'•A cake made from damaged seed, and not as well screened as it 
should be. " J. Atjgtjstus Voklckek." 
Mr. Egar wrote on February 1, 1889, stating as follows the 
result of his complaining to the vendor : — 
"Replying to yours of January 15. On my complaint the vendor 
stated he found on inquiry the screen was neglected by the attendant. Not 
properlj' cleaned for some (days?) just at the time they were making my 
cakes, for which he proposed to make an allowance. We settled the 
matter after I had reminded him it was unfortunate the screen got out of 
order on two occasions when my cakes were being made, the deliveries being 
October and December." 
The matter was finally settled with Mr. Gray by a payment 
of 601. for 85 tons delivered to date, being a deduction of 31. 15s. 
on the purchase. 
5. Mr. W. H. Wykes, of Weston Park, Shipston-on-Stour 
(agent for the Countess of Camperdown), sent on December 7, 
1888, a sample of linseed-cake, to obtain an opinion as to its 
purity. Five tons of this had been purchased on November 24, 
at 8/. 10s. a ton, delivered to station from Hull. 
After examination Dr. Voelcker gave his opinion that the 
cake was " a decidedly impure one." 
Mr. Wykes then explained (December 10) that he had not 
in the present instance obtained any guarantee of purity from 
the manufacturers, " having hitherto been satisfied with their 
cake, which had always been sold to him as a pure cake." At 
his request a full analysis was then made, with the following 
result : — 
"December 18, 1888.

" The cake contains, as you see, over 4 per cent, of sand ; it has besides 
much admixture of starchy substances and foreign seeds, and is an impure 
cake. " J. AtJGtrsTtrs Voelckee." 
On Mr. Wykes's complaining, the manufacturers wrote to 
him as follows : — 
" To W. AVykes, Esq. " Hull : January 5, 1888. 
"Dear Sik, — Yoiu- letter to Mr. re last lot of linseed-cakes 
arrived in my absence on journey. I am sorry you ai-e so much dissatisfied 
with it. I pay very little attention to Voelcker's analyses ; they are not a
