DUNGLISON’S MEDICAL DICTIONARY. MEDICAL LEXICON; A DICTIONARY OF MEDICAL SCIENCE, CONTAINING A CONCISE EXPLANATION OF THE VARIOUS SUBJECTS AND TERMS OF PHYSIOLOGY, PATHOLOGY, HYGIENE, THERAPEUTICS, PHARMACOLOGY, OBSTETRICS, MEDICAL JURISPRUDENCE, Ac., Ac.

'■ BY ROBLEY DUNGLISON, M.D., Professor of Institutes of Medicine in the Jefferson Medical College, Philadelphia. TWELFTH EDITION, REVISED. In one very thick octavo volume, of over nine hundred large double-columned pages, strongly bound in leather, with raised bands. Notwithstanding the large size and completeness of this standard work, the price at which it is offered places it within the reach of all. We welcome it cordially; it is an admirable work, and indispensable to all literary medical men. The labor which has been bestowed upon it is something prodigious. The work, however, has now been done, and we are happy in the thought that no human being will have again to under- take the same gigantic task. Revised and corrected from time to time, Dr. Dunglison’s “ Medical Lexicon” will last for centuries.—British and Foreign Med. Chirurg. Review. The fact that this excellent and learned work has passed through eight editions, and that a ninth is rendered necessary by the demands of the public, affords a sufficient evidence of the general appreciation of Dr. Dunglison’s labors by the medical profession in England and America. It is a book which will be of great service to the student, in teaching him the meaning of all the technical terms used in medicine, and will be of.no less use to the practitioner who desires to keep himself on a level with the advance of medical science.—London Medical Times and Gazette. In taking leave of our author, we feel compelled to confess that his work bears evidence of almost incredible labor having been bestowed upon its composition.—Edinburgh Journal of Med. Sciences. A miracle of labor and industry in one who has written able and voluminous works on nearly every branch of medical science. There could be no more useful book to the student or practi- tioner,,in the present advancing age, than one in which would be found, in addition to the ordinary meaning and derivation of medical terms — so many of which are of modern introduction concise descriptions of their explanation and employment: and all this and much more is contained in the volume before us. It is, therefore, almost as indispensable to the other learned professions as to our own ; in fact, to all who may have occasion to ascertain the meaning of any word belonging to the many branches of medicine. From a careful examination of the present edition, we can vouch for its accuracy, and for its being brought quite up to the date of publication; the author states in his preface that he has added to it about four thousand terms, which are not to be found in the preceding one—Dublin Quarterly Journal of Medical Sciences. It is certainly more complete and comprehensive than any with which we are acquainted in the English language. Few, in fact, could be found better qualified than Dr. Dunglison for the pro- duction of such a work. Learned, industrious, persevering, and accurate, he brings to the task all the peculiar talents necessary for its successful performance; while, at the same time, his fa mi. liarity with the writings of the ancient and modern “masters of our art,” renders him skilful to note the exact usage of the several terms of science, and the various modifications which medical terminology has undergone with the change of theories or the progress of improvement.

