NOTE. 



While lecturing on the diseases of the dog the writer recognized 

 the fact that there was not in existence a work that could really 

 be called a text-book for the student and the practitioner; there 

 were then, and have been issued since, a number of "popular" 

 works that endeavored to fill the dual role of text-book for the vet- 

 erinarian and a "Dog Book" for the layman ; these, as a rule, have 

 been inadequate for the former and confusing to the latter. With 

 the purpose of supplying this want the writer, several years ago, 

 began to write a book on the subject, but two years ago read this 

 work by Professor Miiller, and instantly recognized its value as a 

 text-book: every detail in the diseases of the dog being carefully 

 considered, and the whole so admirably arranged that the student 

 can readily find and study any subject in a clear and condensed 

 form. 



He secured from the author the right of translation, and has 

 made it as exact as possible, perhaps in some parts too literal, but 

 has done so in the endeavor to closely follow the original. He 

 has also added, in the proper places, the results of his own obser- 

 vations, and also everything of value that has been added to 

 veterinary science since the appearance of Dr. Miiller' s work, 

 thus making a second and much enlarged edition. 



The metric system, as in the German work, has been followed, 

 with the hope that its use may be a slight aid to the general adop- 

 tion of what may be the future international system of measure- 

 ment.
