The mean composition of the genuine samples of milk, as shown by the following table, is rather inferior in quality as compared with four previous years:
| Sp. Gr. | Milk-fat. | Solids (not fat). | Total Solids. | |
|---|---|---|---|---|
| 1915 | 1032.0 | 3.72 | 8.82 | 12.54 |
| 1916 | 1031.0 | 3.63 | 8.57 | 12.20 |
| 1917 | 1032.0 | 3.70 | 8.80 | 12.50 |
| 1918 | 1030.2 | 3.75 | 8.75 | 12.50 |
| 1919 | 1031.5 | 3.66 | 8.74 | 12.40 |
Butter.—One hundred and twenty-seven samples of butter were examined;
all contained boric acid, from 7 to 26 grains per lb. One sample was adulterated,
containing 80 per cent, fat other than that of butter fat.
Margarine.—The 77 samples of margarine, all genuine, contained boric acid
up to 27 grains per lb.
Cream.—Two samples of cream only were analysed; they were both genuine.
One of these, properly labelled, contained a small quantity of boric acid.
Coffee.—Twenty-one samples of coffee were analysed; one, a test coffee,
contained 50 per cent, of chicory.
Miscellaneous Samples.—The remainder of the samples were of a miscellaneous
character and are enumerated in the table—they require no special comment.

BACTERIOLOGICAL EXAMINATION OF MILK.
During the year 5 samples of milk were submitted to the Council's Bacteriologist
(Dr. Foulerton) for examination.
Of these 4 were found to be "good."
All the reports were submitted to the Public Health Committee and a warning
was only necessary in one case where a relatively small quantity of foreign dirt was
reported, sufficient to suggest carelessness in handling the milk.