TO MARSHALL HALL, M.D. F.R.S., &c., THIS LITTLE WORK, UNDERTAKEN AT HIS SUGGESTION, AND PROMOTED BY HIS ASSISTANCE, £s EnscttbeU fiij THE AUTHOR. EDITOR’S PREFACE. The object of this work is to present to the Student, in a concise form, an explanation of the terms most used in Medicine, and the Sci- ences connected with it, by giving their etymology and signification. This design the author has so ably executed as to have elicited the highest encomiums of the Medical Press. Believing that its republication in this country would be useful, the Editor consented to revise and adapt it to the wants of the American practitioner. With this view he has added, not only the terms re- cently introduced, but also the names of our native medicinal plants,— the formulae for the officinal preparations, &c.,— and has made the work conform with the latest edition of the Pharmacopoeia of the United States. For the greater convenience of reference, he has also inserted in the body of the work most of the interesting articles placed by the author in an Appendix; and also the Terms contained in the “Sup- plementary List” to the last London edition, with the exception of those under the first few letters of the alphabet, which have been appended in a separate list. To accommodate these additions, not only has the size of the page been materially enlarged, but also the number of pages has been increased by more than one hundred. The Editor has availed himself of very many recent sources of information in preparing his additions, among which he would especially mention the Expository Lexicon, by Dr. R. G. Mayne ; Medical Bo- tany, by the late Dr. R. E. Griffith ; the recent works of Carpenter, Raget, Owen, and Jones and Sieveking; and the admirable United Stales’ Dispensatory of Professors Wood and Baciie. The aim of the Editor has been to render the work more complete, not by incorporating in it obsolete words, but by adding such as modern investigations and doctrines have introduced, so that the student should be afforded an explanation of all the terms at present in use. The Editor’s additions are enclosed within brackets. Philadelphia, September, 1855. PREFACE TO THE SIXTH LONDON EDITION. The present edition of the Dictionary of Medical Terms has been enlarged by the addition of sixty pages, including the terms of the most recent introduction, and thus continuing the nomenclature em- ployed in Medicine and the collateral Sciences, to the present day. 2 Sussex Place, Regent’s Pakk, August 1, 1854.

Gomphosis (ySpupos, a nail). Nail-like insertion, as of the teeth in their sockets; their roots being fixed into the alveoli, like nails into a board. This is the only ex- ample of this kind of articulation. 4. Sutura. Literally, a seam. A dove- tailing mode of articulation, the most solid of the four forms of synarthrosis ; it occurs in the union of the flat bones of the skull with each other. There are two varieties, viz:— 1. Sutura serrata, as in the serrated, or saw-like union of the frontal with the parietal bones, and of the parietal bones with each other. 2. Sutura squamosa, as in the scale- like connexion of the temporal with the parietal bone. II. Diarthrosis, or Movable. 1. Arthrodia. In this form of articula- tion, the extent of motion is limited, as in the articulation of both extremities of the clavicle, and ribs; in the articulations of the radius with the ulna, of the fibula with the tibia, of the articular processes of the vertebrae, and of the bones of the carpus and tarsus with each other, Ac. 2. Ginglymus {yiyyXvpbs, ahinge).

Ball-and-socket joint, the most extensive in its range of motion of all the movable joints. There are three examples of this kind of joint, viz., the hip, the shoulder, and the articulation of the meta- carpal bone of the thumb with the trape- zium. III. Amphi-arthrosis, or Mixed. This kind of articulation is intermediate between the immovable and the movable forms. It is characterized by having an intervening substance between the conti- guous ends of the bones, and permitting only a slight or obscure degree of motion. Examples occur in the connexion between the bodies of the vertebras, the union of the two first pieces of the sternum, and the sacro-iliac and pubic symphyses. [ARTIFICIAL ANUS.

