![test by your Inspector, 99 were of fanners’ milk and 8 of retailers’ milk. Of the farmers’ milk 14 samples were found to be below the standard. These 14 samples came from seven different farmers, and from enquiries made the causes of deficiency were as follows:—• At three farms the milk had not been mixed, so that the milk in each churn varied in quality. If mixed together the milk would have been above the standard in each churn. At the other four farms the periods between milkings were too irregular, only the morning’s milk being deficient in cream. At only one farm were suspicions aroused that the milk was being tampered with. This farmer’s milk does not now come into the Borough. The three samples of milk taken from a retailer were testeil to find whether the deficiency of fat in a sample which had been analysed and found of very poor quality was due to the cream rising to top of churn during process of delivery. The sample taken from top of churn was found to contain 4'3 per cent, milk-fat, while that drawn from the tap at bottom of churn contained 3‘3 per cent, milk-fat. SELF-RAISING FLOUR. Five of the 20 samples of self-raising flour analysed were reported to contain from 0'4() per cent, up to 0-70 per cent. Sulphate of Calcium due to the use of impure superphosphates to render the flour self-raising. A special investigation was made by the Public Analyst of several samples of such impure super- phosphates and of bread baked from flour in which they were used as baking powder. The Analyst reported the results of his investigations show,— “that by tbe process of baking a certain ])roportion, varying from 30 to (>() per cent, of the sulphate of calcium becomes converted into sodium sulphate and calcium carbonate, but that in no case was the whole of the calcium sulphate so converted, the average amount changed being about 50 per cent.”](https://iiif.wellcomecollection.org/image/b28942802_0083.jp2/full/800%2C/0/default.jpg)
