21-2 Annual Report for 1907 of the Consulting Chemist. 
analysed in connection with the pi’izes awarded at the Society’s 
Show held at Lincoln in June, 1907. 
A. Feeding Stuffs. 
1. Linseed Cake. 
These, as noted, have been almost uniformly of good 
character. It has, indeed, but seldom happened, in the case, 
at least, of samples submitted to me, that cakes invoiced as 
“ Linseed cake ” have been found to be impure, and, speaking 
generally, no practical difficulty has been experienced in 
complying with the demands of the Fertilisers and Feeding 
Stuffs Act as regards the “limits” beyond which the com- 
position shall not vary. 
In one instance brought to my notice the purchaser had 
ordered “ Linseed cake ” and, on the invoice reaching him, it 
was noticed to describe the cake as “ Linseed cake ” but to have 
also the following qualifying note : — 
“ To comply with the Fertilisers and Feeding Stuffs Act, 1892, 
notice is hereby given that the Article or Articles invoiced above 
have been prepared from more than one substance or seed, and 
may be mixed or compounded with substances or seeds other 
than those implied by the name. The articles, however, are 
warranted to be of known quality or similar to sample shewn. 
“ Not responsible for weight, measure or quality after the delivery 
of the goods, or for the age, growth or sort of any seed.” 
The effect of such a note is to vitiate the guarantee conveyed 
in the use of the description “ Linseed cake,” for linseed cake 
must be made from one substance or seed only, viz.. Linseed, 
and may not be compounded with other substances or seeds. 
Purchasers receiving invoices thusmai’ked should return them, 
or the delivery, and insist upon having their goods properly 
described. 
2. Cotton Cake. 
The ordinary undecorticated cotton cake — made from 
Egyptian seed, as it is generally described — has been, as a rule, 
of good quality, and but few cases have occurred in which the 
seed has not been well cleaned or excess of sand been found. 
The use of borax as a preservative would appear also to 
have largely diminished. The unrestricted employment of a 
medicinal material of this kind is decidedly objectionable. 
Bombay cotton cakes, with the inducement of their lower 
price, have continued to be extensively used. But I am no 
more favourable than before to their employment, and seeing 
that neither cotton wool nor woody fibre can be called “ feeding 
materials,” any more than peat, I consider them, as a whole, 
to compare unfavourably with good Egyptian seed cake at 
the highei’ price asked for it. Of course Bombay cotton cakes
