68 



Report of the Department of Bacteriology of the 



uniform. With the exception of the results from Millie F., which 

 were slightly higher than the others, there were only 5 milkings out 

 of 88 where this number given under the head of difference amounted 

 to more than 1000 germs per cc. 



For convenience in comparison the preceding table may be 

 condensed to present the average germ content observed in the case 

 of each of the cows during the three different conditions of barn 

 management. This condensed summary of averages is given in 

 Table VIII. 



Table VIII. — Average Germ Content of Milk under Varying Barn Conditions. 



This table brings out the fact that the individuality of the cow 

 stands out rather sharply in connection with barn studies of this 

 class. The germ content as observed with Millie F. is high through- 

 out these test§. It is also interesting that the counts from Millie 

 F. B. B., her daughter, are consistently low through all of the tests. 



Since on each night the first three cows were successively milked 

 into a single pail and the last three into a second pail there is some 

 evidence regarding the effect of this practice upon the germ content 

 of the milk. The evidence in the present instance is exactly con- 

 tradictory, since with the first pail there is a steady decrease in the 

 germ content of the succeeding messes of milk while with the second 

 pail the increase is almost as constant.
