Since 1st October, 1934, the milk supplied to necessitous children at schools
has been obtained through the Milk Marketing Board's scheme and not through the
Council's contracts, but head teachers were advised to obtain pasteurised milk only
under this scheme. The Council's medical officer of health approves the source of
supply and quality after consultation with the medical officers of health of the
Borough Councils concerned, who take the necessary samples for examination.
In all the cases of unsatisfactory supplies by contractors the attention of the
chief officer of supplies was called to the matter, and in the more serious cases the
medical officer of health of the district was also informed.
The arrangement made for the co-operation of the medical officers of health in
regard to the examinations of milk supplied to Council's institutions and schools
in the county and in certain areas outside the county has been continued during
the year with very satisfactory results.
Under this scheme reports have been received on the chemical examination of
535 samples from hospitals and 447 from schools, of which 14 were deficient in fat
(10 from hospitals and 4 from schools).
In addition to the above, results have been received of the bacteriological
examination of 200 samples of pasteurised milk supplied to hospitals of which 17
failed to comply with the standard laid down in the Milk (Special Designation)
Order, 1923, and of 255 samples of milk supplied to schools, 34 failed to comply
with the adopted standard or, in the case of pasteurised milk, with the standard
for that grade.
Of the 864 samples of drugs and medical supplies examined during the year, Drugs.
80 (or 9-3 per cent.) were found to be either definitely unsatisfactory for use or
below standard strength or quality.
Satisfactory 784

Deficient in active constituent 29

The percentage of samples reported upon adversely during the previous year
was 7.6, and the results for 1934, therefore, show an appreciable increase, thus
emphasising the need for regular examination in order that supplies of drugs shall
be kept strictly up to the required standard. Samples of two consignments of
creosote capsules were rejected as having a content of one minim instead of two
minims, and two samples of quinine hydrochloride tablets were found to be one
