The rate of the flow Of milk through
the machine was / 800 pounds per
hour, and the time the milk was sub
jected to heat Ii to SO seconds. From
"a results of tests made under both win
II ter and summer conditions it is con-
sidered that the number of bacteria
capable of resisting the heating pro-
cess is subject to wide fluctuations.
Il Tt should be understood that the
pasteurized milk, thus tested, is milk

germs remaining in the farmers re

made to determine what per cent Of
