Qnarterly Reiwrts of the Chemical Committee, 1889. 783 
" Mr. Gibbons also wished me to say that in case you lay the matter 
before the Council that you will give him a chance to defend himself there. 
" All I wish now to know is : lias there been anytliing added to de- 
teriorate the quality of the bones, or other than was absolutely requisite to 
use in their manufacture. — Awaiting your reply, I remain very truly yours, 
" Dr. J. A. Voelcker." " W. H. Webb."

"Dear Sie, — I thank you for your lettei-, which now gives authorita- 
tively the information as to who the manufacturers were, and that the 
manure supplied to you came direct from their works. 
" In answer to your question, I beg to say, firstly, tliat I did find in the 
sample you sent me of what was supplied to you as pure dissolved bones, 
material which was not dissolved bones and constitutes an admixture detri- 
mental to the character of pure dissolved bones; secondly, my enquiries 
were addressed to you not on the ground of the money-value of the manure, 
but on the ground of its not being what it was represented to be. At the 
same time I have no hesitation in saying that, by the admixture, the manure 
was made to appear, according to the analysis, to have a value which it 
Avould not practically have had to the farmer purchasing it, to the same ex- 
tent as if it had been derived entirely from bones and acid. 
" Mr. Gibbous's statement as to there being no such thing as Pure Dis- 
solved Bones is quite incorrect, and it has been clearly laid down and agreed 
by manure manufacturers, since the passing of the Merchandise Marks Act, 
that Pure Dissolved Pones should consist of bones and acid only, without 
any admixture. — Yours faithfully, " J. Augustus Voelceek."

" A grossly impure cake. It is full of seeds other than linseed, and has 
over 5 per cent, of sand. A very bad cake indeed. 
" J. Augustus Voelckee." 
Of this cake 4 tons had been purchased, at 61. 17s. 6d. a ton, 
at Hull, from Messrs. W. 11. Cross & Co., High Street, Hull, the 
manufacturers.
