fifth and sixth streams, but these also contained many more 
bacteria than were found in the ninth and tenth streams. 
After that point the germ content did not seem to decrease 
materially. These experiments would indicate that in order to 
exclude the fore-milk containing a high germ content it is nec- 
essary to discard at least six good sized streams from each 
quarter of the udder. It is obvious that this means a consid- 
erable quantity of milk and would mean quite an appreciable 
financial loss in a herd of much size. 
GERM CONTENT OF MILK AFFECTED BY FORE-MILK. 
While the number of bacteria in the first few streams of milk 
is normally considerably higher than is contained by the main 
part of the milk, the writer was of the opinion that when this 
surplus of organisms found in the fore-milk is mixed with the 
entire milk of the cow the total increase in bacteria would not 
be very great. To determine this point the following series of 
experiments was made. | 
Method of experiment.—In the main the details of these ex- 
periments were similar to those which have already been de- 
scribed. At each milking the first three streams from each 
quarter of the udder were drawn from five cows and the re- 
mainder of the milk drawn in the usual way. Another group 
of five cows was milked without rejecting the fore-milk. Sam- 
ples of the mixed milk of each of these groups of five cows 
were taken for the determination of the bacteria content. The 
treatment given the two groups of cows was alternated from