ATOM (a, priv.; Tipvm, to cut). An ul- timate particle of matter, incapable of fur- ther division. The term is frequently used in chemistry as synonymous with equiva- lent. ATOMIC THEORY. A theory intro- duced by Dalton for explaining the laws of definite preportions in chemical combi- nations. It is founded on the supposition that matter consists of ultimate indivisible particles, called atoms: that these are of the same size and shape in the same body, but differ in iveight in different bodies; and that bodies combine in definite proportions, with reference to those weights, which are hence called atomic weights. The main features of this theory are briefly stated in the following paragraphs :— 1. In bodies capable of assuming the gaseous form, the weight of the atom is obtained from the volume ; thus, water be- ing composed of one volume of oxygen, united with two volumes (or one atom) of hydrogen, the relative weights will be, oxy- gen 8, hydrogen 1, and water 9. 2. In bodies which do not assume the gaseous form in their simple state, the weight of the atom is deduced from that of the compound; the weight of carbon, for instance, is obtained from that of car- bonic acid gas, one volume of which weighs 22 times as much as our standard of unity; of these 22 parts, 16 are oxygen, leaving 6 to represent the primary molecule of carbon. ATO 58 ATR 3. In the case of bodies which are inca- 1 pable of assuming a gaseous form, either alone or in combination, the weight must be obtained by analysis; thus, marble, or the carbonate of lime, is found to be com- posed of 22 parts of carbonic acid, and 28 of lime; 28 therefore represents the ato- mic weight of lime. 4. The atomic weights are generally sup- posed to be related to one another by mul- tiple ; hence, this law is often called the law of multiples, or of combinations in multiple proportion. This will be easily seen by referring to the component parts of the following substances. Nitrogen. Oxygen. Nitrous oxide 14 8 Nitric oxide 14 16 Hyponitrous acid 14 24 Nitrous acid 14 32 Nitric acid 14 40 5. When only one combination of any two elementary bodies exists, Dr. Dalton assumes that its elements are united, atom to atom singly, by what he calls binary combinations; if several compounds can be obtained from the same elements, they combine, as he supposes, in proportions expressed by some simple multiple of the number of atoms; as in the following table:— Atoms 1 of A -f-1 of B = 1 of C, binary. 1 of A -j- 2 of B = 1 of D, ternary. 2 of A -f- 1 of B = 1 of E, ternary. 1 of A -j- 3 of B = 1 of F, quaternary. 3 of A -f- 1 of B = 1 of Gr, quaternary. Berzelius has proposed a different classi- fication of atoms; viz., into— 1. Elementary atoms; and 2. Compound atoms, which are— 1. Compound atoms of the first order, or atoms formed of only two ele- mentary substances united. 2. Organic atoms, or those composed of more than two elementary sub- stances ; these he has named from their being only found in organic bodies, or bodies obtained by the destruction of organic matter. 3. Compound atoms of the second order, or those formed by the union of two or more compound atoms, as the salts. 6. Dr. Wollaston applied the term equi- valents to the combining proportions of elementary and compound substances, as, for instanco, the quantities of acid and base, in salts, required to neutralize each other: thus, 100 parts of sulphuric acid, and 68 parts of muriatic acid, are equiva- lents of each other, being both necessary to saturate 71 parts of lime. 7. After all, Dr. Donovan observes that there is not, perhaps, a word in the lan- guage that conveniently expresses the quantity of a body which enters into com- bination. Atom is not only hypothetical, but often inapplicable, as when half atoms occur. Equivalent is only expressive when comparison with a correlative equivalent is directly implied. Proportion means si- militude of ratios. Proportional is one of the terms of a proportion. Combining quan- tity or iceight is sometimes expressive, but, besides being unwieldy, it is not always applicable. Dr. Donavan adds, the word dose is universally employed to designate a determinate or definite quantity of a thing given; it has the quality of involving no- thing beyond a fact, and can often be used with advantage. ATONIA (a, priv.; vivos, tone). Atony; a defect of muscular power. [ATRABILIARY (atrabilis, black bile). Appertaining to black bile.

The act of listening by the application of the ear, in the examination of disease. It is termed immediate, when practised by the unassisted ear; mediate, when performed by means of the stetho- scope. I. Sounds of the Respiration. 1. Vesicular Respiration is the sound of respiration produced in the vesicles of the lungs; it denotes that the lungs are per- meable to air. It is at its maximum in infants, and is termed puerile; at its mini- mum in the aged, and termed senile. 2. Bronchial Respiration is the sound of respiration, as heard in the larynx, tra- chea, and large bronchi; it appears dry, and the air seems to be passing through a large empty space. There are several va- rieties of this sound. 3. Cavernous Respiration is the sound of respiration produced in morbid cavities of the lungs. During expiration, the wind appears to be puffed into the ear of the auscultator. 