Table IX. — Cell and Bacterial Counts of Chloe B. (No. 7). 



Cell counts made from single streams of milk drawn about the middle of the milking. 

 Bacterial counts from the strippings. Numbers given per cubic centimeter. 



table shows that there is no close relationship between the number 

 of bacteria and the cell counts even where these are taken under 

 the most favorable circumstances for detecting such a relationship. 

 Of the two right quarters which discharged very few cells, one had 

 a very low bacterial content but the other gave the highest average 

 bacterial content of all four quarters. The highest bacterial count 

 obtained was found in this quarter (right hind on March 14) at 

 a time when the number of cells discharged was only 10,000 per 

 cubic centimeter. The two left quarters which were discharging 

 cells by the hundreds of thousands per cubic centimeter had average 

 bacterial counts of 317 and 205. In this case the quarter with 

 the lower count discharged more than twice as many cells as the 

 quarter with the higher count. 



No streptococci could be demonstrated by microscopic examina- 

 tion of the colonies which grew on the agar plates. The increase 

 in count at 37 degrees C. in both of the left quarters was largely 

 due to a single species of micrococcus which was by far the 

 most abundant organism present. This organism was identified 

 by Wilson as being one of the common udder micrococci and 

 probably the same as the one which Harding and Wilson have
