May 4, 1915, this animal developed a diarrhoea which lasted 

 but one day. 



May 21, 22, and 23, this animal again developed a diarrhoea, but 

 did not present a high temperature and soon returned to normal. 



August 24, 1915, bull 3839 was inoculated with a culture in an 

 experiment on the cultivation of the rinderpest virus, but the 

 animal failed to show any reaction to this inoculation. 



October 5, 1915, bull 3839 was inoculated with 3 cubic centi- 

 meters of virulent rinderpest blood from pig 216. 



History of pig 216 (see experiment 17) : 

 October 5: D., N. E,, vomiting. 



October 6: Died of rinderpest, presenting typical lesions of that 

 disease upon autopsy. 



October 9, bull 3839 presented a morning temperature of 

 39.8° C. 



October 12, 13, and 14, D., N. E. 



October 15, died of rinderpest, presenting typical lesions of 

 that disease upon autopsy. 



EXPERIMENT 32 



Cow 3958. — Known history prior to the experiment: Native 

 Batanes cow, 2 years old, received at the laboratory and placed 

 in quarantine October 1, 1915. This animal was kept under 

 observation ten days before it was used. 



October 5, D. The animal did not possess a temperature, 

 however, and the bowels were normal the following day. 



October 10, 1915, cow 3958 was inoculated with 50 cubic 

 centimeters of virulent rinderpest blood from pig 217. 



History of pig 217: 



Contracted disease by exposure to sick pigs. 



October 8: First rise in temperature, registering, a. m., 39.7' 



C; p. m., 41" C. 

 October 11: D., E. L. 



October 14, cow 3958 presented a morning temperature of 

 39.3° C. ; afternoon temperature, 40.4° C. 



This animal showed a high temperature until October 22, 

 when its temperature subsided to normal. It did not develop 

 inappetence or diarrhoea during the course of the disease and 

 was proved immune by subsequent exposures in the shed where 

 the animals sick with rinderpest were kept. 



In summing up the results obtained in experiments 29 to 32, 

 inclusive, it will be noted that cattle readily contract rinderpest 

 when inoculated with blood taken from pigs sick with that 

 disease.
