PREFACE 



If veterinary science is to attain its justly deserved place 

 in the agricultural college curriculum, it must be so presented 

 as to bring out the close relationship that should exist between 

 it and the natural and physical sciences now taught. 



In this book are incorporated the writer's ideas of the manner 

 in which this object may be accomplished. The text differs 

 from those on veterinary science at present available to agri- 

 cultural students in that it places greater emphasis upon the 

 important subjects of anatomy and physiology. 



No attempt has been made to treat in great detail the various 

 subjects considered, the scope and purpose of the book being 

 to present the more important facts rather than those of highly 

 technical character. The aim has been to select from the im- 

 mense amount of material available that most suitable for 

 agricultural students. 



In Part I the structure and functions of the animal body 

 have been described in such a way that the student may readily 

 use the information in judging animal form, capacity, and pro- 

 ductivity, as well as in the problems connected with the feeding 

 and breeding of animals. In Part II the student is shown how 

 to recognize sickness in animals, render first aid treatment, 

 and prevent diseases. 



The reason for presenting basic facts relative to the chemistry 

 of the body in the first chapter is that experience shows that 

 students do not appreciate the principles of veterinary science 

 unless they have some knowledge of chemistry. Those who 

 have had only an introductory course in chemistry, or are taking 

 the subject at the same time they are studying veterinary science, 

 should have no difficulty in grasping the facts that it has seemed 

 desirable to include. 



This edition is a development of the author's former publica- 

 tion entitled, "The Horse in Health and Disease.'' The title
