Quarterly Report of the Chemical Committee, March, 1890. 195 
In enclosing the above correspondence, Mi-. Stirton wrote : — 
" I am perfectly satisfied with their letter, and as they are willing 
to meet me I think, perhaps, it may be rather hard upon them to 
publish the error on their part." 
In answer to Mr. Stirton 's letter, Mr. Voelcker replied : — 
" I can only say that the makers should have taken the proper 
precaution of screening the seed before crushing it." 
4. Mr. J. Giles, of Bradford House, Kidderminster, sent a 
sample of cake on January 27, 1890 for analysis. Mr. Giles 
described the sample as " Oilcake " at 71. lbs. per ton, delivered. 
In reply to inquiries, he said : — 
" I certainly purchased it as a pure linseed-cake of the second 
quality. By this I mean a cake not containing the greatest amount 
of oil." 
The cake was invoiced, " Linseed Cake." Five tons were 
purchased. 
The following analysis was forwarded on February 11, 1890 :— 
Moisture 13*43 j 
Oil . . 639 
A lburninous compounds (flesh-foiming matters') . 23'44 1 
Mucilage, sugar, and digestible fibre . . .32 72 
Woody fibre (cellulose) 13"39 
Mineral matter (ash) 10 63'' 
1 Containing nitrogen . . . 3-"5 
* Including sand .... 5 - 19 
A grossly impure cake. 
The cake, it will be noticed, contains only a little more than 6 
per cent, of oil, an excessively large amount of woody fibre, and 
over 5 per cent, of sand. It contained a large quantity of starchy 
impurities, and was very low in nitrogen. Amongst the impurities 
of the cake, rape, hemp, and earth-nut figured prominently. 
Mr. Giles received the following letter from the vendor : — 
John Giles, Esq., Bradford House. January 31, 1890. 
Deab Sir,— The — Linseed-cakes are not a pure cake, but are made 
from the linseed as imported. The price of the — Linseed-cake, guaran- 
teed 95 per cent, purity, is 9/. 10s. per ton, delivered at . Yours truly 
5. Mr. G. Taylor, agent for the Earl of Dudley, sent on 
February 7, 1890, from the Estates Office, Dudley, two samples of 
decorticated cotton-cake for analysis, stating that he had purchased 
the cakes as pure at the price of bl. 17s. 6c/. a ton (in Liverpool) for 
6 tons. The analyses, sent on February 13, 1890, were as below ;
