. The incision was several inches in extent, and made upon a grooved director till the peritoneum was reached, when it was laid aside; the index finger was then inserted and the peritoneum carefully pushed off the crura. This having been accomplished, the grooved director was cautiously inserted be- tween the right crus and aorta trunk, so as to isolate the for- mer ; and for better protection to the artery its groove was di- rected upward, and section of crus performed by cutting from the groove outward and upward, the hack of the bistoury rest- 91 mg in the sulcus of the instrument. I subsequently found the crus could be torn loose from its attachment to the lumbar vertebra. When it can be done without expenditure of great force, it is the preferable method, since the nutrient artery which supplies it causes some hemorrhage when first divided, though it always ceases of itself. After section, chloroform was discontinued. After more than ordinary delay, there were some symptoms of returning animation, but the pupils remain- ed large, with great amount of torpor. It was presently ob- servable that the animal was blind, and behaved m a singular manner, seeming to lack sense or intelligence It was placed in an open barrel and carefully watched. There was constant tremulous motion of the head, simulating paralysis agitans very remarkably. Whilst this was going on the animal seemed to be making effort to inspect its surroundings, moving its nose over the bottom of the barrel from side to side, as if in search of something, but not attempting to rise up, acting like an im- mature kitten freshly come into the world. There was com- plete anaesthesia, as no amount of tail bending or pinching at- tracted the least attention. When passing its nose over pieces of meat (which were now placed in front of it) it would stop for a moment, then resume its movements; after a time it made efforts to eat it, trembling violently all the while. The lower portions of the body were perfectly still. In an hour it could see some, but was not able to sit or stand up. It took some milk from a saucer. In an hour and thirty minutes it sat up, and began to pay some attention to its wound, but continued stupid to a degree. The tremulousness grew less, disappearing in two hours. Three hours subsequently it was sitting up, but dull and listless. It was placed in a large room and carefully attended. Intelligence improved with the returning activities. In four days the animal was killed intentionally with chloro- form. The heart continued its pulsations five and a half min- utes after the chest had been fully opened. Post mortem:— There was great contraction of aorta trunk below the superior mesenteric artery, extending beyond the renal artery. This portion was not more than half its natural size, round, hard, and of pipe-stem appearance; whereas the upper and lower portions of the tube were as large again and flattened out. This was the manner then that cerebral hydraulics had com- pensation made for the loss of haemic control higher up the tube. And as a result of this procedure, there was anaemia of the pelvic viscera, with diminution of the renal activity, at- 92 tested by greatly diminished excretion, and a bleaching of the lower viscera at the post mortem, as also of the kidneys As the animal kept very quiet, moving about but little, there was not great necessity for large amount of blood in the lower ex- tremities. Moreover, during such exercise the blood has most forcible direction upon the brain and spinal cord, where it is needed to generate muscular force, accumulating here and in the trunk, especially in the chest cavity. To exclude the factor of shock, which would probably have introduction to vitiate the force of the physiological bearing of the operation, another cat of equal size was chloroformized, and same extent of incision made at the same locality, (except- ing division of the crus.) Cold water was poured into the wound to intensity shock; in nine minutes the wounded cat got up and moved away. Case 2. A young dog, nearly grown and very active, being chosen on this account, was chloroformized and the crus di- vided as in the cat. When the grooved director had been in- serted it compressed the aorta so tightly as to arrest the arterial current, and in consequence suddenly aroused the cerebral ac- tivities, by the great arterial flow it determined over the brain substance, the animal making vigorous efforts to get away, and barking vociferously. At last, by dexterous movement, the knife was placed in the desii ed position and the crus divided. Immediately this was done all demonstration ceased, all move- ment stopped abruptly, and there was substituted a new and completely opposite order of vital phenomena for those that had arrested previous attention, viz: collapse, stupor and an- aesthesia. In an hour and a half the animal stood up, trem- bling with excessive weakness. It is remarkable, but a dog will make extraordinary effort to get upon his feet, and will stand as long as he possibly can. After three hours he showed some restlessness, moving about, but exhibiting great weak- ness, staggering, his hinder parts rocking from side to side. He was listless and torpid, though there was appreciable re- turn of intelligence as the interval since the operation increas- ed. He would stand as long as he could, then sit down, then lay down. The rocking of the hinder parts always taking place before the sitting down; he had to sit down from sheer debility, and assume a horizontal position from the same cause. After resting awhile he would get up and move about as be- fore, till the same symptoms recurred. He had lost control of his arterial circulation by reason of the ruined flood-gate, with ys consequent brain anaemia which it occasioned. 