4. Souffle, or Blowing, is a sound resem- bling that of the air being actually drawn from or propelled into the ear of the aus- cultator, when the patient speaks or coughs. The ‘souffle ’ is sometimes modified by the sensation, as of a veil interposed between a cavity and the ear, and is then termed souffle voiU, or the veiled blowing sound. II. Rattles, Rales, or Rhonchi. 1. Vesicular, or Crepitating Rattles, are of two kinds; the moist and the dry. The former resembles the noise of salt thrown on the fire; the latter, that made by distending a dry bladder. The moist sound runs into the varieties of the bron- chial rattle, and, when the bubbles are large, is called subcrepitation. 2. Bronchial Rattles are distinguished into the mucous, the sonorous, and the si- bilant. The first resembles the rattling in the throat of the dying; the second, a sort of snoring sound, the tone of a base string AUT 61 AUT in vibration, or a cooing sound; the third, a whistling sound. The mucous rattle, when seated in the bronchi or cavities, is termed cavernous, or gargling. III. Sounds of the Voice. 1. Bronchophony is the resonance of the voice over the bronchi. It traverses the tube of the stethoscope, and is very similar to pectoriloquism. In thin persons it re- sembles laryngophony. 2. Pectoriloquism is distinguished from bronchophony by its cavernous and cir- cumscribed character. The voice comes directly from the chest to the ear, as if it were formed within the lungs. It may be perfect or imperfect. 3. HUgophony is a sound resembling the bleating of a goat, or a snuffling human voice. It seems as if an echo of the voice, of an acute, harsh, and silvery character, were heard at the surface of the lungs, rarely entering, and scarcely ever travers- ing, the tube of the stethoscope. IV. Sounds of Cough. 1. Tubal Cough is a resonance of the concussion produced by coughing, over the larynx, trachea, and large bronchi. There is the obvious sensation of an internal canal. It denotes that the air is not al- lowed to enter the cells of the lungs. 2. Cavernous Cough is the resonance of the concussion produced by coughing, over a cavity. It is attended by cavernous rattle. 3. Metallic Tinkling resembles the sound of a metallic vessel, or glass, struck by a pin. It is heard in respiration, but espe- cially when the patient speaks or coughs; it is sometimes heard in cough, when in- audible in the respiration or in the voice. 4. Amphoric Resonance is a sound like that heard on blowing into a decanter. It is heard under the same circumstances as the previous sound. V. Sounds of the Heart. 1. Cri du cuir neuf. The sound resem- bling the creaking of the leather of a new saddle. This sound has been supposed to be produced by the friction of the heart against the pericardium, when one or both have lost their polish from the effusion of solid lymph with little or no serum. 2. Bruit de soufflet. A sound of the heart resembling the puffing of a small pair of bellows, as employed to blow the fire. This sound usually takes the place of the natural one; sometimes the two are conjoined ; it may take place during the first and second sound, or only during one of these. 3. Bruit de scie. A grating sound of the heart, resembling that produced by the action of a saw upon wood; and— 4. Bruit de rape. A grating sound of the heart, like that produced by the action of a file or rasp. There is every interme- diate gradation, from the smoothness of the bellows-sound to the roughest sounds produced by a large-toothed saw. 5. Frimissement cataire of Laennec, or bruissement of Corvisart. A peculiar thrill or tremor, perceived by the finger when applied to the heart or artery where it exists, resembling that communicated to the hand by the purring of a cat. VI. Sounds of the Arteries. 1. Bruit de souflet intermittent. An in- termittent blowing sound, occasioned by contraction of the calibre of an artery, from tumour, &c. It is sufficient to compress the artery with the stethoscope to produce this noise. 2. Bruit de soufflet continu. A continu- ous blowing and snoring sound, resembling the blowing noise of the bellows of a forge. The bruit de diable, or sound of the hum- ming-top, is a variety of this soufflet. Sometimes a kind of tune of the arteries is heard, resembling the humming of certain insects; this is called siffement moduli, ou chant des arteres. VII. Sounds of Pregnancy. 1. Bruit Placentaire. A sound of the placenta, produced, according to Bouillaud, by compression of one of the large vessels of the abdomen by the gravid uterus. It is analogous to the intermittent blowing sound of the arteries. 2. Double pulsation of the heart of the foetus. A tolerably exact idea of this noise will be obtained by listening to the tic-tac of a watch placed under a pillow upon which the head rests. It occurs at the middle of the period of gestation. [AUTOGENOUS (avros, itself; ycvofiai, to be born).

