remaining clear. Then, in several of the tubes the 
fluids, to my surprise, grew rapidly turbid through-

change, were saved therefrom by being removed from 
the incubator to a cool drawer ; and some of them

in which the contents had become turbid, and which 
had in the interval been also put aside in a drawer. 
I then found the fluid more than usually aeczd, 
swarming with short Bacilli; while, much to my
