DISEASES of the pig" have not been hitherto adequately 

 represented in veterinary literature as they should have 

 been, especially in this country w^here the growing of pigs is 

 one of the principal industries, represented by hundreds of 

 thousands of dollars. I have been surprised that some of my 

 professional brethren have not taken up this vv^ork, but I sup- 

 pose that lack of time and opportunity prevented them from 

 so doing. Some ten years ago I was urged by some of my 

 friends to undertake such work, but having so little literature 

 on the subject to cull from, I hesitated to do so, but since com- 

 ing to Illinois T have had ample opportunity of investigating 

 all the diseases of swine. 



The subjects dealt with are based on science and confirmed 

 by experience, so that the reader will not lose time in reading 

 theories which are not confirmed by facts. There are a few 

 diseases of swine, such as thumps, partial paralysis of the hind 

 quarters and canker of the mouth, which will in the majority 

 of cases prove fatal. These diseases have been thoroughly in- 

 vestigated and the proper remedies discovered, and if adminis- 

 tered as set forth in this treatise the majority of the affected 

 pigs will recover. I have, with the assistance of Doctor Burrill, 

 Professor of Bacteriology in the University of Illinois, investi- 

 gated extensively "hog cholera," and have made considerable 

 headway in treating the disease successfully. These results 

 and treatment will be found in this volume. It also contains 

 as an introduction an article on the health of the pig which 

 will be of great service to the swine breeder. The book con- 

 tains a number of illustrations which will be helpful to the 

 reader. My hope is that this manual will fill a long felt want 

 to the veterinary surgeon and swine grower.
