1 44 Quarterly Report of the Chemical Committee, March, 1893 . 
This is a superior quality of oil-cake, rich in oil and other feeding com- 
pounds. (Signed) 
I have written to ask Messrs. Needham & Co. for the name of the 
manufacturer, hut I need hardly say I shall not think of having such 
rubbish as this cake appears to be. I find it true economy to buy a good 
cake. — Yours truly, W. Milltard. 
Dr. J. Augustus Voelcker. 
In reply Dr. Voelcker wrote : — 
J. W. Millyard, Esq. December 2, 1892. 
Dear Sir, — I thank you for your reply, and the present case affords you 
a good instance of what I have so often mentioned, namely, that it does not 
do to rely simply upon the figures of an analysis. In the present case, for 
instance, the oil is not composed merely of linseed-oil, but is made up also 
of the oils from the foreign seeds mixed with the linseed . . . Yours faithfully, 
J. Augustus Voelcker. * 
3 . Mr. R. Phipps, of Buckenhill, Bromyard, Worcester, sent on 
November 23, a sample of Lin seed- cake. 
10 cwt. had been purchased at 81. 10s. per ton, nett cash, from 
Messrs. Needham & Co., Worcester. The vendors stated it to be 
Linseed-cake, although the invoice subsequently received described 
it merely as oil-cake. 
Dr. Voelcker’s report was as follows : —

A grossly adulterated cake. It contains a lot of rape, cockle-seed, and 
earthnut, along with some half-dozen other kinds of weed-seeds which I 
have identified, and over 3 per cent, of sand. 
4 . Mr. Watson Peck, Jr., of Beckjay Farm, Aston-on-Clun, 
Salop, sent on Dec. 6, a sample of Linseed-cake which he stated had 
been guaranteed to be pure and to contain 12 per cent of oil.
