152 TRANSACTIONS OF THE [APR. 13, 
84. BACILLUS ZETA. 
The cultures are dead. 
102. BAcILLUS M. FUSCUS CONSISTENS. 
Nitrate was not reduced and the growth was not distinctly 
wrinkly. Otherwise the same. 
110. BAcILLUS FUSCUS LIQUEFACIENS. 
Unchanged, except that the nitrate was not reduced. 
112. BAcILLUS KAPPA. 
Rosalie acid decolorized as before. Milk peculiarly affected. 
It is not coagulated at first, but in 23 days the whole mass re-- 
sembles a starch paste, on boiling becoming jelly-like with thick 
flocculi. Otherwise the same. 
114. Bacittus PLYMOUTHENSIS. 
Exactly as in B..rosaceus metalloides. The growth is no 
longer viscous. Lactose litmus agar is not reddened by this 
species, which would seem to show that the reddening of the 
lactose-litmus gelatin was due to some product of the liquefied 
gelatin. 
116. Bacitius Kram. 
Apparently overgrown by a contamination. 
117. BACILLUS LARVACIDA. 
Unchanged. 
120. BACILLUS PYOGENES FETIDUS LIQUEFACIENS (Lanz).* 
Nitrate completely reduced in 28 days. Rosalie acid is 
deepened in color. Otherwise as before. 
121. Bactttus PRUDDENI. 
Unchanged. 
123. Bacttitus BooKkert. 
The lactose litmus agar, while reddened at first, ultimately be- 
came blue. The nitrate was strongly reduced as before, and the 
other characters were the same. 
126. BACILLUS SORDIDUS. 
Unchanged. 
I draw the following conclusions from the results of these re- 
plantings. 
(1) Species under long cultivation, such as I have received 
from collections, tend to be constant in their characters.
