To
J. MacQueen, F.R.C.V.S.,
PROFESSOR OF SURGERY AT THE ROYAL VETERINARY COLLEGE, LONDON,
AS A SLIGHT ACKNOWLEDGMENT OF HIS ABILITY AS A TEACHER,
AND IN RETURN FOR MANY KINDLY SERVICES,
THIS VOLUME IS GRATEFULLY INSCRIBED BY
THE AUTHOR.
PREFACE
Stimulated by the reception accorded my 'Common Colics of the Horse,' both in this
country and in America, and assured by my publishers that a work on diseases of the
foot was needed, I have been led to give to the veterinary profession the present
volume.
While keeping the size of the book within reasonable limits, no effort has been
spared to render it as complete as possible. This has only been achieved by adding to
my own experience a great deal of the work of others. To mention individually those
who have given me permission to use their writings would be too long a matter here.
In every case, however, where the quotation is of any length, the source of my
information is given, either in the text or in an accompanying footnote. A few there
are who will, perhaps, find themselves quoted without my having first obtained their
permission to do so. They, with the others, will, I am sure, accept my hearty
thanks.
The publishers have been generous in the matter of illustrations and diagrams, and
although to the older practitioner some of these may appear superfluous, it is hoped
they will serve to render the work an acceptable textbook for the student.
