Mr. Paine wrote to Dr. Voelcker on the 12th of April : — 
" I have some linsecd-cakc which was sent to mc for the best linseed-cake; 
I am very tloubtlul as to the purity of it." 
The following was the composition of the cake : — 
Moisture 11*85 
Oil 8-50 
*Albumiiious compounds 28 '25 
Mucilage, starch, and digestible fibre .. .. 27 'SO 
Woody fibre (cellulose) 14-96 
fMineral matter (ash) 8-85 
100-00 
* Containing nitrogen 4 -30 
t Coutuiuiug sand 3-01 
The results of the examination showed that the cake contained 
earth-nut husks, in addition to crushed linseed ; that it was poor 
in oil, and contained more sand than first-class linseed-cake, 
and consequently was neither a pure nor a best linseed-cake ; 
and they point to the policy and economy of buyers purchasing 
only what is guaranteed as pure. 
Mr. Paine subsequently wrote : — 
" I have often complained to the maker whether the cake was the best or 
not, and he has always assured me that it was. Since the analysis I have 
written to the makers and informed them of the result of it ; they deny that 
it could harm cattle." 
2. Mr. Charles Middleton, Holkham, Wells, Norfolk, wrote 
to Dr. Voelcker on the 14th March : — 
" Dear Sir, — Will you kindly send me an analysis of cake sent per rail, 
at your earliest convenience ; you will please let me know if it is a pure 
cake, as it is marked ' pure,' and could you tell me the value for feeding ? — 
Yours truly, 
" Chas. Middleton, 
" Dr. Voelcker." 
The analysis of the cake gave the following results : — 
Moisture 11-80 
Oil 9-30 
* Albuminous compounds 21-62 
Mucilage, starch, and digestible fibre .. .. 35-65 
Woody fibre (cellulose) 12-93 
-f Mineral matter (ash) 8 • 70 
100-00 
* Containing nitrogen 3-46 
t Containing sand 4-25 
The cake, which was branded " pure," was poor in oil and 
albuminous compounds, and contained 4^ per cent, of sand.
