EXPERIMENT 25 



BlUl 3935. — Known history prior to the experiment: Native 

 Batanes. bull, 2 years old, received at the laboratory and placed 

 in quarantine June 16, 1915. This animal was kept under ob- 

 servation forty-one days before it was used, and at no time 

 during this period did it present a high temperature or show 

 any symptoms of sickness. 



July 27, 1915, bull 3935 was exposed in corral No. 1 to pig 

 208, which was on its fifth day of temperature. This exposure 

 was continued for sixteen days. This bull was also exposed 

 on August 1 to pig 212 on the first day of temperature. This 

 exposure was continued for eleven days. 



History of pig 208 (see experiment 3) : 



July 27: It presented an a. m. temperature of 39.5° C. and a p. m. 



temperature of 41.2' C. 

 July 31-August 7 : E. L. 

 August 3: It presented a p. m. temperatmre of 41.6° C, which 



was the highest temperature registered during the course of the 

 . disease. 



August 8-11: D., E. L. 

 Augrust 12: Died of rinderpest, presenting typical lesions of that 



disease upon autopsy. 

 History of pig 212 (see experiment 12) : 



August 1: Temperature, a. m., 40.6° C; p. m., 41.6° C. 



August 3-7: E, L. 



August 9-11: D., N. E. 



August 11: Died of rinderpest, presenting typical lesions of that 



disease upon autopsy. 



Bull 3935 did not show a rise in temperature or develop any 

 symptoms of sickness from these two exposures. 



September 16, 1915, bull 3935 was inoculated with 100 cubic 

 centimeters of virulent rinderpest blood procured from a sick 

 carabao in Pampanga Province. 



September 20, bull 3935 presented a morning temperature of 

 39.6° C. and was bled to death for virulent blood to be used in 

 immunization work. 



EXPERIMENT 26 



Bull 3886. — Known history prior to the experiment: Native 

 Batanes bull, 3 years old, received at the laboratory and placed 

 in quarantine November 7, 1914. This animal was kept under 

 observation three hundred thirty-two days before it was used 

 in this experiment, and at no time during this period did 

 it have a high temperature or show any symptoms of sickness. 



It had been used in two previous experiments which were as
