March 27-28, D., E. L. 



March 28, died of rinderpest, presenting good lesions of that 

 disease upon autopsy.

This animal gradually recovered. 



In summing up the results of the exposure of these four 

 pigs, it will be noted that pigs can contract rinderpest from cattle 

 sick with that disease by means of the caretaker. 



PIGS RECOVERED FROM RINDERPEST, AND THIS IMMUNITY TESTED 



TOWARD THAT DISEASE 



The following experiment was designed to test the immunity 

 of pigs to rinderpest after they had recovered from that disease. 

 These animals were kept in the shed where the animals sick 

 with rinderpest were placed, which gave them frequent expo- 

 sures to animals sick with rinderpest in all stages of the disease. 



EXPERIMENT 41 



In this experiment pigs 94, 266, 267, 289, 291, 297, 301, 302, 

 155, and 154 were used.
