Table X — Cell Content of the Milk of Ruth F. B. B. (No 25). 

 (A Grade Jersey heifer which freshened March 13, 1911.) 



front, 218; right hind, 14; left front, 16; left hind, 5; average of 

 the four quarters, 62. 



These figures are all low when compared with those found by 

 other investigators. An examination of the colonies on the agar 

 plates showed a micrococcus to be present in the right front quarter 

 of this cow which was apparently the same as that present in the 

 left quarters of Chloe B. (No. 7), but this form was not present in 

 large numbers. There were no streptococci which grew on the 

 plates. The samples of milk from which the plates were made 

 were incubated as before for 3 days at 37 degrees C. and then examined 

 microscopically. No streptococci were found.
