Tuberculin Tested Milk. Seven samples were examined all of which satisfied the methylene
blue and coliform tests.
Tuberculin Tested Milk (Pasteurised). The three samples taken were reported to contain
respectively 1,980, 3,430 and 20 bacteria per millilitre—legal maximum 30,000 per millilitre.
Pasteurised Milk. A maximum of 100,000 bacteria per millilitre is prescribed for milk sold
under this designation and 85 of the 95 samples examined during 1937 were reported as satisfactory,
the average count for these being 26,288 bacteria per millilitre. Two samples gave counts slightly
in excess of the legal standard, viz. : 115,000 and 141,000 bacteria per millilitre. Two others taken
from the same vendor were reported to contain respectively " probably more than 2,000,000 " and
1,036,000 bacteria per millilitre. In connection with these latter samples, I arranged for further
tests to be carried out by three different bacteriologists and for this purpose the contents of one
half-pint bottle of milk were divided into three parts under sterile conditions and sent to the three
laboratories together with three unopened half-pint bottles of milk from the same delivery.

I communicated with the wholesalers who supplied the milk to the Fulham retailer and had
an interview with the Chief Chemist to the Company, who gave an explanation of the temporary
difficulties which accounted for the bad results. Several samples have since been purchased from
this Company and satisfactory reports received.