13ut in nine hours after this event he could move into a fast walk, and could even trot, urged by a rope around his neck, the party running in front. lie showed no sign of suffering from any- thing but languor and weakness, explained by the cerebral anaemia. The next day he was more improved, exhibiting considerable amount of intelligence, which was conclusive proof of arterial condensation somewhere in the great aorta trunk, compensating for the section of the crus. He relished his food, and moved about with freedom and evident pleasure. At the time of the operation, in order to eliminate the cir- cumstance of shock (which the profession believe in with such immeasurable faith, mistaking it as an entity, or something inherent in nervous action, when it is an alteration in the -hse- mic hydraulics only, involving diminished supply of arterial blood to the great cerebro spinal axis,) another dog was placed under chloroform and the parts divided to the same extent, excepting the crus. The dog was quite fat, and some of the viscera escaped through the rotten peritoneum, which had been injured by fatty metamorphosis. They were carefully replaced and the parts closed with inter- rupted suture. In fifteen minutes the animal sprang off the box he was lying on, which had served the purpose of opera- ting table, and had to be caught by the rope around his neck, and fastened, to prevent his- running away. The effects of chloroform quickly pass off. Respiration is not affected by division of the crus; more- over, that circumstance would not explain the symptoms. Nothing had happened the first dog differing from the other, save section of the tendon, with sudden loss of support to the cerebral blood column it occasions. Forty-eight hours after operation the wound in his side was still the skin flaps that had been twisted together with wire suture were loose and nearly free of secretion, there being no such exudation of plastic lymph, as occurs in the normal condition, to connect the lips of the wound and repair the injury, else by the granulating process The inference drawn from this latter circumstance was great arterial condensation of aorta trunk in the vicinity, cutting off or greatly reducing the blood supply to the lumbar arteries given off' from it, on the supposition arterial condensation had taken place at the point of election in the cat. Would his misfortune stop here? He had made great com- pensation for loss of arterial support at the ruined flood-gate ; 94 but what was it to cost him ? The activities originating in the cephalic mass could be abated in degree and frequency; but what of those residing in the sympathetic system below the point of constriction ? How compensate for deficient renal secretion ; for anaemia of the pelvic viscera; for anaemia of the lower extremities? Atrophy of his testicles, from deficient supply through the spermatic arteries, would hurt his powers of procreation only. I have him under observation. Case 3. A strong cur was chluroformized, and section of the right crus performed. Whilst the grooved director was in place he struggled to get up ; but when division was effected he lapsed at once into deep coma, so that no amount of pinching or tail bending had the slightest effect upon him. There was great dilatation of the pupils. He paid not the slight- est attention to the closing of his wound by sutures. In eighty minutes he succeeded in getting upon his feet, rocking a great deal in the hinder parts. He remained drunk till night, when no more observations were made. In the morning he was quite intelligent. In seven days the wound had not closed, nor the nutrive processes much advanced. The animal was killed and the wounded parts carefully inspected. There was great contraction of aorta trunk, extending above and below the passage of the crura, the condensation being uniform and continuous for nearly tw7o inches in extent. I have preserved a number of these arterial specimens, which sustain striking resemblance, the point of election, however, not always being the same portion of the tube, sometimes ex- tending higher up the thoracic aorta, in others reaching lower down the abdominal trunk. PHYSIOLOGICAL EXPERIMENTATIONS SHOWING THE CARDIAC FUNC- TION OF THE ABDOMINAL WALLS TO ASPIRATE AND TO EXPEL BLOOD OUT OF ITS VASCULAR APPARATUS, AND THE ESSENTIAL NATURE OF THIS FUNCTION TO THE CONTINUANCE OF LIFE. Venous blood is lifted from the lower portions of the trunk into the pulmonic reservoirs for oxygenation, through the agency of two great levers viz: MUS’ULAR FORCE in formation of vacuum areas, and co-operation of ATMOS- PHERIC PRESSURE FORCE. The veins contribute some- thing to the first of these two factors, but the major portion of 95 the work is performed by the great muscular envelope of the trunk, more especially through the walk of the ventricle. The following