BONES, MUSCLES AND LIGAMENTS THE OF THE DOMESTIC OAT {Felis Catis Linn.). INTRODUCTION. In the preparation of this little work the attempt is made to fur- nish, in a concise and convenient form, the means of learning the characters and scientific nomenclature of the bony frame-work, the ligaments and the muscles of a typical vertebrate animal. The common domestic Cat has been selected as peculiarly well adapted to represent the anatomical structure of the higher verte- brates; and, as Straus-Durckheim has shown, it is one of the best subjects that can be found to stand as a typical Mammal. While, in general outline and in some of its special features, it is quite different from man, its structure is so similar as to make the iden- tification of homologous parts both simple and easy, when compared with those of the latter. As a type, it is even better adapted to exhibit the general laws and principles of anatomical structure among mam- mals than is the human subject. For one expecting to enter the medical profession, there can be no better method of gaining a sound scientific knowledge of man’s organ- ization and physiological functions than by beginning his studies with the investigation of an animal in which all the essential parts of his structure are represented, but with just enough variation to draw his attention forcibly to those points which he finds to be in common when he comes to the proper studies of his profession. He will thus be led IV Introduction. to observe the differences, physiological as well as anatomical, between the characters which are peculiar to the human species, and those by which man is intimately linked with mammals in particular, and, in a broader sense, with the whole animal kingdom. A second advantage to be gained by a careful and minute knowl- edge of the anatomical structure of such an animal, is that it will serve him to the furthest extent possible when he wishes to carry on physio- logical investigations. Vivisection is never allowable upon the human subject; but under certain circumstances the laws of physiological action may be investi- gated upon the brute animal while its vital functions are intact. The very science of physiology is to a great degree based upon such investigations of the Rabbit, Guinea-pig, Dog and Cat, and yet for none of these well known animals has the anatomical structure been worked out with that minuteness and fulness demanded by the present state of biological science. For the Rabbit we have the work of W. Krause (“Anatomic der Kaninschens, etc.”}, which is a very good work in so far as it gives a general view of the main anatomical parts, but it is not well enough illustrated to be of much use to the beginner when taken by itself. The convenient size for the dissecting table also adapts the Cat to the uses of the student of anatomy. Its size is such as not to make it unwieldy, nor on the other hand is it so small as to trouble the unas- sisted eye in following the more delicate parts of structure. Again, the Cat is so common that any student may obtain a subject without difficulty, and the fertility of the species provides the means for research in the direction of embryology and individual development. Its strength, agility and ferocity when tormented, will serve as checks upon any torture under vivisection, which a weaker or more timid animal might be forced to suffer under the knife of the too eager investigator. But the character which specially recommends this species as a standard example for reference and comparison, is that of its structural uniformity. Though differences in color and, rarely, of size may he found, this uniformity is so nearly universal that it is pretty certain that any decided variation from the normal anatomy of any well-developed example of the species would be marked at once as an individual pecu- liarity. In consideration of the above facts the domestic Cat seems particu- larly worthy of having its anatomy described and figured with special care and completeness. This work has been done faithfully for the Introduction. V Bones, Ligaments and Muscles by Hercule Straus-Durckheim, but the description and illustration of tire nervous, digestive and circulatory systems, with the reproduction and special secretory and excretory organs has not been accomplished. The work of Straus-Durckheim (“ Anatomic Descriptive et Comparative du Chat,” Paris, 1845), has been taken as the foundation for the present work. His outline plates are here reproduced, and so reduced as to make them of convenient size for practical use in the laboratory. His nomenclature is entirely French, and while his identification of parts has been followed to a considerable extent, the explanatory index here presented in Latin form of nomencla- ture is rather a revision than a simple reproduction of the matter in the original work, and for this the writer is in the main responsible. There are, undoubtedly, many names here adopted which may meet with objection; but if the imperfections here found shall turn the atten- tion of working comparative anatomists to the crying need of a standard and uniform nomenclature for their science, the fullest criticism will be welcomed. If found practicable this work will be followed by a descriptive vocabulary containing the synonomy, as well as a succinct description of each part herein illustrated. It is greatly to be desired that the remainder of the special