chased, though their purity has not, as a rule, been so well main- 
tained as previously.

Most of these, though not all, have been American cakes, and 
their cheapness has no doubt attracted buyers ; but I cannot 
believe that cakes of such a hard-pressed nature, and having so 
little oil in them, are, even at low prices, to be compared with 
good cakes containing 10 or 11 per cent, of oil, or more, 
and which are so much softer and in better mechanical condi- 
tion for purposes of feeding. 
Of impurities in linseed-cakes the one most marked by its 
frequent recurrence is sand, I drew attention to this last year, 
but there is now still greater reason for fault-finding. The 
following analyses give evidence of the quantity of fine sand 
which is not unfrequently met with in linseed-cakes. Several of 
these cakes were sold under the name " pure," and were branded 
as such : —
