SH E chief end of Oleography, as I take it, is to enable practitioners to cure the dif- eales to which the bones are liable, with more cafe, dexterity, and certainty, than otherwife they could be capable of. But how little Mr. C h £ s e l d e n has had this truly laudable defign in view, through the whole of this large andmoft expenfive work, will appear to the Incorrupti Ju dices from the following obfervations. In the title he calls his book, “ The Anatomy of the Bones " but whether of the bones of a Man, a Man-Tyger, a Bat, a Rat, or what elfe, he leaves the reader to guefs. It confifts of a Preface to the reader, an Introduftion and eight little Chapters : (above three parts of which had been publiflied four times before in 8vo.) They may be all read in Ids than two hours, yet the fublcription price was four guineas; and thofc which were not fubfcribed for, viz,, above three parts of the whole, as I have been informed, are not to be fold (as ooir author allures us) under fix guineas, and will coft a guinea binding, which is in all Seven Guineas for a book on the Bones. 2 Animadverfions on £)u~~ of a faint, for nature could not do it. “ Chapter II. u Of the bones of the face,” &c. Parag. I. “ Offa Nafi, make the upper part of the nolc; ** they form that kind of Arch which is fitteft to fuftain fuch “ injuries as the nofe is moft expofed to,” Pray what kind of an arch is that 1 A That fort of an arch which nature thought moft proper. Great news indeedi! Parag. 5. “ Maxilla Superior, is always deferibed Angle, •c tho’ it is manifeftly divided by a future, which is fegree f‘ ever obliterated.’* Mr. Chefelden’s Bones, See. 7 This aflcrtion would make any man believe, that Mr. Cheselden had never read any books on the bones, but his own ; for the firft three books I turn’d to, to examine the truth of it, viz. Heister, Drake, and Monro,all deferibc it as two bones. With what grace then, can he affert that its always defcribed Angle? and continue it through five different editions: nay, its fo far from being always defcribed Angle, as he afferts, that I don’t remember I ever met with one au- thor, ignorant enough to do fo. Qutre. Whether this fmells moft of H n labour, or lupine negligence ? Parag. 5. w Between the pofterior grinding teeth and the M orbits of the eyes are two great finus’s, called Antra “ Maxilhe Superioris, which open into the upper part of the u nofe. Part of the fides of thefe cavities, that lie next the 41 nofe, are only membranes which make the cavities like “ drums, perhaps to give a grave found to the voice when “ we let part of it through the nofe; but brutes not need- u ing fuch variety of founds, have thefe cavities open to the nofe, and filled with lamellae, which are covered “ with membranes, in which the olfactory nerves termi- ** nate, for a more extpuifite fenfe of fmelling than is nc- “ ceffary for men.” What a digreflion is here ! from a defeription of the An- tra of the jaw, to the founds of the voice in men, and the fenfe of fmelling in brutes ? What connexion, what ana- logy, what relation is there between thefe fubjeds and a de- feription of the human bones and the difeafes to which they are liable ? Many other places might be produced, where he rambles from his fubjed, without any proper or ufe- ful occafion, and jumbles together the Sceletons of Quadru- peds, Fowls,Fifties, Infeds, See. and then very gravely tells us, that if they had not All been contrived by nature, juft as they are, they would not have anfwered their feveral pur- pofes fo well. Is there a man living, who do’s not know that ? But to return to the Antra: He fays, “ Impofthumations 5* fometimes happen in thefe cavities : the figns of this dif- 8 Animadverfions on ** eate are great pain about the part, matter in the no(c on “ the fide difeafed, {linking breath and rotten teeth. Mf. “ Cow per tirft defcribed this cafe, and the cure ; which is “ performed by drawing out the laft tooth but one, or two, “ or more, if rotten, (or not rotten) and through their “ fockets making a perforation into the Antrum ; or if “ drawing a tooth makes a perforation, which fomctimes “ happens, and perhaps gave the firft hint of this cure, then “ that opening rauft be enlarged, if it is not fufikicnt to “ difcharge the matter. Dr. Highmore* mentions a Lady, who after having a tooth drawn, took her filver bodkin and thruft it into the focket, the tooth was drawn from ; but was exceedingly frighted to find it pafs, as it did, almoft to her eyes: ihe afterwards took a feather, ftript off its plumes, and thruft it up an hand’s breadth, by which (imagining it had gone into her very brain ) Ibe was fo terrify’d, that flie ran immediately to con- fult the Dr. 8cc. Mr. Co wper himfelf fays, it was merely the ftrudlure of the parts which led him to this operation. Whence it Is evident, that the hole made by drawing of a tooth, gave no hint of this operation to Dr. Highmore,&c- and that Mr. Cowper did not take the hint from the draw- ing of a tooth, as Mr. Cheselden infinuates; hut from His thorough knowledge of the ftrudlure of the parts, and the ufe to be made of them in practice. Parag 9. « Maxilla inferior, is articulated with loofc “ cartilages to the temporal bones.” The Maxilla Inferior is not articulated 'to the Os Tempo-* ris with loofe cartilages, but with ftrong burfal ligaments, and two intervening cartilage,; as will appear to anyone who pleales to confult nature. * Difyuijitio Anatom, lib. 3. Mr. Chefelden’s Bones, &c. 9 “ Chapter III. 44 Of the bones of the Trunk * He fpends near three pages in deferibing the mechanlfm of the Vertebrae mechanically ; the purport of all which, is, that if they had not been contrived juft as they are, they would not have been of fo much ufe as they are at prefent. A notable difeovery indeed ! Parag. n. “ In two children, which I have diflected, I “ found the ribs broke inwards, and on the outfide a very plain 44 print of a thumb and fingers, which had been done by their 44 nurfes hoifting them up on one hand, taking hold of their 44 breafts, and being often repeated, had broke the ribs in- “ wards like a green ftick, without feparating the broken w ends of them. I have alfo very frequently Teen the fliape “ of childrens breafts quite fpoil’d by fuch tricks, which 44 have occafioned weaknefs of body, crookednefs, and other 44 difeafes.” This is a moft ufeful obfervation ; an obfervation of far more confequence to mankind than all the reft of the book ; an obfervation which fliews what a mean, defpicable, nay, contemptible figure, all his jargonico-mechanical reafonings on the ftiapes and mechanifm of the bones, or all the fpe- cious, fine-drawn, florid Theories and Hypothefes, which have hitherto been fpun, on digeftion, nutrition, mufcular motion, the animal {pints, &c. make, when com- pared with one good pradtical obfervation, the ufe of Which appears at fight to every reader, and the ufe of Thole to none but their hatchers. “ Chapter IV. “ Bones of the upper limb.” Parag. i. 44 Clavicula is connected at one end to the M Sternum with a loofe cartilage,” The Clavicula is attached to the Sternum, by a ftrong burial ligament, but is hindered from touching it by a thick glib intervening cartilage, as in the joints of the lower jaw. Whence it is evident, that the Clavicula is not connected to the Sternum by a loofc cartilage, but by a ftrong ligament. 10 Animadverfions on “ And the other to the Proceffus Acromion of the Scapula.” But whether cottnedted alio by a loofe carrilage, lo> gitudi- nal or burial ligaments, the Herculean labourer fayeth not. « It*s chief ufe is to keep the Scapula a fufficient diftance from thebreaft, by which means thelhoulders are hindered “ from coming near together, as they do in thofe Quadru- “ peds, who ufe their lore Limbs only to walk on, and not “ as Men do their Hands.” The chief ufe of the Clavicula is undoubtedly to keep the Scapula at an equal and fufficient diftance from the Sternum, which contributes very much to the ftrength, beauty, and agility of the body. But when the Claviculae have been broke, they are feldom fo well reduced and kept in their places, but the ends ride a little when cured; whence the Scapula comes nearer the Sternum than before, by which means, the ftrength, beauty, and agility of the body are impaired. But who ever faw a quadruped who tiled it’s fore limbs Only to walk on 