AND OTHER FERMENTATIVE CHANGES 307 
3. It shows that the corpuscular form of such an organism may differ in 
fermentative energy from its filamentous parent. 
4. That the corpuscular habit of growth acquired in one medium may be 
retained for a considerable time after the organism has been restored to a habitat 
in which the corpuscular form did not originally present itself. 
5. That when placed in a more favourable medium, the toruloid variety 
may reproduce the purely filamentous. 
6. This plant is another instance of an organism which is not bacteric, 
giving rise to a putrefactive fermentation in urine. 
7. It proves that an albuminous liquid may be affected with a fermentation 
with inodorous products. 
Lastly, The trustworthiness of the method of investigation is strikingly 
confirmed by the fact, that in none of the glasses of Pasteur’s solution, urine, 
or albuminous fluid inoculated with this oidium, and in neither of the glass 
gardens, did bacteria, or any other kind of fungus besides the one intentionally 
introduced, make their appearance during the entire month in which the obser- 
vations were made.
