146 Quarterly Report oj the Chemical Committee, March, 1893 . 
mere taut I bought it off is not the manufacturer ; and, as I do a deal of busi- 
ness with him in other things, I do not wish to give his name. He allowed 
me 31 . on the 4-ton lot. — I remain, yours truly, 
John Hy. Bletcheb.

Not at all a pure cake — but adulterated with rape-seed, mustard-seed, 
and cockle-seed, as well as some cotton- husk. 
Mr. Bletcher declined to give any information with regard to 
this case also. 
The following cases are given as examples of the desirability 
of obtaining a definite guarantee as to the purity of feeding 
materials, and as instances of what a purchaser may be supplied 
with if he neglect to provide himself with such guarantee. 
8. Mr. G. I. Stokes, of Bushbury Hall, Wolverhampton, sent 
on November 11a sample of Oil-cake which he said he was about 
to purchase as “pure.” 
The following report was given him : — 
November 19, 1892.

This is not pure. Besides a small excess of sand, it contains considerable 
admixture of rape. 
On receiving this report Mr. Stokes decided not to purchase.