CLIMATE (ic\!pa, a region). This term denotes, in medicine, the condition of the atmosphere of different countries, or districts, in reference to their effects upon the health of persons inhabiting them. The following observations, com- piled from the well known work of Sir James Clark, comprises, 1, a brief account of the condition of the atmosphere of dif- ferent countries, or districts, in reference to their effects upon the health of persons inhabiting them; and, 2, an enumeration of those diseases which are most deci- CLI 109 CLI dedly benefitted by change of climate, and the particular situation most suitable to each. I. English Climates. The great desiderata in this country are a mild climate and sheltered residence for pulmonary and other affections, during the winter and spring. The districts of Eng- land may be divided into— 1. The South Coast. — This compre- hends the tract of coast between Hastings and Portland Island, including the Isle of Wight. The superiority of the climate of this district exists chiefly during the months of December, January, and Febru- ary. The principal places are— (1.) Undercliff, in the Isle of Wight, the most sheltered and warmest of all these places; it affords also a good sum- mer climate. (2.) Hastings, which follows next in point of shelter and warmth, during the winter and spring months. (3.) Brighton, which, though inferior to the preceding places as a residence in diseases of the respiratory organs accom- panied with much irritation, is of a drier and more bracing atmosphere. Autumn is the season during which the climate of this place possesses the greatest advan- tages. 2. The Southwest Coast.—This reaches from the Isle of Wight to Cornwall. The temperature of the more sheltered spots of the south coast of Devon, during the months of November, December, and Ja- nuary, is, on the average, about five de- grees higher than that of London during the same period ; whereas on the south coast, the difference scarcely exceeds two degrees. The principal places are Tor- quay, Dawlish, Sidmouth, and Exmouth: the first of these is the most sheltered place in the island; Salcombe, the Montpelier of Huxham, is one of the warmest spots in this country during the winter. 3. The Land’s End. — This district is most suitable for the irritable and inflam- matory habit, and least so for the relaxed nervous constitution. The only places in this district deserving particular notice, are — (1.) Penzance, which is remarkable for the equal distribution of its temperature throughout the year, throughout the day and night; indeed, it is only excelled in this respect by the climate of Madeira. The difference between the warmest and coldest months in London is 26°; at Pen- lance, it is only 18°. The climate of the Land’s End is, however, very humid, and, from its exposure to tho northerly and easterly winds, colder during the spring than Torquay or Undercliff. (2.) Flushing, a small village in the vicinity of Falmouth; its position differs from that of Penzance only in being somewhat protected from the north and east winds. 4. The West of England.—This com- prehends the places along the borders of the Bristol Channel and estuary of the Severn. Of these it is necessary only to notice — Clifton, which, compared with the South- west Coast, is more exciting, more bracing, and drier, but not so mild; it is therefore better suited to a relaxed, languid habit, and less so for pulmonary and other dis- eases, accompanied with irritation and a tendency to inflammation. II. Foreign Climates. 1. The Southwest of France. — This comprehends the tract of country extend- ing from Bourdeaux and Bayonne to Tou- louse. The mean annual temperature is only about four degrees higher than that of the southwest of England; both are soft and rather humid, and agree and dis- agree, generally speaking, with diseases of the same character. The only place in this district which need be here noticed, is — Pau, a little town remarkable for the mildness of the spring, and its comparative exemption from sharp cold winds during that season ; its chief fault is the unsteadi- ness of its temperature. 2. The Southeast of France.—This includes that extensive tract of country which stretches along the shores of the Mediterranean, from Montpelier to the banks of the Yar, the boundary stream between France and Piedmont. The climate of this district is warmer and drier, but more irritating and exciting than that of the Southwest. It is also subject to sudden vicissitudes of temperature, and to frequent harsh, cold winds, especially the mistral, or the northwest, rendering the whole of this country an improper resi- dence for patients suffering under, or pecu- liarly disposed to, inflammation or irri ta tion of the respiratory organs. The principal places are— (1.) Montpelier, the high and exposed situation of which renders it liable to all the above mentioned objections in a re- markable degree,1 it is well ascertained that pulmonary inflammation and phthisis are among the most prevailing diseases of the place. (2.) Marseilles, which, though less ex- posed than the preceding place, is an CLI 110 CLI equally improper residence for consump- tive invalids. It forms a good winter residence for persons likely to benefit by a dry sharp air. (3.) Hyires, which possesses the mildest •climate in the whole of this district, being sheltered to a considerable degree from the northerly winds. 