vivisections were made with the object of discover- ing the relative amount of labor performed on the venous cir- culation by the respective portions of the trunk; i. e. whether by the auricles or the great ventricle. Case 1. A full-grown female cat was chloroformized, and the phrenic nerve of each side divided, in order to paralyze the diaphragm, the arch of the ventricle and most active por- tion of its walls. There was great embarrassment to re spira- tion upon section of one of these nerves, hut after division of the remaining one death took place almost immediately. Post mortem examination : Much venous discoloration of abdomi- nal contents from great engorgement of the portal system, which was universal. The vena cava trunk and tributaries full of blood. Lungs normal; right heart full; lett one emp- ty. The descending cava and its depurating veins full of blood. The interpretation of tlie-e phenomena is simple enough. The big end of the ventricle having been paralyzed through section of the phrenics, the power to expel blood out of its vascular apparatus was no longer present; hence its ac- cumulation m such great quantity in so short a space of time. The absence of lung engorgement was due to the arrest of so much blood in the ventricle below, together with inability of the right heart to transfer the blood accumulating in its reser- voirs from the upper portions of the trunk into the pulmonic capillary system, which in consequence remained empty, the auricles not being able to form a vacuum without assistance from the diaphragm. And death was due to basilar anaemia from A OX-ARRI- VAL OF FRESHLY OXYGENATED RED CORPUS- CLES in the great nervous centres, the integrity of the phren- ic nerves being essential to the cardiac force in the ventricle, and the aspiratory force in the auricles, for the due circulation and oxygenation of the venous blood. Hence they are the most important nerve lines to the muscular envelope of the respiratory mechanism. Section of the pneumogastrics inter- feres with aspiratory force in the auricles by causing extensive paresis in its vascular apparatus and air tubing, with conse- quent delay in the onward movement of the blood, and expul- sion of air; these nerves being the motor and sensory tranks to its non-striated muscular substance and mucous membrane. And if it were not for the additional aid contributed through 96 the posterior pulmonic plexus from the upper dorsal medulla, life could not continue long after their section; as it is, much cough and dyspnoea follows it, with supervention of pneumonic inflammation, the animal finally dying of combined starvation with deficient aeration of the blood; not being able to swallow from the oesophagean paresis it occasions. Beyond a reasonable doubt, asthma is result of a neurosis of the pneumogastrics; in extreme cases probably involving the dorsal plexus of the lungs. Case 2. A dog, twenty-two pounds weight, (an English ter- rier,) was cliloroformized, and a grooved director inserted un- der the integument at the front edge of the quadratus lumbo- rnm of one side, carefully divided upon a line with the umbili- cus to a corresponding point upon the opposite side. The flaps were then carefully dissected up from the muscular substratum, so as to fully expose all this portion of the muscular envelope, the object being to leave no muscular power in the anterior portion of the ventricle. This was now carefully divided and liberated from the peritoneum by incisions crossing the fibres of the obliques and transversalis of either side. The rectus abdominis of either side was treated in the same manner, till finally muscular power in the anterior half of the great ven- tricle was abolished. The skin flaps were now replaced and secured bv running suture. The amount of blood lost was ex- ceedingly small; I do not think it exceeded one-half ounce. In the course of some fifteen or twenty minutes, when the chloroform narcosis had passed off, the animal made unsuc- cessful efforts to get up and move away; but when it did suc- ceed at last, staggered from side to side till it fell over upon the ground. To prevent this it would spread its legs and prop itself, changing the position frequently. It acted as though under cerebral concussion ; finally, it made a lunge for a pile of plank standing near, stacked upon pieces of wood, creeping nervously under it, its hinder parts rocking from side to side. It made the feeblest bark, and repeated it several times. It could not well have been lower, to have been heard twenty feet away. The animal did not appear to suffer, as it uttered no sound of distress, nor made attempt to examine its wound. Medicine would say the animal was under shock, as if there is such thing, irrespective of sudden withdrawal of blood supply to the cerebral cortex. In this instance it was attribu- table to non-arrival of the due amount of cerebral blood, for the generation of the cerebral processes, concerned in muscular 97 action and cerebration, or generation of thought. And charge- able to the loss of compression force over the cava ascendens and vena porta system of vessels. The animal lived twenty-three hours, dying of cerebral anae- mia. It warded off the fatal issue as long as possible, bv STANDING in a corner of its kennel, WITH ITS HEAD ALMOST TOUCHING THE GROUND, till