Of the 102 samples of milk, 48 were submitted to the phosphatase
test, 48 to the methylene-blue test, and 6 to the turbidity test.
These samples were reported satisfactory.

The 40 samples of ice-cream were examined at the Public Health
Laboratory.

Examination of Water from Swimming Baths
Thirty-two samples were submitted for examination. Satisfactory
results were obtained in 28 samples. In the remaining samples
there were slight deviations from normal, but subsequent tests
proved satisfactory in all cases.

The ten miscellaneous samples proved to be free of pathogenic
organisms.