3. Nice.— This plaee, situated in the same line of coast as Provence, is supe- rior to it in several respects : it is pro- tected from the northerly winds, espe- cially the mistral; but it is not exempt from cold winds, especially during the spring, and is therefore considered an unfavourable situation for consumption, even in its earlier stages, for bronchial diseases of the dry irritable character, and for dyspepsia depending on an irri- tated or inflammatory condition of the mucous membrane of the stomach. This climate is found useful for languid, torpid constitutions, for scrofulous affections in persons of this kind of constitution, for chronic bronchial disease, accompanied with copious expectoration, for humoral asthma, &c. The summer at Nice is too hot for any class of invalids. 4. Italy.—The climate of the south of Italy differs little in actual temperature from that of Provence and Nice, but it is softer, more humid, and less exciting. On the other hand, the sirocco, which is scarcely felt at the latter places, forms an objection to the Italian climate, though this objection is of not much weight during the winter. The diseases in which the climate in Italy proves most benefi- cial, are chronic bronchitis and rheuma- tism. The principal places for winter cli- mates are — (1.) Rome, which possesses one of the best climates in Italy: to the invalid, ca- pable of taking exercise in the open air, it affords advantages over both Naples and Pisa. It is somewhat warmer in the winter, and drier than Pisa, though more humid than Nice and the parching climate of Provence. (2.) Pisa, which resembles Rome in its general qualities, but possesses advan- tages over every other place in Italy, for patients who can bear little exposure to the air. (3.) Naples, which is more subject to winds, and the air of which is more ex- citing than that of Pisa or Rome. As a residence for invalids labouring under pul- monary irritation, or chronic rheumatism, it is inferior to both. 5. The Mediterranean Islands.— Some parts of the coast of Sicily afford a pretty good winter climate; it is, however, difficult to obtain in these parts the com- forts and conveniences of life. Although exception may be made in this respect in favour of Malta, the climate of this island has little to recommend it to any class of invalids, least of all to such as suffer from pulmonary affections. 6. Atlantic Climate.—The climate of the Northern Atlantic, in the temperate latitudes, is more steady than that of the Mediterranean, and imparts a similar cha- racter to the climate of its islands. The principal of these are — (1.) Madeira, the mean annual tempe- rature of which is only about six degrees higher than that of the southeast of France and Italy; this temperature is, however, very differently distributed throughout the year, the range being far less at Madeira than in the most favoured spots in the south of Europe. Thus, while the winter is twelve degrees warmer than in Italy and France, the summer is five degrees cooler; and, while the mean annual range at Madeira is only fourteen degrees, it is nearly double this at Pisa, Rome, Naples, and Nice. Madeira affords the best climate of the Atlantic Islands for consumptive cases ; Funchal is the most desirable for a winter residence. (2.) The Canary Islands, which rank next to Madeira in point of climate; they are somewhat warmer, but the excess of temperature is not equally distributed over the whole year; for while Santa Cruz, the capital of Teneriffe, is seven degrees warmer than Funchal in summer, it is only five degrees warmer in winter. The temperature is also more equable through- out the year at Madeira than at Teneriffe; the difference between the mean tempe- rature of summer and winter being 9° at the former place, while it is 12° at the latter. (3.) The Azores, or Western Islands — which in their external characters resem- ble Madeira and the Canaries. The cli- mate appears to be mild, but somewhat humid; less warm than Madeira during the winter, and more oppressive during summer. (4.) The Bermudas, which differ little from Madeira in the mildness of their winter climate; they are, however, much more liable to high winds in the winter, extremely hot during the summer, and quite improper at this season for the