of the disease and which have been found in cattle and carabaos 

 under similar conditions. However, the animal had an incuba- 

 tion period that corresponded to that of rinderpest. 



In experiment 16, pig 219 ran a typical course of rinderpest 

 and recovered with the after effects of being unthrifty, which 

 condition is frequently noticed in pigs after they have recovered 

 from rinderpest. 



PIGS INOCULATED WITH VIRULENT BLOOD FROM CATTLE SICK WITH 



RINDERPEST 



The following experiments were designed to furnish informa- 

 tion regarding the possibility of pigs contracting rinderpest 

 by inoculating them with blood taken from cattle sick with 

 rinderpest. The animals that were inoculated were kept in 

 screened stalls in a shed, which was free from disease, until 

 they developed a rise in temperature, at which time they were 

 removed. 



EXPERIMENT 17 



Pig 216. — Known history prior to the experiment: This 

 animal was a native pig, 7 months old, purchased in Manila 

 and kept in quarantine seventy-two days before it was used. 

 At no time during this period did it develop a temperature 

 or show any symptoms of disease. 



September 30, 1915, pig 216 was inoculated with 6 cubic 

 centimeters of virulent blood from bull 3925, which was on 

 its second day of temperature. 



History of bull 3925: 



September 25: Inoculated with 200 cubic centimeters of virulent 



blood from bull 3937. 

 September 28 : First rise in temperature, p. m., 40.4" C. 

 September 30: Second day of temperature, blood was taken to 



inoculate pig 216. 

 October 1-3: D., N. E. 

 October 3: Died of rinderpest, presenting tjrpical lesions of that 



disease upon autopsy. 



October 3, pig 216 developed a rise in temperature, registering, 

 in the morning, 40.5° C; in the afternoon, 41.1° C; this was 

 three days after the inoculation. 



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



October 6, died of rinderpest, presenting marked lesions of 

 that disease upon autopsy. This pig was used in exposure 

 experiments 13 and 26.
