PREFACE 



AH that can be known on the subject of lameness, is founded 

 on a knowledge of anatomy and of the physiology of locomotion. 

 Without such knowledge, no one can master the principles of 

 the diagnosis of lameness. However, it must be assumed that 

 the readers are informed on these subjects, as it is impossible 

 to include this fundamental instruction in a work so brief as 

 this one. 



The technic of certain operative or corrective procedures, has 

 been described at length only where such methods are not gener- 

 ally employed. Where there is no departure from the usual 

 methods, treatment that is essentially within the domain of sur- 

 gery or practice is not given in specific detail. 



Realizing the need for a treatise in the English language 

 dealing with diagnosis and treatment of lameness, the author 

 undertook the preparation of this manuscript. That the dif- 

 ficulties of depicting by means of word-pictures, the symptoms 

 evinced in baffling cases of lameness, presented themselves in 

 due course of writing, it is needless to say. 



It is hoped that this volume will serve its readers to the end 

 that the handling of cases of lameness will become a more satis- 

 factory and successful part of their work; that both the prac- 

 titioner and his clients may profit thereby; and last but by no 

 means least, that the horse, which has given such incalculable 

 service to mankind and is deserving of a more concrete reward, 

 will be benefited by the application of the principles herein out- 

 lined. 



In addition to the consultation of standard works bearing on 

 various phases of the subject of lameness, the author wishes to 

 thankfully acknowledge helpful advice and assistance received 

 from the publisher. Dr. D. ]\I. Campbell ; to appreciatively credit 

 Drs. L. A. Merillat, A. Trickett and F. F. Brown for valuable 

 suggestions given from time to time. Particular acknowledg- 

 ment is made to Dr. Septimus Sisson, author, and W. B. Saun- 

 ders & Co., publishers of The Anatomy of Domestic Animals, 

 for permission to use a number of illustrations from that work.
