DETAILS OF NON-GENUINE SAMPLES TAKEN

Sample No.	Article	Nature of Adulteration or Deficiency	Action Taken
81	Boracic Ointment	Contained 1.55% of boric acid instead of the 1.0% (limits 0.9 to 1.1) of the British Pharmacopoeia.	Vendor warned.
118	Cheese, processed	Consisted of processed cheese of the Gruyere variety and contained only 40.3% of fat, calculated on the dry matter.	Vendor warned.
134	Custard Powder	Contained a small piece of string and several hard granular or seed-like lumps. (The small lumps present were not of foreign material, but had apparently been formed by the wetting and subsequent drying of the powder with drops of water.)	This article was from a School Feeding Centre—stock was withdrawn.
135	Gravy Powder	Contained 6% of rust (iron oxide). Rust present was in the form of small flakes and would appear to have been derived from the rusty surface of a metal container.	Manufacturer informed—subsequent sample proved genuine.
112	Milk	Contained only 3.95% of butterfat instead of not less than 4%. (Channel Island Milk should show on analysis a butterfat content of not less than 4% (The Milk (Control and Maximum Prices) (Great Britain) Order, 1947.)	Dairyman interviewed and warned regarding proper mixing of milk.
161	Milk	1% deficient in milk solids other than milk fat.	Freezing test did not indicate added water. Dairyman informed.
