An impure cake, 'containing a quantity of rape-seed, as also spurrey, 
cockle, and other weed seeds, and with rather more sand than a pure cake 
should have. 
A ton of this cake had been purchased as “ pure linseed-cake,” 
and cost 9?. 17s. 6cf. per ton at Tuxford station, G.N.R. The 
vendor was Mr. John Martin, of Tuxford, Newark, agent for Messrs. 
Pearson Brothers, Gainsborough, Lincolnshire. Every cake was 
branded “ Pearsons’ 95% Pure.” 
When Mr. Neale told the vendor that the cake was not pure, he 
replied that it ought to be, for it was bought and sold as “ pure 
linseed-cake.” 
6. Mr. E. R. Pratt, of Ryston Hall, Downham, Norfolk, for- 
warded on January 23, 1892, a sample of linseed-cake for an opinion 
as to its purity. 
It had been purchased as “ Bsst Pure Linseed-cake (95 per 
cent.),” at 9^. 7s. 6d. per ton, delivered. 
The cake being, in Dr. Voelcker’s opinion, impure, ]\Ir. Pratt 
wished the full analysis to be made, and the following wa^ the 
result ; — 
Moisture 
Oil 
* Albuminous compounds (flesh-forming matters) 
Mucilage, sugar, and digestible fibre

The cake is neither best quality nor pure. It contains a good deal of 
foreign seeds, principally spurrey and rape, with starchy matter. 
An allowance of 15s. per ton was made by the vendor, whose 
name, however, was not forthcoming. 
7. Mr. Jas. A. Gordon, of Arabella, Nigg station, Ross-shire, 
N.B., sent on January 23, 1892, a sample of linseed-cake for 
analysis. Twenty tons had been purchased on a guarantee that the 
pake should contain 10 to 11 per cent, of oil, and 32 to 35 per cent.