anatomy of the Cat be worked up as fully as Straus-Durckheim has done for the Bones, Ligaments and Muscles, and that this species be generally accepted as a type of the Mammalian group of vertebrates; we hope this may be accomplished at no distant day. Admirable works on comparative anatomy are not wanting, and the works of Owen, Huxley and Rolleston seem to leave little to be desired in this direction. Still neither of these works is fully adapted to the needs of a beginner, though of great value in his higher studies. The best text-book for the beginner is the subject itself lying out upon the dissecting table; and while the present work will give him a nomenclature, and maps out the field he is to investigate, he will find useful, for his further guidance Dunglison’s Medical Dictionary (al- though its descriptions are confined within the limits of human anat- omy), Owen’s Anatomy of Vertebrates, or a full work on Human Anatomy, as Gray’s, but better than these in the beginning of his studies will be the help of a competent instructor to direct his work, and examine and criticise the drawings and descriptions he shall make for himself of the bearings, relations, and surfaces of bones, the attach- ments and functions of ligaments, and the relation to each other, the areas of origin and insertion of muscles, their actions, and counterac- tions. It is the Anatomy and Physiology of Man that is to be consid- VI Introduction. ered of first importance, but a human subject for the dissecting table can be obtained only by the authorized medical student. If, therefore, we are to consider a knowledge of the physical organization and the physiological action of Man as one of the desirable acquirements of a well-educated man or woman, the importance of finding some other subject, whose organization we can actually investigate with scalpel in hand, and whose functions we may watch and study while in action, is very apparent. In the animal under consideration we see this want supplied. Taking it as our “ subject,” we may gain a knowledge of Anatomy and Physiology such as books alone can give but the faintest idea. We must look to the students of vital phenomena in the physio- logical laboratory, to the work on the dissecting table, to the cannula, the myographion, and the many other implements cf modern research, to develop Comparative Anatomy and Physiology into a perfect science of Biology. As we need look less than a hundred years into the past to find the mysteries of the alchemist in the place of the exact methods and perfect results of modern chemistry, so it may be, could we turn our vision an equal distance into the futnre, we should see the knowledge of the laws of organic structure and vital phenomena so thoroughly perfected that no educated man or woman would be considered fit to assume the responsibility of living without a complete acquaintance with the prin- ciples of structure and function of every organ and part of his body, and the laboratories of chemistry and physiology would stand on an equal footing with the Latin and Greek recitation rooms in the colleges of that future.

Note.—For the convenience of those who may have access to Straus- Durckheim’s work, “ Anatomic descriptive et comparative du chat, type des Mam- miferes en general et des Carnivores en particulierP the numbering and lettering of the original plates are retained in the present work. Besides chapters on general and comparative anatomy, and full descriptions of the parts represented in the plates, Straus-Durckheim has figured, in Plate I. “Le chat savage ” (Felis cat'us), the wild, and so considered representative of the domestic cat. Also in Plates XIV. to XXV., by finely shaded engravings the same parts represented in Plates 11. to XIII., but without any lettering for reference. Only Plates 11. to XIII. are here reproduced, the others being extraneous to the purposes of this work; but the latter, as well as the very complete descrip- tions, will be found of great use to a student wishing to make a thorough study of this branch of Comparative Anatomy. 8 ABBREVIATIONS, AND SPECIAL USE OF TYPE MARKS, ETC., IN THE NOMENCLATURE. a., arteria. apon., aponeurosis, anthr., anthropotomy. add., adductor, abd., abductor.

Synonyms are set in common Roman type. An initial capital (Musculus) signifies that the anatomical part to which the name applies is individually distinct from other parts of the same anatomical structure, while the usuage of a small or common initial letter (processus,nervus) signifies that the name refers to an extension, cavity, or other physical or formal character of such an in- dividual part. Quotation marks “ ” show that the name is adopted provisionally. Parenthes marks (—) enclosing part of a name, point to such a part as specially used by some author, or as unnecessary, or else (when it stands in light face type, at the end of a name) as simply explanatory, though not necessary in ordinary application of the name. Personal names, or abbreviations of them, affixed to a name designate the original author of the name, though in all cases where the original name was not expressed in Latin, the Latin form is assumed. A Latin nomenclature is used, as being the only form universally recognized by scientific men, and with the hope that by this means some assistance may be given towards the formation of a uniform and systematic no- menclature for comparative anatomy.