resi- dence of such invalids as are likely to be sent from this country. (5.) The Bahamas, in which the winter and spring are considerably cooler than the same seasons in the West Indies, while the temperature of the summer CLI 111 CLI and autumn is nearly the same. During the winter, the temperature is subject to rapid and considerable vicissitudes, and cold, harsh, northerly winds are not un- frequent. (6.) The West Indies — of which the mean annual temperature, near the level of the sea, is about 80°, and during the six months which include the winter season, the temperature is only 2° lower. The extreme annual range does not ex- ceed 20°, while the mean daily range throughout the year is only 6°. Hence, this climate is improper, generally speak- ing, for consumptive invalids, who, never- theless, are frequently sent there. Calcu- lous disorders and scrofula are extremely rare in the West Indies; gout is not com- mon ; and rheumatism neither frequent nor severe. [III. Climate of the United States. [The United States stretch over a vast extent of territory, and embrace a corre- sponding variety of climate. The late Dr. Forry, who investigated this subject with much care, classified the country in three general divisions, embracing three systems of climate, viz.: the Northern, the Middle, and the Southern. [1. The Northern Division This extends on the Atlantic coast from East- port, Me., to the harbour of New York, and is characterized by great range of temperature and violent contrasts in the seasons; the rigour of the climate being somewhat tempered on the sea-eoast by the ocean, and in the region of the lakes by those inland seas. [2. The Middle Division.— This ex- tends from the Delaware Bay to Savan- nah, and is characterized by great varia- bleness of temperature, though the ex- tremes are much less than in the Northern Division. [3. The Southern Division.—This em- braces the whole region south and west to Texas and the Rocky Mountains, and is characterized by the predominance of high temperature. 1. Pulmonary Consumption. Of the At- lantic Islands, Madeira; in Italy, Rome and Pisa; and in England, Torquay and Undercliff afford the best climate for con- sumptive eases. [The Peninsula of Florida is charac- terized, according to Dr. Forry, by mild- ness and uniformity of climate; and al- though the air is more humid than in the northern divisions, the atmosphere in winter is comparatively dry and se- rene, in consequence of much the larger proportion of rain, nearly two-thirds of the whole falling during the six months from May to November. The most fa- vourable situations for invalids labouring under bronchitis and incipient phthisis, Dr. Forry states to be Fort King, in the interior; Key Biscayno on the southeast- ern coast; and Tampa Bay on the Gulf of Mexico. St. Augustine, on the eastern coast, Dr. F. conceives to be less favour- able, in consequence of the frequency and severity of the northeast winds, which are chilly, and surcharged with vapour, and forbid the valetudinarian venturing from his domicile. Dr. Dunglison, how- ever, adduces some evidence leading to a more favourable estimate of the suitable- ness of St. Augustine as a winter residence for invalids; and at all events showing that it is a far more favourable locality for a winter retreat than the northern portions of the United States.] 2. Chronic Bronchitis. Of the conti- nental climates, those of Rome and Pisa are the most beneficial in cases attended with an irritable state of the affected parts without much secretion; and that of Nice, in cases attended with less sensibility, a more copious expectoration, and a relaxed state of the system generally. Madeira has been found more beneficial in the for- mer class than in the latter. In England, Torquay and UnderclifF afford the best climates in the first class of cases, and Clifton in the latter, in which Brighton also is a very favourable residence during the autumn. 3. Asthma. For humoral asthma, Nice is the best residence; but Rome is prefe- rable when this disease is accompanied with an irritated state of the digestive or- gans, a complication which is exceedingly common. 4. Chronic Rheumatism. Rome and Nice are the best residences for persons suffering from this complaint. When the patient’3 constitution and digestive organs are irri- table, the latter has been observed, gene- rally, to disagree, whatever may be the more prominent disease, s. 5. Gout. A warm climate is found to alleviate this disease. It is of rare occur- rence at Genoa, and has been remarkably relieved by residence in the West Indian climate. 6. Scrofula. Nice and Rome have been found to be favourable residences; and in some cases, the climate of the West Indies has proved more effectual than any in Europe, viz., those of an indolent character, with little disposition to febrile excitement. 7. Dyspepsia.
