Boynton: Rinderpest in a Carabao 



47 



the day before, but did not contract rinderpest. The suscepti- 

 bility of these three animals to rinderpest was proved later by 

 their becoming infected with the disease on exposure in other 

 experiments, 



CONCLUSIONS 



1. From the facts of this case, the evidence is conclusive that 

 an animal may experience a fatal attack of rinderpest without 

 the occurrence of a rise in temperature. 



2. The blood of carabao 3235 was shown to be infected within 

 forty-eight hours after it was originally injected with virulent 

 blood. 



3. It was shown that the blood was virulent on the eleventh 

 day when injected into a susceptible animal, yet exposure to the 



^.3235.

same animal from which blood was drawn did not cause rinder- 

 pest in the exposed susceptible animal. 



4. With regard to the three animals which failed to contract 

 rinderpest by exposure, the question is raised as to whether 

 rinderpest spreads by contact readily in the later stages of the 

 disease or whether the disease must necessarily be accompanied 

 by a rise of temperature before it can be spread by contact.
