Of these all the vinegars contained sulphuric acid, though not in a
larger quantity than is allowed by law, viz., 1 part in 1,000. All
the cocoas were genuine. Of the eight breads 7 contained no alum,
the eighth contained a small quantity. Of the milks twenty-two
were pure, and six were adulterated with water. The coffee contained
a small quantity of chicory. Of the peppers all were genuine.
Of the mustards three were mixed with flour, and coloured with
turmeric. Of the arrowroots two consisted entirely of potato
starch. Both the flours were genuine.
I have the honour,
Gentlemen,
To remain,
Your obedient Servant,
GEORGE ARTHUR ROGERS,
