Report of the Medical Officer of Health.
As regards the four informal samples of milk reported against
during the year, three were found to contain extraneous water,
whilst the remaining sample was deficient in milk fat.
Two of the informal samples of cream submitted were returned
as unsatisfactory. In the case of the fresh cream, the presence
of a boron preservative was detected, whilst the preserved cream
reported against was found to contain a slight excess of boric acid
beyond that declared upon the label: namely, 0.4 per cent.

The average monthly composition of all milks examined by me during the year and reported as genuine is shown below:—

For the whole year the average composition of all samples returned as genuine was:—

Total milk solids12.26%
Milk fat3.49%
Non-fatty solids8.77%

It may be noted that in the above table the total number of
genuine milks adds up to 737, whereas in the "Milk and cream"
table the number is given as 738. This discrepancy is accounted
for by the fact that one informal sample was submitted in a condition
that made it impossible to obtain reliable figures as to
