EXPERIMENT 22 



Pig 24-3. — Known history prior to the experiment: This an- 

 imal was a native pig, 6 months old, purchased in Manila and kept 

 in quarantine ninety-two days before it was used. At no time 

 during this period did it register a high temperature. On 

 January 10 and 11 it had diarrhoea, which immediately subsided 

 and was undoubtedly due to dietetic conditions. 



January 18, 1916, pig 243 was drenched with 50 cubic centi- 

 meters of virulent rinderpest blood, procured from a carabao 

 sick with rinderpest from Pampanga Province. 



January 22, pig 243 presented a rise in temperature, register- 

 ing, in the afternoon, 40.2° C. ; this was four days after it had 

 received the drench. 



January 23, morning temperature, 41.0° C. 



January 24, bled to death for virulent blood to be used in 

 immunization work. 



In summing up the results of this experiment, it will be noted 

 that a pig will contract rinderpest when drenched with virulent 

 rinderpest blood taken from a carabao sick with rinderpest. 



CATTLE EXPOSED TO PIGS SICK WITH RINDERPEST 



The following experiments were designed to furnish informa- 

 tion regarding the possibility of cattle contracting rinderpest 

 when exposed to pigs sick with rinderpest. 



The experiments were conducted in corrals Nos. 1 and 2 and 

 in stall No. 1. 



The cattle used in these experiments were obtained from Ba- 

 tan Island. As, to our knowledge, there has never been any 

 rinderpest on this island, these cattle are highly susceptible. 



EXPEailMENT 23 



Bull 3908. — Known history prior to the experiment: Native 

 Batanes bull, 5 years old, received at the laboratory and placed 

 in quarantine March 13, 1915. This animal was kept under 

 observation seventy-four days before it was used, and at no 

 time during this period did it present a high temperature or 

 develop any symptoms of sickness. 



May 26, 1915, bull 3908 was placed in corral No. 1 with pig 

 185, which was on its second day of temperature (see experiment 

 1), and the exposure was continued for fifteen days. 



May 30, bull 3908 was also in contact with pig 186, first day 

 of temperature (see experiment 11), and the exposure was 

 continued for twelve days.
