PREFACE
All 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 generally
employed. Where there is no departure from the usual methods,
treatment that is essentially within the domain of surgery 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 difficulties 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 satisfactory and
successful part of their work; that both the practitioner 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 outlined.
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.M. Campbell; to appreciatively credit Drs. L.A. Merillat, A.
Trickett and F.F. Brown for valuable suggestions given from time to
time. Particular acknowledgment is made to Dr. Septimus Sisson,
author, and W.B. Saunders & Co., publishers of The Anatomy of
Domestic Animals, for permission to use a number of illustrations from
that work.

_Justice shows a triumphant face at the works of humane practitioners,
who give serious thought and expend honest effort, for the alleviation
of animal suffering._
