If the average bacterial counts in the experiment are compared 
with those in Table 2, a similar experiment, it will be seen that the 
average count from the small-top pail was 24,489 in one series 
and 17,027 in the other. The open pail showed a greater variation, 
being 86,212 in one case and 22,677 in the other. In the last series 
with the open pail (Table 6) there are a few high counts which
