A FEW words are here necessary in explanation of the system of nome: 

 clature used throughout this work. Although reluctant to add to tl 

 confusion already prevailing in the nomenclature of veterinary anatom 

 the author has not conformed to any of the systems in general us 

 The system here employed is based on the principle of naming ea< 

 object after the homologous object in human anatomy. So far, indee 

 as any of the systems in use can be said to follow a principle, it is thi 

 just stated ; but the violations of the principle are numerous, and, : 

 most cases, appear to have been dictated by the merest caprice. Tl 

 most vicious form of departure from the principle is that in whic 

 terms adopted from human anatomy are employed to designate n^ 

 the actual homologues, but other parts having, it may be, some fail 

 resemblance in shape or otherwise to the objects bearing these nain' 

 in the human subject. This method is indefensible, since it tends ■ 

 produce the greatest confusion, and, if generally adopted, would rend 

 a comparison of the anatomy of any two animals an impossibilit 

 Many such terms have long been in use, but it is hoped that they a 

 not ineradicable. 



In cases where objects appear to be without homologues in hums 

 anatomy, new names must, of course, be found. In only a few of the 

 instances, however, has the author employed terms of his own inve 

 tion, preferring, in general, to adopt some of those already in use. 



The greatest diversity of names, it will be found, exists iu the ca 

 of muscles, and the following table of synonyms has been compil 

 for the convenience of those already familiar with the terms employ 

 in some other works.
