PREFACE TO THE SECOND: EDITION. 
When the first edition of this book was published less 
than a half dozen medical schools in the United States 
required the entering student to have any knowledge of the 
structure of the lower animals. To-day a knowledge of 
mammalian anatomy or zoology is considered one of the 
first requisites for entering upon an intelligent study of 
medicine. The signs of the times indicate that in the near 
future no medical school will receive students without some 
practical knowledge of the structure of a mammal. 
That the students of modern psychology, the teachers of 
physiology in all high schools and the directors of all 
gymnasiums need a definite knowledge of the essentials of 
the anatomy of a mammal, is becoming more and more 
evident. These facts and the steady demand for the first 
edition of this book have been the principal factors in 
determining the preparation of a second edition. 
Owing to the gradual acceptance, in part at least, of the 
B. N. A. nomenclature, numerous changes have been made 
in the body of the text. The names used in this edition are 
such as have found favor with the majority of American 
anatomists. The author’s easy and quick method of prepar- 
ing the skeleton for study is for the first time presented 
in print. Jn several instances the language has been made 
more clear, and several new figures and a glossary have 
been added which will be of special help to the beginning 
student of anatomy.
