three of mincemeat were examined and in no case were
preservatives, colouring matter, or metallic contamination
detected.
Condiments, Spices, Ac.
Of five samples of mustard, six of pepper and two of
vinegar, one of the mustards was reported inferior on account
of its containing traces,—not exceeding 1 per cent.—of starch
coloured with turmeric.
The vinegars were free from arsenic and mineral acids.
Spirits.
Eleven samples of whisky were analysed and of these three
were reported inferior on account of their containing the
minimum of proof spirit and two were adulterated. The
latter were respectively 35'7 and 36 degrees under proof.
Drugs.
The total number of drugs analysed during the year was
forty-six and of these four were found not to comply with the
requirements of the British Pharmacopoeia. Two specimens
of strong tincture of iodine were found to contain an excess
of iodine—11*8 grammes and 10'5 grammes of iodine respectively
per 100 millilitres, the amount required by the Pharmacopoeia
being 10 grammes.
This year we had another instance of milk of sulphur adulterated
with calcium sulphate to the extent of 44 4 per cent.
The sample referred to was taken informally and when a
formal sample was purchased by the Inspector the correct
article was supplied.
A sample of zinc ointment was deficient in zinc oxide. It
contained only 13'5 per cent, instead of the 15 per cent,
required by the Pharmacopoeia.

The following miscellaneous samples proved to be genuine:—

Arrowroot1 sample.
Baking powder1 „
Chocolate4 samples.
Lemon squash2 „
Olive oil5 „
Sugar, Demerara2 „

Tests for arsenic, lead and copper in the baking powder
gave negative results and the specimens of lemon squash
proved to be free from preservatives and metallic contamination.
