"J. AtrGTJSTUs Voelcker." 
Mr. Mannington wrote on September 12 : — 
" Sir, — In reply to yours at band. On inquiry, it was found there were a 
few mustard-seed cakes put in the linseed-cakes by mistake. — Yours truly, 
"J. A. Voelcker, Esq." "IsAAC Mannington." 
Dr. Voelcker was not able to obtain further particulars, nor 
a reply to his inquiry as to how many cakes were linseed and 
how many mustard, though he pointed out how serious the mis- 
take might have been had the cakes been used.

" This is a cake showing a very high degree of adulteration, and possess- 
ing a bitter taste. " J. Augustus Voelceee." 
This was taken from a lot of four tons, forming the first por- 
tion of a contract for twenty tons, which had been guaranteed 
as pin'e and to contain 12 per cent, of oil. It was invoiced as 
pure, the vendor being Mr. Frederick Elgar, of Eochester, and 
the makers, the Oil Seed Crushing Company, Dover. The price 
of it was 71. 10s. a ton delivered. This cake contained a quan- 
tity of rape, also mustard and other foreign seeds. Ultimately 
2GI. was paid for the four tons.
