This is an adulterated meal, containing admixture of starchy material, 
and it has, besides, 7^ per cent, of sand. Linseed-meal ought to contain 
from 30 to 35 per cent, of oil ; this sample has only 8| per cent. 
Mr. Knight fortunately had the analysis made before purchasing 
any of the meal. 
4 . Mr. J. B. Ball, of High OSley Manor, Newport, Salop, for- 
warded on January 7, 1892, a sample of linseed-cake which he 
said had been guaranteed to him as “pure” and “to contain 12 to 
13 per cent, of oil.” Mr. Ball complained that his cattle did not eat 
it well, and that it was very gritty and bitter. 
Dr. Voelcker reported on the cake as follows : —

This cake is a grossly adulterated one. In it I find quantities of rape 
and cockle seed ; also seeds of spurrey, mustard, polygonum, hemp, Camelina 
sativa, &c. It has also over 3 per cent, of sand. 
The cake was invoiced as “ Linseed-cake,” and two tons were 
purchased in October 1891, at 91. 5s. per ton, carriage paid, for 
delivery in November. 
In reply to Mr. Ball’s complaint about the cake the vendors 
wrote : — 
Dear Sir, — Yours to hand. We did not sell you E. K. linseed-cake. 
We sold you a 12-per-cent, cake made for us * * *, and it is a very good 
cake and good value. I shall see you on Monday at Newport. — Y’ours 
truly, 
November 27, 1891. 
The vendors ultimately allowed Mr. Ball 15 s. per ton. 
5. Mr. C. Neale, of Kneeton, Nottingham, sent on January 7, 
1892, a sample of linseed-cake for an opinion as to purity. Upon
