NOTE TO THIRD EDITION. 



The present edition of this work has been entirely re- written, a 

 large amount of new material added, and every endeavor has been made 

 to bring the work up to the standard of the present day. While pre- 

 paring the manuscript of this edition the second edition of Dr. Mtiller's 

 work has appeared and has been closely scrutinized and all valuable 

 additions incorporated in this work. One portion of this work that 

 differs materially from the German is that of therapeutics. In the 

 practice of Canine medicine, where we must necessarily administer 

 medicine by force, concentration of the dose is very essential; the writer 

 cannot impress too strongly on the practitioner and student that the 

 constant aim must be to administer all drugs in doses as small and 

 compact as possible, for it frequently happens that the excitement caused 

 by the repeated administration of large amounts of decoctions and 

 infusions in nervous or highly bred animals does more harm than the 

 original disease. 



The writer is under great obligation to Dr. Preston Hoskins for his 



suggestions and his careful reading of the proof; to Drs. Spang, Sommer 



and Jureasu for their assistance in translation, and to Dr. Meyer for his 



aid in the chapter on rabies.
