76 STORRS AGRICULTURAL EXPERIMENT STATION. 
The study of the preceding table shows the following more 
important facts. 
1. There is a wide variation in the numbers of bacteria, the 
number varying from 8,000 to 2,900,000. Considering the 
fact that the milk delivered here is all supposed to be only 2 to 
12 hours old, this variation in numbers indicates a wide varia- 
tion in the conditions under which the milk is produced. 
2. With the increase of numbers of bacteria in the milk 
there is a more or less constant, but by no means regular, 1n- 
crease in the percentage of acid bacteria. This may be perhaps 
more satisfactorily shown if these figures be given in a table 
by themselves. In the following table are given in the first 
TABLE I3. 
Showing increase of percentage of acid bacteria with increase tn 
total numbers of bacteria.
