old felons, indeed, which have so often been severely 
mauled in being driven from the communities they 
were plundering that all the hairs of their bodies had 
been pulled out — is clearly, for many reasons, inaccu- 
rate. These bees I find, in every case, filled with a 
bacillus (G, Plate I.) smaller than Bacillus alvei, and 
which cultures have shown to be quite specifically 
distinct. Its length is about in., and its width

it might be mistaken for a bacterium. Its colony 
form (A, Fig. 123) is very marked. Under cultiva- 
tion, it slowly liquefies the jelly, producing a milky- 
looking mass at the top of the culture. When seen 
under a low power, the colonies have a singular kidney- 
like form, being distinctly lobulated, and appear browm 
under transmitted light. By reflected light they are 
* So called because of the black appearance induced by the loss of the 
hairy covering.
