It will be seen that this cake is both deficient in oil and! 
albuminous compounds. It was adulterated with earth-nut-cake 
a/id buck-wheat, and probably not worth more than lOZ. per ton. 
No reply has been given to applications for the name of the 
vendor. 
A sample of oil-cake was sent by Mr. B. Smithin, Dumbleton, 
who wrote on the 25th July, 1872 : — " Dear Sir, — I send by this 
post a sample of oil-cake, which I wish you to analyse. I have 
been giving it to rearing calves and have lost five, and think 
there must be something wrong with the cake," 
The cake had the following composition : —

Dr. Voelcker reports that this was not a pure linseed-cake, 
although sold at 111. 10s., the price of pure cake, it being made 
from dirty linseed, containing a number of small weed-seeds that 
are usually present in unscreened linseed, and starchy matter, 
which does not occur in pure linseed-cake, but that he could not 
detect any poisonous ingredient in it. Dr. Voelcker has frequently 
pointed out the danger of using such cakes, but as this parcel 
was invoiced as oil- cake, and not as linseed-cake, the Com- 
mittee do not feel legally justified in publishing the names of 
the vendors.
