The experiments shown in Table 30 were made for the pur- 
pose. of comparing the relative decrease of the bacteria in 
samples of milk containing large and small numbers of bac- 
teria and to note the retarding effect of the lower temperature. 
The first three samples were obtained in the ordinary manner 
without special effort to exclude bacteria; the last. four were so 
taken that the external contamination was reduced quite mate- 
rially. Comparison of the first three with the last four ex- 
periments reveals the fact that samples containing the larger 
numbers of bacteria suffered a greater reduction in numibers. 
than did those samples containing the smaller numbers. This
