Dr. J. A. Voelcker. May 12, 1892. 
De.\e Sie, — I have filled in the particulars as far as I can, I don’t care 
to disclose the name of vendor as he is a good customer for barley, and I 
have done a good deal of business with him, and have had no fault to find 
up to now.— Yours faithfully, Jno. J. Rodenhuest. 
3 . A London firm of land agents sent on April 26, 1892, on 
behalf of one of their clieirts, a sample of^ linseed -cake which the 
latter had ordered from a local dealer. A verbal order had been 
given for “ linseed-cake.” Upon the agents paying a visit to the 
estate, their attention was directed to the cake, and they forwarded 
a sample to Dp. Voelcker for analysis. The following report was

Grossly impure, being full of rape aud other foreign seeds, and with 4 
per cent, of sand. 
On further inquiry, it was found that the cake, though charged 
at 9(. a ton, was simply invoiced as “ Oil-cake.” 
The above case shows how necessary it is not only to stipulate 
for linseed-cdJie being supplied, but also to see that there is a written 
guarantee to that effect, and that the cake is described on the invoice 
as linseed-cake, and not merely as oiV-cake,
