About 15 very.small nodules found in lungs, all deep seated, and following 

 Ihe main bronchial tubes, mostly encysted. 



Three guinea pigs inoculated 7-12- '04. From one pure cultures of bacillus' 

 mallei were obtained. 



In all these autopsies there was noted the peculiar injected appearance of 

 the lungs which, is seen when a reacting animal is des1;royed immediately after 

 testing. In all but one of these five ceased reactors a pure culture of the 

 fcacillus malld was obtained. In this case the lesions found were characteristic, 

 and it is probable that the bacilli were present. Only two guinea pigs were 

 sised for this inoculation. ' , , 



The following very striking; record is that of a horse which has, ceased to 

 ^ react no less than three times in the course of the last three years. This animal 

 ■is still isolated under close supervision, and although performing ordinary farm ■ 

 •«v6rk daily, is in the pink of condition, and, to all outward appearance, abso- 

 lutely healthy: ,

I append here three tables showing the different results obtained in testing, 

 1st, horses which have become permanent ceased reactors; 2nd, horses which 



after having once ceasfed to react, have again given a characteristic reaction to 

 Mallein after a period of froin six months to a year ; and 3rd, horses which have 



shown lie improvement when tested at intervals of 30, 60 and 90 days, although 



never developing clinical symptoms.
