was found to be adulterated. This contained a preparation of
copper equivalent to 0.9 grains of crystallised sulphate of
copper per pound.
Salad and Olive Oils.— Of eleven specimens of olive oil,
two were found to contain forty and thirty per cent. of oil
other than olive oil, having the characters of arachis oil. Two
salad oils were returned as genuine.

salicylic acid to the amount of 3.5 grains per pint and was therefore
reported as adulterated.
Drugs. The total number of drugs analysed during the
year was thirty-two and only two of these were adulterated.
The latter were specimens of borax which were found to contain
ten parts of arsenious oxide per million. This is exactly
twice the limit of the British Pharmacopoeia.
In addition to the foregoing, the following samples on
analysis were found to be genuine:—
Coffee 4 samples.
„ Grape Nuts „ 1 sample.
„ Instant Postum „ 1 sample.
Lemonade Powder 3 samples.
Self-raising Flour 4 samples.
Treacle 1 sample.
The Public Health (Milk and Cream) Regulations.— Five
samples of cream and seven of preserved cream were examined
under these Regulations during the year. Adulteration was
reported in the case of a cream which contained 0.29 per cent.
of boric acid. All of the preserved creams contained boric
acid, but in no case was the limit of 0.4 per cent. exceeded.
The following Table shews action taken on adulterated
samples (other than milk and cream), and other infringements
of the Sale of Food and Drugs Acts.
