Linseed Meal. 
When crushed linseed is treated with bi-sulphide of carbon, 
a good solvent of oils, it can be deprived more perfectly of it.s 
oil than by pressure. Linseed-meal, exhausted of most of the 
oil contained in linseed, of late has become an article of com- 
merce, which appears to be imported into England principally 
from America. 
Two samples of such linseed-meal on analysis showed the 
following composition : 
No. I. No. 2. 
Moisture 10-15 .... 11-15 
Oil 2-80 .. .. 2-15 
*Albuminoiis compounds .. .. 29-25 .... 30-75 
Mucilase, sucar and digestiLlo fibre 39-67 .... 38-43 
Woody fibre (cellulose) .. .. 11-83 .... 11-07 
Mineral matter (ash) 6-30 .... G-45 
100-00 100-00 
* Containing nitrogen .. .. i'OS .... 4*92 
From a practical or economical point of view, oil is the most 
valuable constituent of oil-cakes, and as first-class linseed-cakes 
contain from lOJ to 12 per cent, of oil, whereas linseed-meal, 
treated with bi-sulphide of carbon, usually contains under 
3 per cent., such meal is not worth as much as good pure linseed- 
cake. 
The samples of meal examined by me during the year were all 
made from clean linseed ; and as the price of the meal is from 30s^. 
to 21. lower per ton than linseed-cake, and the meal is very handy 
for mixing with other food, or for the making of linseed mucilage, 
it is well worth the attention of rearers and fatteners of stock. 
Chinese Pea-cake. 
The following is the composition of a sample of Chinese pea- 
cake lately examined by me : 
Moisture 12-79 
Oil 7-15 
*Albuminous compounds 39-25 
Starch, sugar, and digestible tibre 29-60 
Woody fibre (cellulose) 5*67 
Mineral matter (ash) 5-54 
100-00 
Containing nitrogen G"28 
This cake, which I believe is made from a species of Dolichos 
bean (^S(ja Idspidd) cultivated in China and Japan, it will be 
seen by the preceding analysis is very rich in nitrogenous con- 
stituents. It contains a good deal of starch, and about 7 per cent.
