Bacillus of bubonic plague: A, in pus from suppurating bubo; B, the 

 bacillus very much enlarged to show peculiar polar staining. 



It is demonstrable in cover-slip preparations made 

 from the pus and in sections of the glands by the ordi- 

 nary staining-methods. 



Wilm ^ has found it by culture methods in the spleen, 

 lungs, liver, kidneys, stomach, walls of the intestine, 

 urine, and intestinal contents of fresh cadavers ; and 

 during life in the blood, expectoration, fseees, and urine 

 of patients sick of plague. He failed to find it in the 

 perspiration.
