Boynton: Rinderpest in Swine 



225 



January 30, 1916, pig 242 was exposed in stall No. 2 for three 

 days to bull 3960, which was on its fourth day of temperature. 



History of bull 3960 during the exposure: 

 January 30 : Fourth day of temperature. 

 January 31 : D., N. E. 



February 1: Died of rinderpest, representing typical lesions of 

 that disease. 



February 2, 1916, pig 242 developed a morning temperature of 

 39.8° C, and an afternoon temperature of 41° C. ; this was 

 three days after the initial exposure. 



February 4-5, E. L. 



February 6-7, N. E. 



Februaiy 7, died of rinderpest, presenting typical lesions of 

 that disease upon autopsy.

In summing up the results of the ten preceding experiments 

 on the exposure of pigs to cattle sick with rinderpest, it will 

 be noted that all the pigs contracted a disease and developed 

 S5Tnptoms characteristic of rinderpest in cattle and carabaos. 



Three of the animals developed their initial rise in temperature 

 on the third day, four on the fourth day, one on the seventh day, 

 one on the eighth day, and one on the ninth day of exposure. 

 From this it will be noted that the incubation period of rinderpest 

 in pigs that have been exposed to cattle sick with that disease 

 corresponds very closely to the incubation period in cattle and