within several hours of its death; this position being most favorable for keep- ing the cerebral circulation full. It made no complaint, the cere- bral anaemia being sufficient to repress the generation of pain, its entire time being occupied upon the haemic hydraulics, and life,s sustentation it involves. Post mortem two hours after death : No rigor mortis. In- tense congestion of abdominal viscera, with great fulness of vena cava ascendens and tributaries. Considerable lymph and peritoneal juice : congestion of inguinal regions and fulness of crural veins immediately adjacent; kidneys and spleen con- gested, and the liver of mahogany color; its venous stasis being so great. The gall bladder distended from loss of com- pression force. The pelvic viscera much discolored from venous stasis. Some fluid in the urinary bladder. The parie- tal peritoneum appear to be normal; viscera of chest cavity normal; the right heart full, the left one empty. There is a blanched appearance of the sub-cutaneous chest surface, of neck surface, of face surface, of peri-cranial surface, and of the cerebral surface and substance. Death was due to basilar anaemia, from excessive blood diversion to the vascular appa- ratus of the abdomen. In other more explicit statement, death was result of the non-expulsion of the blood out of the great ventricle in the heart of animal life, with the failure of the cerebral circulation which it involves. The result of the post mortem placed beyond question the mode of death, fixi ng it in the alterations effected upon haemic hydraulics in the abdomi- nal vascular apparatus, due to destruction of aspiratory and constringing force in its muscular walls, with resulting absence of power to lift the venous column into the pulmonary appa- ratus on its way to the left central reservoir for brain supply and general distribution. It therefore continued to accumu- late in the lower trunk, at the expense of the upper portions, till this great section became nearly exsanguine, and a longer continuance of life impossible, from extreme cerebral anaemia. Case 3. A large female cat was chloroformized, and the ab- dominal walls divided by crucial incision, extending from the <)8 ensiform cartilage to the pubes, and from one quadratus to the other, upon a line with the umbilicus, care being taken not to penetrate the peritoneum, by cautious insertion of the grooved director under the muscular bundles before division. The edges of the skin fiaps were then carefully readjusted, and se- curely fastened by running suture. A cord was passed through the deep tissues over the sternum and those over the pubis, and the ends pulled through so as to draw upon the upper and low- er fastening, and when the front of the great ring (which had suffered elevation and removal) had been pulled down to its proper position, the free ends were securely tied in the middle and the patient laid carefully away. She died in the night, and was cold and stiff in the morning, living perhaps for twelve to fifteen hours after the operation. Post mortem examination : Extreme engorgement of the entire viscera of the abdomen ; the cava trunk and portal sys- tem full of blood; liver of mahogany color ; gall bladder full; much injection of the stomach and intestines; spleen engorg- ed ; kidneys not so much congested; urinary bladder empty; some congestion at root of left lung; right heart partially fill- ed ; left one empty ; a blanched and exsanguine condition of the upper portions of the trunk; the skin surface and fasciae of the chest, neck and pericranium white and colorless; brain substance very white, and but little blood in the sinuses. Cause of death—BRAIN AN/K.MI A from blood diversion to the lower portions of the trunk; such diversion having been due to loss of muscular force in the great ventricle to lift it up the cava into the central reservoir for aeration and general distribution. Case 4. A female cat, two years old, was chloroformized, and the spinal medulla below the fifth dorsal vertebra destroy- ed by cutting through the arches of several dorsal lamellae, and running a wire from above downward, so as to destroy the cord. Recovery from chloroform speedy; complete paralysis in lower trunk. Three hours after the injury the animal stood upon its fore feet and regarded me when I went to inspect her. The hinder parts were stretched out upon the ground. The eye had a wild look, but she did not seem to suffer. There was no crying of distress, and the wild look I attributed to commencing brain anaemia. It was a dry eye from want of the requisite amount of blood, and abeyance of secretory func- tion in consequence Respiration not embarrassed. Duration of life twentv-four hours. 