In addition to the above-mentioned commodities 44 informal
samples of milk were examined at the office for fat content.
I would like to comment briefly on the samples found to be
unsatisfactory.
Ammoniated Tincture of Quinine
Two samples of this drug were found to be deficient in ammonia
to the extent of 27 % and 49 % respectively. In each case it was found
that the solution had been stored in the shop for a long period, in
in the second instance for over ten years, and a letter was sent to all
retail chemists in the district pointing out the importance and necessity
for the periodical examination of their stocks of those drugs
which might deteriorate on being stored for long periods.
Ice Lollies
A sample of a raspberry flavoured Ice Lolly, manufactured in
the district, was found to contain lead to the extent of 3.5 parts
per million. An orange flavoured lolly taken from the same shop
contained only .85 parts of lead per million.
The lead content of lollies should not exceed 1 part per million
and in view of the fact that the vendor was selling these lollies at
1d. each and did a considerable trade among children, particularly
due to the very warm weather enjoyed during last summer, it was
suggested to him that he should obtain new moulds of plastic or
other suitable material, to which suggestion he willingly agreed.
The difference in the lead content of the two samples was due either

the time the lollies were kept in the moulds.

An informal sample of a proprietary Lemon Drink was submitted
for analysis and found to be in an active state of fermentation and
