 Animals. 



Inoculate agar-slants from stock-culture of B. cuni- 

 culicida. For obvious reasons, B. pestis will not be 

 studied culturally. 



1. Routine study. — Stain with Loeffler's methylene- 

 blue and anilin-gentian-violet. Observe "polar stain- 

 ing." What is "polar staining" ? 



2. Special study. — Inoculation of rabbit subcutane- 

 ously or by scarification. When dead, study in the 

 usual manner, and observe particularly the hemorrhages 

 produced in the serous membranes. Make cultures 

 from heart's blood, where large numbers of bacilli will 

 be found. Also make a stained preparation, and note 

 the typical polar staining.