99 Post mortem examination : There is no red staining of the anterior peritoneal surface, as in the third case ; but the con- gestion of the abdominal viscera, from portal and vena cava obstruction, exceeds anything I have ever witnessed. All the viscera vm* intensely congested; the liver has a dark ma- hogany appearance, and the terminal trunks that converge into the portal veins seem twice their natural size. The kid- ney congestion is extreme; the gall bladder full to bursting; the urinary bladder empty; the crural, iliac, and common cava trunk full of blood ; some staining of the inguinal regions. In the chest cavity there is some pulmonary congestion, ex- plained by injury of the pulmonary dorsal plexus of nerves given off at the fifth dorsal vertebra. The heart moderately full of blood on the right side ; empty on the left; blanching of the tissues of the chest surface, of the neck surface, and of the face surface. Upon opening of the cranium no blood es- caped, so great had beeu the brain anaemia. Its surface is firm and blanched; no blood in basilar plexus. Death by basilar anaemia, from blood diversion below the diaghragm, chiefly in the abdominal cavity. The result of this experiment afforded incontrovertible proof that the abdominal walls have cardiac power to propel blood, and serve the purpose of a ventricle to lift venous blood into the chest cavity, otherwise it would not accumulate in the ex- cavation after paresis. The operation had this effect upon its muscular walls, and no force being present to drive out the blood it continued to accumulate, till sufficient deple- tion had taken place in the brain to suspend respiration. At- mospheric pressure force had been of great effect, but not suf- ficient to prevent accumulation, from loss of ventricular force. In order to eliminate the tactor of vascular paresis being the cause of the blood diversion, I resolved upon another opera- tion, which would remove that factor, giving the net result of paralysis of muscular energy only in the walls. I resolved up- on incision through the walls, so as to render conti action abor- tive in the systole, by emptying out the viscera, which takes off pressure from the portal system and cava trunk. Case 5. A large strong male cat, several years old, wras chloroformized, and incision made through the front walls of the ventricle from near the ensiform cartilage to the pubes. The contained viscera w’ere encouraged to present through the opening, but owing to the shortness of the suspensory liga- ments met with only partial success, ft was impossible in this 100 manner to completely empty the ventricle and prevent all pres- sure upon the vena porta and cava. Nevertheless, the animal remained in a stupor the whole time the viscera protruded, the cerebral circulation being insufficient for the generation of the mental processes. When the animal was pinched or disturbed it would make momentary effort to defend itself against the attack; but immediately its head would again fall to the earth and its eyes close in deep sleep. An hour was so occupied, when the viscera were replaced into the ventricle and the open- ing closed by interrupted suture. Five minutes afterward the animal revived, sat up, licked its paws, and examined its wound. After the expiration of some minutes, when anima- tion was complete, the interrupted sutures were quickly div'ded and the viscera again allowed to protrude. Torpor and mild coma ensued at once. Case 6. A large dog, of mixed breed, was chloroformized, and incision made through the linea alba, several inches in ex- tent. At inspiration some of the omentum protruded, the largest quantity escaping during the deepest inspirations. This was undoubted proof of a diminished abdominal area during inspiration; and reduction of area is in proportion to the energy of the inspiratory movement, being greatest at the height of deepest inspiration. This circumstance has many corrobora- tive facts in medical experience ; as hernial protrusions leaping outward during coughing and vomiting, or straining at stool. The incision was now enlarged to allow of the introduction of the hand, to make further exploration of the alterations that ensue in the abdominal walls during inspiration. The- dia- phragm initiates the movement, but after it has descended a little way from its high elevation, there is a counter movement in the lateral walls of the abdomen, growing in energy rapidly in the later stages of diaphragmatic descent. The lateral walls and diaphragm are in accord beyond a doubt, acting synchro- nously, and in this manner bring about reduction in the ab- dominal area, and cause visceral escape during inspiration. An incision was now made transversely through the walls from one quadratus to the other, upon a line with the umbilicus. The diaphragm immediately commenced contracting with the greatest energy, to compensate for the loss of muscular force below, felt at once upon the great nervous centres. The en- ergy of the diaphragm was very striking. The animal survived over an hour, when respiration had suspension from basilar anaemia. The central organ was now exposed, and found to be 101 pulsating as usual. After nine and a half minutes some mo- tson was still perceptible in the auricles, having but just disap- peared from the ventricles. Such frequent reference has been made to the PERSIST- ENCE OF CARDIAC MOVEMENT in all forms of death, that no occasion exists for further reference to it here, except perhaps to indicate the most effective mode of suspending its action, which is done by suffocating the animal, and is purely MECHANICAL in its mode of operation, the organ suffering such extreme degree of distention from amount of blood it con- tains as absolutely to inhibit systolic action. The right cavi- ties are full almost to bursting, as are also the jugulars and cerebral reservoirs. This mode of arrest of the vital me- chanisms is consequently the most difficult