The cake was poor in oil, and had been made from anything 
but clean linseed, for it was contaminated with buck-wheat, 
broken corn, and small weed-seeds. In this and the two follow- 
ing cases no further information could be obtained in answer to 
the usual inquiries respecting the sellers of the cakes, &c. 
2. Mr. E. C. Clarke, Manor Farm, Haddenham, Thame, 
Oxon, sent a sample of linseed-cake for an opinion as to its 
genuineness. The examination showed that it was not a genuine 
linseed-cake, but an adulterated or inferior compound linseed- 
cake, containing amongst other ingredients, in addition to 
linseed, cotton-cake and locust bean-meal. 
3. A sample of oil-cake was sent by Mr. Josh. Mackinder, 
Peterborough, who specially requested me to test it for the pre- 
sence of rape or other seeds. 
The cake, which was branded Pure, had the following

This cake was made from dirty linseed, containing, in addition 
to nearly 3 per cent, of sand, rape, wild mustard, polygonum, 
and numerous other small weed-seeds, which usually occur in 
badly screened linseed. Moreover, it was an old stale cake, 
slightly mouldy at the edges, and had a disagreeable rancid 
smell like old oil paint, and certainly was not a cake which 
should have been sold as pure linseed-cake and branded 
Pure. 
4. In the last Quarterly Report reference was made to a 
sample of linseed-cake, sent by Mr. Lister, U])per Morton
