Middlemilk. 
6 milkings. 
Quarters 1 and 2 infected as above. 
® 3 and 4 yielded the same organism (albidus) only once. 
M. varians lactis found once in milk from No. 2. 
Foremilk. 
6 milkings. 
Milk from quarters 1 and 2 contained M. albidus in quantities of 
about 500 per c.c. 
M. varians was found but seldom. 
Only six plates from Nos. 3 and 4 showed no growth. 
Galactococcus versicolor, was found once in the milk of two quarters. 
Eighteen weeks later cultures of the udder tissue were made. Plates 
from the upper portion of the gland contained about 99% white cocei 
and very few yellow. Those from the lower parts had a greater per- 
centage of yellow colonies. Three plates from the latter region also 
developed colonies of other organisms. Two spore-bearing bacilli 
occurred in noticeable numbers, and one colony each of a red torula 
and B. fiworescens liquefaciens also appeared.

Strippings. 
4 milkings. 
M. acidi lactis and M. varians lactis of variable occurrence, one or 
both being present on the milk of quarters 1, 2 and 4. 
Milk from No. 3 developed no growth on the plates. 
Middlemilk. 
4 milkings. 
All quarters contained varying quantities of the same germs. 
Foremilk. 
4 milkings. 
The same organisms occurred. 
The udder tissue, when examined nine weeks later, contained 98%
