PREFACE. 



by the Department of Agriculture, placing the annual 

 loss of live stock in the United States by disease, at 

 more than $100,000,000, From experience, I am sure 

 that a large part "of this immense loss can be avoided, 

 and it has been my aim to give the necessary advice 

 which will eventually lead to the saving of a very large 

 percentage of the domestic animals which at present 

 die from preventable or curable diseases. 



The insertion of the section relating to the adminis- 

 tration of medicines, with an alphabetical table of dis- 

 eases and their remedies and the table relating to medi- 

 cines and their doses was suggested to me by Dr. J. A. 

 Breakall, for which I thank him. My brother, Dr. A. 

 M. Heard, has also rendered valuable aid in many ways 

 which I cannot here specify. I also thank Mr. George 

 Kittredge for the interest he has taken in making the 

 drawings for several of the illustrations, and Messrs. 

 Clarke and Richardson, for the loan of valuable cuts.
