Pig 2M.1. — Known history prior to the experiment: This 

 animal was a native pig 6 months old, purchased in Manila 

 and kept in quarantine one hundred fifteen days before it 

 was used. It developed a high temperature on October 26, 1915, 

 and was taken out of the quarantine shed and isolated. It de- 

 veloped a diarrhoea October 28, which lasted until November 

 7, when the diarrhoea subsided, and the temperature gradually 

 returned to normal. During this period the animal presented 

 a clinical picture of a mild case of hog cholera. November 26 

 pig 241 was returned to the quarantine shed, where it remained 

 until it was used, and did not show a rise of temperature or 

 any symptoms of sickness. 



February 7, 1916, pig 241 was inoculated with 25 cubic cen- 

 timeters of virulent rinderpest blood drawn from bull 3962, 

 which was on its third day of temperature. Pig 241 was placed 

 in a screened stall in a shed free from rinderpest. 



History of bull 3962: 



February 1, 1916: Bull 3962 was inoculated with 100 cubic centi- 

 meters of virulent rinderpest blood from bull 3960. 



February 4: Bull 3962 developed a rise in temperature, register- 

 ing, a. m., 39.8° C; p. m., 40.6° C. 



February 5-8: D., N. E. 



February 8: This animal presented a subnormal a. m. tempera- 

 ture of 35.8° C, and died, presenting typical lesions of rinder- 

 pest upon autopsy. 



On the day the blood was drawn to inoculate into pig 241, this 

 bull had diarrhoea and was not eating. 



February 10, pig 241 developed a rise in temperature, regis- 

 tering, in the morning, 40° C; in the afternoon, 41.3° C; this 

 was the third day after inoculation. 



February 13, N. E. 



Pig 241 died during the night of February 13 and presented 

 typical lesions of rinderpest upon autopsy.
