previous experience, is more apt to manifest itself 
when we deal with lower incubating-temperatures, as 
from 77°-96° F. (25°-35° C.), rather than with 122° F. 
The fermentation which takes place in boiled or 
superheated urine is altogether different from that 
which occurs in unheated urine in open vessels.

Even when the fluid has become quite turbid, it is 
never fcetid. The odour may be either quite un- 
altered in this respect or, at most, there may be a 
slight increase of its urinous character.!. As a rule, 
1 In partly neutralised diabetic urine which has undergone fermenta- 
tion in an airless vessel, I have on two or three occasions found an ex- 
treme fcetidity of the fluid ; and this is, moreover, an extremely common 
occurrence where turnip-infusion ferments under the same conditions.
