Tue publishers of the present work have long been im- 
pressed with the idea that a new book upon the Diseases 
of the Horse, written in simple language, and specially de- 
signed as a guide for non-professional readers, had grown to 
be a public uecessity. While waiting for an opportunity to 
carry this notion into effect, they were fortunate enough 
to become acquainted with a gentleman whose proficiency 
in veterinary science is undisputed. To that individual 
the present work was intrusted; and it was nearly com- 
pleted when the publishers heard with surprise that Mr. 
Mayhew employed the pencil in a manner only secondary 
to his use of the pen. 
Acting on this information, the publishers were induced 
to persuade the author to illustrate his text by drawings 
descriptive of the various stages and aspects of disease. 
The addition of above four hundred wood engravings has, 
of course, materially increased the expense of publication. 
A heavy outlay has been incurred, while, at the same time, 
the spirit of the age is decidedly against paying a large 
sum for any work of general information. These circum- 
stances render the present volume doubly hazardous. How- 
ever, it is confidently hoped that, when the accuracy of 
the illustrations and the perspicuity of the letter-press are 
appreciated, a large sale will more than recompense any 
amount of outlay.