1 or, that walked Only on it’s fore limbs tG lave it’s hind limbs ? Who ever law a quadruped who ufed, or could ufe, it s fore limbs as men do their hands ? If our y g II s had given us the Sceletons of thcle two monfters, they would have pleafed more, than all the frightful creatures he has pick’d up, and at fo vaft and need- lefs an expence engrav’d. Parag. z. Scapula is fixed to the Sternum by the Clavicula.” I have already, pag. 9. proved that the Clavicula do’s not touch the Sternum at all; in what lenfe then can it be faid to fix the Scapula to the Sternum ? Might he not as well have faid, it fixed the Scapula to the Teeth ? Parag. laft. “ Carpus Is compofed of eight bones of very “ irregular forms, undoubtedly the propereft that can be; Mr. Chefelden’s Bones, &c. 11 M yet why in thefe forms, rather than any other, no one has “ been able to Ihew.” Here oqr author is forced to own, that his mechanicks are at a ftand: for he, nor no body elfe, can account for the me- chanical contrivance of the bones of the Carpus. A great conceflion indeed ! But who ever doubted that the forms of all the bones, as well as thofe of the Carpus, were the pro- pereft that can be ? Who, befides our author, ever pretended to account for nature’s particular views in making the bones of this or that form ? It is the bufinefs of an Anatomift, in my Opinion, to deferibe to his hearers or readers, what forms na- ture has given to the parts, which compofe the human body, and their obvious ules; but they who fuppofe Anatomifts can dive fo far into the fecrets of nature, as alfo to account for their being made of This or That figure, colour, fubftance,&c. rather than any other, muft be latisfied with very weak, idle, uncertain, nay often very impertinent conjectures, inftead of folid reafons and clear demonftrations. Cluicunque Vult • Si Populus Vult! “ Bones of the lower limb.” “ Chapter V. Parag. 2. “ Patella is feated at the fore part of the knee \ “ it?s firft appearance is in the center of the tendon, through which it foon extends, until the tendinous fibres are loft, “ and appear to be converted into bone ; however, when “ this bone is broke, the original tendinous fibres feem to prevail, feeing the broken parts, unlike all other bones “ when fraftured, unite with a tendon-like fubftance, which «* is rarely converted into a bone, and efpecially in thole “ cafes, where the joint recovers with moft motion ; it’s ulc “ is to lecure the extenfors of the Tibia, left palling over the “ joint, they might be too much expofed to external inju- “ ries; it allb encreafes the advantage of removing the com- “ mon Axis of the extenfors of the Tibia farther from the center of motion, and is a moft convenient medium for tho le •* raufcles to unite in, to perform one common aCtion.” Animadverfions on 12 Pray who can cure a fra&ure of the Patella the better for reading this jargonico-mechanical account of it ? The obfcrvations I have made on this paragraph are fo very long, that they would not fuit with the intended bre- vity of thefe remarks, but they, with many others, here omitted, ftiall be fully treated of in my own work.* Parag. 4. “ The Fibula being fo frnall, would have been “ net Itrong enough, if it had been made for more motion/’ If I had been to ufe thefe words, I fhould have faid. Would not have been ftrong enough : but if his way o* placing them is good Englifti, I’m fure it is bad Scotch. “ It would not have been ftrong enough, if it had been “ made for more motion.” But as it is made for no motion, it is full ftrong enough to anfwer all the ends it was made for. He might as well have faid, if it had been to fupport the whole weight of the body, as the Tibia does, it would not have been ftrong enough : Or, if it had been only to have fupported the weight of a pigeon, it would have been too ftrong. But there’s no end of If’s & And’s, why then won’t he be content with the parts as nature has made them 1 Parag. 