Quarterly Reports of the Chemical Committee, 1888. 357 
In reply to further inquiries, Mr. Skinner wrote on 
December 8 : — 
" Dear Sir, — I first bought the cake and booked it at 6/. 16s. Sd. free 
to my station, a pure 98 per cent, seed-cake, to contain not less than 10 per 
cent, of oil ; but when asked to sign the agreement in my pocket-book in the 
market, the agent for manufacturer backed out, and said he would sell the 
cake and guarantee it as good as the sample (the one I sent you first). 1 
agreed to take it if the sample analysed satisfactorily.— I am, yours faith- 
fully, "Alfred C. Skinner." 
" Dr. J. A. Voelcker." 
The manufacturers allowed 16s. 3d. per ton on the 10 tons, 
but Mr. Skinner would not mention the names of the parties. 
This case shows the necessity of sending to be analysed a 
cake from the bulk delivered, and not trusting merely to a 
sample ; also tlie necessity of having a written guarantee.

'* J. Augustus Voelcker." 
Five tons of this cake had been purchased at 61. 15s. a ton 
from an agent of the manufacturers in Hull, the vendor's invoice 
describing it as " Linseed-Cake," and the printed heading of the 
invoice stating " Best Pure Linseed and Cotton Cakes." The 
cake was branded " Pure." Mr. Wood said : — 
" It was sold to me as pure ; I particularly expressed that at the time 1 
bought the cake, and have a witness to that effect." 
On Mr. Wood complaining, he was asked to send a whole 
cake to the makers, they returning a certificate, of which the 
following is a copy : —
