Although many of the reforms proposed in anatomical nomen- 

 clature are truly admirable, yet, not having been generally adopted, 

 their employment in this work would, it is to be feared, cause confusion, 

 and lessen its value as an introduction to human anatomy. 



An experience of ten years with anatomical and biological classes 

 has led to the conviction that the processes of development can be best 

 understood after the adult structure is thoroughly mastered. Then, 

 and not until then, can the study of embryology, with the aid of the 

 microscope, abundant embryological material, and appropriate methods, 

 be successfully pursued. It is proposed, therefore, to consider embry- 

 ology together with histology in a succeeding volume of the series. 



The illustrations of human osteology have been taken from other 

 treatises ; all the illustrations of the bones of the cat have been drawn 

 and engraved expressly for this work. Unless otherwise noted, these 

 drawings represent the objects enlarged to twice the natural size. To 

 save time, the same figure is occasionally repeated. 



Although errors must lurk in a work embracing so many details, 

 all the statements have been made from personal observation and many 

 of them repeatedly verified. 



I am indebted to Mr. Joseph McCreery for the skill and vigilance 

 with which he has read the proofs of these pages, and for many 

 criticisms and hints of which I have gladly availed myself. 



The remaining volumes of the series are in preparation, and will 

 be issued as rapidly as possible.
