Among condiments I may mention three
Ketchups. They present extraordinary variety. One
variety, No. 84, contains 22½ per cent. of salt; another,
No. 95, only 4 per cent. The first would greatly
promote thirst, but will keep; the second will not
keep when once opened, and was soon filled with
vibrios. From experience I should say that 10 per
cent. of salt is about the necessary quantity. All the
ketchups were free from animal matters and from
metallic contaminations.
As Lime Juice Cordials. are very much used,
it was thought advisable to submit the varieties to
analysis. Two of these have been examined and
found of the character indicated. From the name, it
must, however, not be inferred that they are cordials
by reason of their alcoholic contents. They are
wholesome and recommendable.
With the mention of three kinds of drugs,
Tartar Emetic (2), Epsom Salts, and Sulphate of
Quinine, I bring my Report to a close. The
Crystalline Tartar Emetic, No. 82, was perfect in
composition ; No. 88, which was in powder, was not
saturated as regards antimony. I may repeat reformer
experience that there is no certainty of obtaining
the genuine article unless well crystallized.