to recover from, or to effect resuscitation movement in; and we are of opinion that it would be good practice to relieve the distention of the right heart, by means of a trocar and canula inserted into the ventricle, the point of election being between the third and fourth costal cartilages on the right side, keeping close to the sternum, the point of the instrument having direction toward the mesial line. Blood drawn off in this manner would re- lieve not onlv the enormously distended organ, but also have most benign effect upon the vascular apparatus of the respira- tory centre. The heart is very tolerant of such manipulation, a circumstance I have most fully proven by repeated experi- ment. I have had an animal to revive with an awl transfixing the ventricles, after respiratory movement had ceased for some minutes, from the toxic effects of chloroform. It was revived by suspending it by the hind legs and making rhythmical com- pression around the chest wall (the left chest was open.) It made vigorous effort to get away, when I destroyed it instantly by cutting the ascending aorta from the heart. I have over and over again (after suspension of respiration by chloroform) exposed the heart from the left side, and made a puncture through the right ventricle, (the uppermost one,) the blood escaping through the wound into the pericardial sac, (in one instance almost filling it,) and have witnessed its ar- rest by formation of a clot occluding the cardiac wound, and had the animal to revive after suspension, and rhythmic com- pression of the right chest. We therefore have no hesitation in uttering the opinion that the heart is very tolerant of injury. A broad blade may sever important ganglionic connexions in its substance, hence should not he used; a trocar would not do 102 this. The explanatiun of cases of death following small cardiac wounds is not from primary suspension of cardiac movement, but to be ascribed to DIMINISHED energy in the organ, withholding the normal amount from the encephalic territory. And if the chest be opened, the organ would be found to con- tinue its movements for minutes later. It is the case when destroyed by a blow from an axe upon the head, or after being shot through the head, or after amputation of the head itself. It is the same after death from toxic agents. The persistence of cardiac movement over all other vital phenomena is a law of the animal mechanism. In case of sudden death from a stab wound, the body should have inversion, and rhythmical compression made around the chest. In respect of the difference of the cerebral circulation from other portions of the body, ascribed to unique modifica- tions in its vascular apparatus, the experiment of dividing an arterial trunk in one of the extremities,at the same time slicing off the brain substance till the terminal trunks of the internal carotids be opened, (having previously exposed it with the trephine,) will leave not longer room for doubt; for the instant the former artery suffers partial di- vision, a jet of blood shoots out of the wound to the distance of some feet beyond the body; whereas, when made into the internal carotids, blood rushes over the contents till it over- flows the cavity, and runs down the outside walls, hut never jets or spurts out upon the floor, as in the former case. Muscular energy is the force of the circulation, and since the MEDULLA ' BULB IS THE CENTRE OF MUSCU- LAR FORCE, it follows as a corollary it is the centre of AR- TERIAL FORCE; and such really is the case, for if the pos- terior lobes of the great hemispheres be carefully removed, and the index finger be gently pressed upon the cut surface of the pons so as only to stimulate the nerve substance, the heart will be hurried into tumultuous action. The finger maybe passed down to this region without removal of much brain substance. The chest should be laid open so as to expose the heart and have it under observation during experiment. The par vagum like other spinal nerves is motor and sensory, a small spinal cord, administering to the vascular apparatus of the chest and abdominal viscera, and distributed to its NOX-STRIATED muscular substance and MUCOUS MEMBRANE. After section of these nerves there is paralysis of oesophagus, stom- ach, and upper portion of intestinal tube; as also over consid- 103 erable portions of the pulmonary apparatus, making respirato- ry movement difficult, from inability to express the blood and air; and but for the pulmonic plexus of nerves given off at the fourth and fifth dorsal vertebrae, the animal would die speedily from asphyxia. Loss of nervous force to the heart has degree of compensation made through the three pairs of cervical ganglia. The oesophagus receives some assistance from the pulmonic plexus, and spinal influence upon the viscera of the abdomen in- creases from this point down. The great solar plexus receives the three pairs of splanchnic nerves, as also some power through the phrenies. For this reason, section of the great pneumogas- tric wires is not followed by absolute paresis of the chest or- gans and upper abdominal viscera, yet is sufficient to occasion severe cough and pneumonia within a few hours, with progres- sive increase till the animal perish, or is killed out of feeling of commiseration. If life be not terminated by pneumonia it w
