 locate the cause of any trouble and more easily institute 

 measures tO' correct this. 



In order to carry out these teats thoroughly and satis- 

 factorily the laboratory should be properly equipped, and 

 have a competent trained expert in charge. We must 

 again thank your Association for the part they have played 

 in presenting the necessity for such vvoi-k and equipment

In order that he may know the contiiiuoue Bt&ie of

 should keep accurate records of each animal, breed, etc. 

 And he should isolate at once all animals suspected of any

In 1901 Koch startled the world with the assertion

 the human. 



Many and most elaborate and exhaustive experiments 

 were conducted by different obser\'ers throughout the 

 world, and these have definitely shown that the gi'eat
