    Three of the above samples were of milk sold as Grade A and one of these was not satisfactory. The matter was taken up with the Licensing Authority of the producer’s area and the supply to Wakefield was discontinued. 4 other samples were sold in bottles labelled “ sterilised milk,” and whilst none of the milks were really sterile, 3 of them had very low bacterial counts (30*50 and 120 per c.c. and no coliform bacilli in 1/100th c.c.). The other sample so far from being sterilised had the highest bacterial account of all our samples, namely, 11644000 per c.c. Apart from these graded and ‘‘ sterilised ” milks, there was only one sample that came up to the bacterial standard of Grade A milk. 19 samples of milk were examined by animal inoculation for tuberculous infection and 2 of these (10*5 per cent.) were found to contain the infection as compared with 20 per cent, in 1925 and 30 per cent, in 1924, which indicates a progressive improvement. One sample was from milk produced in the City and one from outside the City. No definite evidence of Tuberculosis could be found on veterinary inspection of the cows in the sheds from which the milk was obtained, but there had been a change in animals in the period between sampling and inspection. Under the Tuberculosis Order the Veterinary Surgeon certified 5 cows in Wakefield cowsheds and these on slaughter were found to have generalised tuberculosis. Sediment in Milk. 27 samples of milk were tested for sediment by the City Analyst with the following results :—■ Parts per 100,000. Total Samples. Produced in City.
