In 43 cases the total number of organisms was below 100,000 per 1 Cc,
and in 26 cases it was below 10,000 per 1 Cc. In 3 cases less than 1,000
were present.
The chemical composition of these samples was as follows:—
Fats varied from 2.8 to 4.7 per cent., with an average of 3.57 per cent.
Total solids varied from 11.8 to 13.9 per cent., with an average
of 12.44 per cent.
Three samples contained less than 3 per cent. of fat.
Twelve samples contained less than 12 per cent. of total solids.
There was practically no difference between the average chemical
composition of Grade "A" (Tuberculin Tested) milks and that of the
general supply.
One sample of Certified Milk was examined. This was satisfactory.
Amongst the other samples examined were:—
