138 ILLINOIS STATE DAIRYMEN'S ASSOCIATION. 



Upon my suggestion Dr. Peters of the Biological Labora- 

 tory at Springfield conducted extensive experiments with Bis- 

 sulin, and as he is present I hope he will give the audience his 

 experience with this important chemical. Since this disease is 

 of highly infectious character and since its distribution in this 

 country may be very extensive, it is important that the dairy- 

 man become familiar with it and treat their animals intelligently 

 and systematically, thereby preventing the spread of this disease 

 and incidentally saving many thousands of dollars to the dairy 

 industry of this country.
