" Re Milk Sample, No. 53.
Vestry Hall, Piccadilly,
November 13 th, 1897.
Dear Sir,
In your certificate to the Magistrate of the Marlboro'
Police Court, upon the above sample, you certified that the
milk contained 10.87 per cent, of milk-solids, and you gave
the conclusion that the milk contained "not less than three
per cent. of added water."
In my analysis, made on September 25th, the result was
milk-solids 10.94 percent., and, having judged the milk to be
watered, I gave the odd fraction in favour of the vendor, and
based my certificate upon the milk-solids certainly not exceeding
11 per cent.
Taking good average milk as containing 12.5 per cent. of
milk-solids, it follows that 11/12.5 = .88, and this gives
88 per cent. of average milk, plus 12 per cent. of added
water.
I shall be much obliged if you will favour me with
A description of the methods used in your analysis,
The standards of reference used,
And the methods of calculation,
as the case has been adjourned for the purpose of further
consideration.
Faithfully yours,
(Signed) JAMES EDMUNDS.

Dear Sir,
Milk Reference No 53.
Our method of analysis was the ordinary "maceration
process " which is so well known to milk analysts.
The results you obtained agreed with ours, so there is no
necessity to go further into methods of analysis, but we
may confine ourselves to the conclusions drawn from these
results.
