In the case of sample C 65 which contained 4.2 per cent. of added water
and in which the presence of added water was confirmed by determining
the freezing point of the sample, the defending solicitor stated that the
sample had been analysed and found to be genuine. He therefore requested
that the "third part" should be sent to the Government Chemist for analysis
(the cost of an analysis is £2 2s. 0d.). At the second hearing of the case
the defence pleaded guilty as the certificate of the Government Chemist stated
that the sample contained not less than 5.0 per cent. of water. It was,
however, argued that milk satisfying Government requirements with regard
to composition contains 3.0 per cent. of fat and 88.5 per cent. of water
whereas this sample contained 3.56 per cent. of fat and 88.3 per cent. of
water. This is true but the amount of added water is of course obtained
from the deficiency of solids-not-fat.
The vendors of samples C 84, C 85 and C 86 were represented by one
solicitor, the wholesaler agreeing to pay any fines or costs. Each vendor
pleaded guilty and was fined £5 and £1 1s. 0d. costs. One vendor was not
satisfied and asked that the case should be reheard. This was allowed and
a further solicitor engaged to defend. As a result the conviction was quashed
in his case but he was required to pay £5 5s. 0d. costs.
The average composition of samples of milk analysed during each month
of the year is shown below. Adulterated samples and cowshed samples
are included; "appeal to cow" samples and reconstituted milk samples are
not included.
