I reported to the Committee in September, 1937, that I considered
that the number of Corporation Houses should be increased
by one hundred and fifty, and this report was accepted and it is
upon this basis that the present housing plans are being drawn up.
INSPECTION AND SUPERVISION OF FOODS
MILK.
Milk was again subjected to bacteriological supervision. The
results were very good although the counts were not quite so
satisfactory as in the previous year. Over 90 per cent of the samples
of ordinary milk purchased in the winter months complied with the
standard for Pasteurised milk, and 63 per cent of the summer
samples reached this standard.
Bacillus coli was found to be present in many of the specimens
examined. In the summer months it was present in 68 per cent of
the samples of milk purchased, but in the winter months it was
present in only 20 per cent of the samples.
Two specimens of Pasteurised Milk had a very high count;
the firms responsible were warned and the later samples complied
with the standard.
One sample of Accredited Milk did not comply with the
requirements.

The following table shows the results that were obtained during the year:—
