EXPERIMENT 9 



Pig 237. — Known history prior to exposure: This animal

 in quarantine seventy-five days before it was used. During this 

 period at no time did it have a high temperature or show any

 the initial rise of temperature in the bull. 



History of bull 3966 during the exposure: 



December 29: Fifth day of temperature, D., N. E. 

 December 30 : Died of rinderpest, presenting typical lesions of that 

 disease upon autopsy. 

 History of bull 3976 during the exposure: 



December 29 : First day of temperature, a. m., 39° C. 

 January 3, 1916: Bled to death for virulent blood to be used in

EXPERIMENT 10 



Pig 242. — Known history prior to exposure : This animal was 

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