Disease set up in Various Animals by T. pecorum, Nyasala.nd — The Wild- 

 game Strain. 



Cattle. — No cattle were available for experiment. 



Goats. — As might be expected, T. pecorum from the blood of antelope 

 behaves in the same way to goats as that from cattle. It has the same 

 virulence, gives rise to the same symptoms and post-mortem appearances. 



Monkeys. — The monkey is an animal not very susceptible to T. pecorum.
