Ton per cent, of the samples contained 4 per cent. or more fat. Milk with
this fat content does not appear to be uncommon.
In 12 cases where the fat content subsequently proved to be four per cent.,
from observations made at the time of purchasing, the samples showed that in
6 instances the milk was stirred with a hand measure before serving. In one ease
the milk was served from the hand can of a roundsman and was probably well
mixed. In one case the sample was from a newly filled counter pan. In four
cases served from counter pans the agent could not say whether or not the milk
was stirred or plunged before sale. It is probable that even distribution of milk
fat is not secured by casual mixing with hand measures; the use of efficient
plungers would secure this end. On the other hand, where there is reason to
believe milk is properly plunged, a.n analysis has shown the presence of over
four per cent. of fat.
Of the 12 samples referred to above eleven were purchased at dairies or» milk
shops, and one from a street vendor.
