XI, B, 5 Boynton: Rinderpest in Sioine 227 



EXPERIMENT 11 



Pig 186. — Known history prior to the exposure: This animal 

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

 to the laboratory and placed in quarantine on March 2, 1915, 



On May 2, 1915, this animal was inoculated with 50 cubic 

 centimeters of blood from a pig suffering from hog cholera. 

 This blood had been passed through a Berkefeld N. filter. The 

 animal developed a mild form of hog cholera and recovered. At 

 no other time than when suffering from the mild attack of hog 

 cholera did the animal have a rise in temperature or show any 

 symptoms of sickness. 



May 26, 1915, pig 186 was exposed to pig 185 in corral No. 1 ; 

 this was the second day of temperature for pig 185. The ex- 

 posure was continued for sixteen days. 



History of pig 185 during the exposure: 



Referring to experiment 1, it will be noted that pig 185 contracted 



the disease from bull 3906. 

 May 26: Temperature, a. m., 39.1° C; p. m., 40.5° C. 

 May 27: Temperature, a. m., 40.2° C; p. m., 40.9° C. 

 May 28-31: N. E. 

 June 1-9: E. L. 



May 30, pig 186 developed a rise in temperature, registering, 

 in the morning, 39.8° C. ; in the afternoon, 40.6° C. This was 

 four days after the initial exposure to pig 185. 



May 31, afternoon temperature, 41.6° C, which was the 

 highest temperature registered during the course of the disease. 



June 1-4, D., N. E. 



June 9-10, D., E. L. 



June 15-16, D. 



This animal gradually recovered, but did not become thrifty, 

 and was killed August 7, 1915. 



EXPERIMENT 12 



Pig 212. — Known history prior to experiment: This animal 

 was a native pig, 5 months old, purchased in Manila and kept 

 in quarantine eight days before it was used. On the first day 

 in quarantine it registered an afternoon temperature of 40.4° 

 C, which was undoubtedly due to excitement, since the tem- 

 perature subsided to normal on the following day and remained 

 so until after it was used, and at no time prior to the exposure 

 did it manifest any symptoms of sickness. 



July 27, 1915, pig 212 was exposed to pig 208 in corral No.
