The most notable instance of decrease, as shown in the 

 above table, is in Boston. Lawrence shows a large increase, 

 15 of the cases being credited to one stable. Fall River, 

 Newton, Somerville and Worcester show an increase. The 

 increase, and in fact the larger number, in Newton, is cred- 

 ited to one sta,ble. jNIiddleborough, where there was such 

 a widespread outbreak in 1901, had only 2 cases in 1902. 

 Fitchburg, a centre of infection three or four years ago, had 

 only 5 cases in 1901 and 3 in 1902. There have been no 

 positive cases in the Berkshires, with the exception of 1 horse 

 in Cheshire. 



Mallein has been used more extensively than ever, with 

 two objects : first, to confirm doubtful physical diagnoses ; 

 and second, to enable owners to divide those that react and 

 are considered suspicious from those that do not react and 

 are considered ^ee from disease. The value of mallein used 

 in this way seems satisfactory, both to the Bureau and to 

 most of the owners. While the proof of the value of mal- 

 lein is not positive, nevertheless, it is evident that the spread 

 of glanders in large stables can be checked, not only by the 

 more careful supervision of suspected cases that is offered, 

 but possibly by the therapeutic action in checking the de- 

 velopment of the disease, — a belief advanced by several 

 good observers. 



The following table shows in detail, as far as completed, 

 the more important stables in which mallein was used to 

 divide suspected animals from others. In all cases where 

 possible, the reacting horses have been kept in a stable by 

 themselves and worked by themselves.
