Analysts' Annual Report. 99
The lead detected in two of the samples finds its way into
the Lemonade from the use of a syphon consisting of or containing
this metal, the use of which, unlined, points to a distinct
potential danger and should, if possible, be stopped.
Eleven of the 12 informal samples of Lemonade Powder
had been compounded with Tartaric Acid, an acid foreign to the
Lemon and, in our opinion no article can be properly described
as "Lemonade" which had been manufactured with any acid
other than Citric, which acid is considerably more costly than
Tartaric.
A large number of the samples of Apples examined was
found to have Arsenic on the surface, but in most cases the amount
present did not exceed 1-100 grain per lb., and if these samples
were not included amongst those returned as adulterated the
percentage of adulteration for the year under review would be
reduced from 6 to 4.3 in the case of formal samples; from 4.7
to 4.0 in the case of informal samples; and from 5.3 to 4.15 in
the case of all samples submitted.
It will be seen that some 70 varieties of Foods and Drugs
were submitted and examined during the year and we think
your Council is to be congratulated on the purity of these, as
shown by the results of our analyses ; serious instances of adulteration
occurring very rarely in the Borough.
We are, Mr. Mayor and Gentlemen,
Your obedient Servants,
