Qtuwterly Reports of the Chemical Committee, 1888. 379 
10. Mr. Sheffield Neave, of Mill Green Park, Ingatestone, 
sent, in May 1888, a sample of maize-meal which was reported 
by Dr. Voelcker to be an adulterated sample and not genuine 
maize-meaL It contained a considerable admixture of oat- 
husk, oatmeal, and other materials. This was bought from a 
corn-dealer on the London market, who explained that their 
clerk had, owing to his ignorance in these matters, bought it 
from another firm, who invoiced it to them as "feeding meal." 
SI. 18s. per ton was paid, instead of 5^. 7s. 6d., the original 
price. 
The following cases referring to Liibseed-calces will show the 
necessity of insisting upon a guai'antee of purity being given, 
and that the purchaser should not be satisfied with anything 
short of it or recommendations of other than " guaranteed 
pure " cakes : — 
11. Mr. W. Hollins, jun., Pleasley Vale, Mansfield, sent, in 
August 1888, a linseed-cake which was reported on as being 
" a very impure and mouldy cake." This was a cake of Messrs. 
Willows, Holt & Willows' manufacture, and sold by a firm in 
Leeds. Mr. Hollins, in a letter dated September 13, 1888, 
stated that this firm " do not of course call it a pure cake, but at 
the same time they recommend it to me in preference to a 95 per 
cent, pure cake, as they say it is better worth the money. They 
offer me the cake at 61. 12s. 6d. in Leeds, less IJ per cent, 
discount for cash ; also a 95 per cent, pure cake at 71. 15s. in 
Leeds ; but they say they consider the cheaper cake better value 
for the money." 
12. Mr. J. G. Beevor, of Barnby Moor, Retford, sent, in 
August 1888, two samples of linseed-cake which Dr. Voelcker 
informed him were very impure, and advised him to have nothing 
to do with them. They contained cockle, rape, hemp, spurry, 
niger, polygonum, and other seeds in quantity. Mr. Beevor 
informed Dr. Voelcker that they were offered to him, not as 
pure, but as being strongly recommended. The purchase was in 
consequence not made. 
13. Captain Stanley, of Longstowe Hall, Cambridge, sent, 
in May 1 888, a linseed-cake, which turned out to be impure ; 
it was bought by the bailiff", and though it was supposed to be 
of the best quality, costing 11. los. a ton, there was no written 
guarantee of purity.
