366 Quarterly Reports of the Chemical Committee, 1884. 
on their own behalf, which confirmed Dr. Voelcker, allowed a 
deduction of the whole amount charged for the potash from the 
bill. Mr. Ashdown subsequently wrote : — 
" As I have always found the vendors very straightforward, and their 
articles almost always up to their guarantee, if the Chemical Committee 
think well to publish what happened with regard to the sulphate of potash, 
1 think no benefit can be derived by publishing their names." 
This case shows how desirable it is that purchasers should 
have an analysis of sulphate of potash, or kainit, and how 
necessary it is that agents for merchants and manufacturers 
should themselves take care to have an analysis of the cake or 
manure which they offer to the consumer.

" The cotton-cake is a very inferior whole-seed cotton-cake ; it is very poor 
in oil and albuminous compounds, and contains an excess of woody fibre in 
the shape of cotton-seed husks and cotton wool. I should not like to feed 
stock with such a cake. — (For Augustus Voelcker) 
" John Augustus Voelcker." 
The cake was stamped " W.G. Pure," 2 tons, at 6/. 5s. per 
ton, having been bought from Messrs, Hy. Leake and Son, King's 
Lynn. Mr. English wrote subsequently : — " I have spoken to 
Messrs. Leake, finding fault with this parcel, having had much 
better for nearly a year past from them." 
4. Mr. Henry Mellish, of Hodsock Priory, Worksop, sent, on 
November 26th, 1884, a sample of linseed-cake and one of 
decorticated cotton-cake. 
The report and analysis were as follows : — 
"November 29th, 1884. 
"Dear Sir, — The linseed-cake is an impure cake, containing a considerable 
quantity of foreign seeds, &c. It is also of low quality. Was it sold to you 
as pure? The decorticated cotton-cake is pure, but contains some hard 
lumps, and requires to be finely ground before using it. — Yours faithfully (for 
Augustus Voelcker), 
" JouN Augustus Voelcker."
