DISEASES OF CATTLE. 



To make this work more complete, I will add a disserta- 

 tion on the Diseases op Cattle, dwelling more especially 

 on epidemic diseases and their treatment, as far as may be

 all technicalities which are not generally understood by the 

 non-professional. My endeavor has been to write in a clear 

 and popular style, and with all the brevity consistent with 

 thoroughness and the demands of the practical farmer.

 disease have at the present time made their ajjpearance in 

 difierent States of the Union, I think it my duty to make 

 public the experience which I may have acquired in treat- 

 ing them. The importance of diffusing knowledge on this 

 subject is the more apparent from the fact that the diseases 

 in question undermine the wealth of whole countries, and 

 this has been recognized by the different governments, who 

 have given especial attention to the subject. I hope the 

 public will favor me with their confidence, as I have proved 

 that I am fully acquainted with the symptoms, the origin 

 and the course of the diseases. In 1866 I entered into a 

 contract with the British Minister, Sir Frederick Bruce, to
