QUARTERLY REPORT OF THE CHEMICAL 
COMMITTEE, 
December, 1891. 
1. Mr. R. H. Newill sent on October 15, on behalf of the Earl of 
Powis, Walcot, Lydbury North, Shropshire, a sample of linseed-cake, 
two-and-a-half tons of which had been purchased fi'om Messrs. 
Marston Bros., Bull Ring, Ludlow, agents for the manufacturers, 
Messrs. Earles and King, Liverpool. The cake was invoiced as 
" E. & K. Linseed cake," and each piece was branded with the name 
of the makers ; the price was 9/. lO*-. per ton delivered. 
The following analysis and report was returned : — 
October 22, 1891. 
Moisture 
Oil 
^ Albuminous compounds (flesh-forming matters) 
Mucilage, sugar, and digestible fibre 
Woody fibre (cellulose) 
^ Mineral matter (asli) 
' Containing nitrogen .... 
• Including sand ..... 
This uake is impure, containing, as it does, nearly 6 per cent, cif sand. 
Tlie price, 9/. 10s. per ton for a cake containing only 9i per cent, of oil- 
even supposing it to have been a pure one (which this is not)— is veiy high. 
On complaining to Messrs. Marston Bros., the latter forwarded a 
copy of a reply which they had received from Messrs. Earles^ and 
King, and which ran as follows : — 
A 17 and IS E-'^change Buildings, Liverpool: October 1891. 
DE.iR SiKS, — We are verj- sorry to hear of any complaint of our cake. 
The seed this season has been very poor, and it is impossible to screen it as 
wc should like. We beg to point out that we give no guarantee as to oil in 
our cake — to anyone who will imyfor it we will give as much ns they want ; 
but we at once admit 6 per cent, sand is too much, and we will make 
your friend lO.v. a ton allowance on tlie two tons. This pays him for the 
whole of the sand, and we will send you the money on hearing that our 
proposal is satisfactory. Please let us have a sample of the cake. 
Yours faithfully, 
Eaeliss & KiSG. 
Messrs. Marston Urothers, Ludlow. 
Mr. Newill accepted the allowance of 10s. a ton offered.

2. The following case illustrates well the difficulties which 
may arise wlien linseed-cake, guaranteed as "pure," is made, 
not by the vendors themselves, but for them under a contract
