1 PLAGUE CULTURE ON BONE. 
Plague will not live long on a piece of dry bone, for a bouillon cul- 
ture saturated on small porous bits soon died out. 
An old dried femur of an ox was broken into bits and sterilized by 
heat, then saturated with a three-day bouillon culture and exposed in 
the usual manner in a Petri dish, under ditferent temperature conditions.