4. “ It is doubtful to me, whether or not this bone, contributes to the fupport of the body ? ” If any perfon I had no knowledge of, had aflerted this, I Jhould have concluded that he had never difledted the leg, nor ever feen a fracture of the Fibula, when the Tibia was whole. If he had difl'ected thofe parts, he muft have per- ceived that the thigh bone is fo far from bearing upon the Fibula, that it do’s not fo much as touch it; but bears wholly on the Tibia. And if he had ever feen the Fibula broke, and the Tibia whole, he might have perceived that the whoie weight of the body was fupported juft as before. * fid. PropofaJs, Mr. Chefelden’s Bones, &c. 13 How then is it pofllble for the Fibula to bear any part in fupporting the body ? Where is there any room for doubt- ing ’ But if he had been at the pains to turn back to his firft account of the bones publilhcd in 1715, he would have had his doubt folved ; for there, pag. 22. he fayeth, “ Fibula tl has no lhare in fupporting the body, &c.’’ In his lecond edition 1722, &c. he fays, “ The upper end of the Fibula “ is articulated to the outfide of the Tibia, an inch below “ it’s joint.” How then is it poffible for the thigh bone to bear upon’t ’ In pag. 7. I accufed him of reading no books on the bone* but his own ; but from thefe paflages I think it is evident, he reads his Own as little as other People’s works. c< Chapter VI. He has cram’d this chapter lb full of mechanicks, that there’s hardly room for any anatomy. Parag. 10. From the edge of the Ilium to that of the “ Os Pubis, runs a ligament which is contiguous to, and “ appears to be a part of the tendons of the mulcles of the) “ Abdomen; it’s ufe is to cover the iliack veflels as they de- “ fcend to the thigh : Under this ligament, together with the veflels, I have often fecn a rupture of matter, and, I “ think, fometimes of the gut, from the Abdomen into the “ anterior part of the thigh, immediately below the groin j “ however, I dare affirm this to be a poffible cafe." From the edge of the Ilium to that of the Os Pubis, ** runs a ligament which is contiguous to, and appears to be “ a part of, the tendons of the mufcles of the Abdomen,” This is alfo called Ligamentum Paupertii, Fallopii, Hit & Pubis, &c. But Mr.CowPER, Heister, Morgagnius, &c. fay it is not a ligament, but only the tendinous border of the oblique mufcles; and Mr. Chese lden (to be fure tobe on the right fide) firft calls it a ligament, and then a tendon. But call it what you pleale, it certainly anfwers all the in- tents and purpofes of a ftrong ligament. “ Cartilages, Ligaments, &c.” 14 Anlmadverfions on «» It’s ufe is to cover the iliack veftels as they deftend to “ the thigh.” Pray what occafion was there for a ligament feveral inches long to cover the Iliack Veftels, which all lie in lels than the fpace of one inch ? Where is the mechanical contrivance here ? But if Mr. Cheselden had fpent as much time in confidering the fituation and rnechanifm of this ligament, and the ftrong Fafcia which braces it down to the Thigh, &c. as he did in contemplating the unaccountable figures of the bones of the Carpus before mentioned, he would have dif- covered, that it was not only of ufe to cover the Iliack Veffels, but was alfo the greateft prefervative in nature againft both Inguinal and Femoral Hernia’s, 8cc. fuch troublclbme, tormenting, nay, dangerous difeafes. “ Under this ligament, I have often feen a rupture of *{ matter.” A Rupture of Matter! this I take to be a Rupture of Mr. Cheselden’s own invention : becaufe I never met with it amongft all the ridiculous Names of Hernia’s mentioned by Authors, e. g. Hernia Aquofa, Carnofa, Ventofa, Humo- ralis, &c. A few years ago I had a patient, who ftiew’d me a large tumour on the infide of his Thigh, about four inches be- low this ligament. X found matter fluctuate in it; but the largenefs of the fwelling, and the ftrong impulfe it made againft my hand, when I defired him to cough, made me fafpeCf, that the gut alfo made part of the tumour: therefore, next day I confulted the late Learned and Ex- perienced Surgeon Mr. Edward Green ; who after a very ftridt examination, could not clearly determine whether the gut was there or no. However, we again two days after, and opened it; upon which there iftfued above a, quart of laudable well-digefted Pus, and neither gut nor caul appeared, but an infathomable Sinus which ran under the forementioned ligament.
