for pure cake not to let the opportunity slip. A whole cake 
sent proved to be as bad as the original sample. Further 
letters were received from Mr. Maddison on February 10th and 
February 19th : — 
" Foxberry, Albro', Darlington, February 10th, 1885. 
" To J. A. Voelckcr, Esq. 
" Dear Sik, — I am still in communication with Messrs. J. Hindhaugh and 
Co., respecting the linseed-cake ; they refuse to give me the name of the 
maker, saying he is not the responsible party. I had a letter from them 
asking me to name a reasonable sum that I would take for the cake being 
deficient ; I oifered to take two tons of good cotton-cake. In reply to it they 
say the maker requests me to send the whole of the cake on hand back, so 
that they may have it fairly examined. I have written to them to-day 
declining to send all the cake back, as I had already sent them two whole 
cakes to show them, and if I could not get the little 1 had asked for I would 
have to try what the law would do for me in the matter. — 1 am. Sir, yours 
truly, J. Maddison." 
" Foxberry, Albro', Darlington, February lOtli, 1885. 
« To J. A. Voelcker, Esq. 
" Dear Sib, — I had a letter yesterday from Messrs. J. Hindhaugh and Co. 
to say they had a letter from .John EUershaw and Sons, the makers of the 
cake I complained of, and they say they have had the cake I sent to them 
analysed by you, and that it has been returned as pure, and that the deprecia- 
tion arises through the cake being kept too long. Is that so ? — Yours truly, 
" J. Maddison." 
Dr. Voelcker replied on February 20th that the keeping of 
the cake for a long time would not put into it any impurities 
which did not originally exist in it. 
2. Mr. Joseph Martin, of Highfield House, Littleport, Ely, 
sent, on February 7th, a samplvj of cotton-cake and one of 
linseed-cake. Dr. Voelcker reported as follows : — 
CoTTOx AND Linseed-cakes. 
" Joseph Martin, Esq. February 11th, 1885. 
" Dear Sir, — The cotton-cake is pure and of fair quality. The linseed- 
cake is one of the hardest pressed I have seen, and, besides being so extremely 
poor in oil, is also low in albuminous compounds, and contains a large 
quantity of starchy impurities. — Yours faithfully, 
" J. Augustus Voelckek."
