Mustard —Three informal samples containing a proportion of
wheaten flour varying from 8 per cent to 11.8 per cent.
Milk.
Of the 738 samples of milk (all but one of which were formal
samples) submitted during the year, 7 (formal) or 0.9 per cent,
were reported as adulterated, 2 of these samples being deficient in
milk fat and 5 containing extraneous water. The percentages of
extraneous water found in the 5 adulterated samples did not exceed
6 per cent., whilst the deficiency in milk fat in the 2 samples so
reported against was 3 and 6 per cent, respectively.
In the 5 years 1931.35, and in 1936, the percentage of adulterated
(formal) samples of milk was as under:—

A considerable proportion of the milk supply of London is
received at Clapham Junction and South Lambeth Goods Stations
and samples are systematically taken on the arrival of the milk at
these two stations. Such samples are included in the return on
page 102.
The adulteration of milk during the year under review (the
Analyst points out) remains under 1 per cent., and in all cases the
departure from the standard was slight. It must not be overlooked,
however, that the Sale of Milk Regulations, 1901, notoriously
require a low standard both in respect of milk-fat and solids-not-fat,
and it is to be hoped that the time is rapidly approaching when all
milk offered for sale to the public will at least comply with these
minimum requirements.
The average composition of the 730 samples of milk reported as
genuine, proved to be as under :—
Total milk solids 12.49 per cent.
Milk fat 3.65
Non-fatty solids 8.84 „
