190 Annval Report of the Consulting Chemist. 
11/. a ton. The lowest-priced cake is introduced into this 
circular in the following terms : " A parcel of linseed-cakes 
made entirely of fine Bombay linseed, kiln-dried, and branded 
' pure,' we can do at 9Z. Is. 6(1." 
Leaving this exceptional, and, as it appears to me, very ques- 
tionable, kiln-dried pure linseed-cake out of consideration, as also 
pure Marseilles cake quoted at 9Z. 17s. Qd., there is a difference 
of 32s. tid. per ton between the lowest priced and the highest 
quotation of a number of Hull-made, professedly pure linseed- 
cakes, which appears to support the opinion I have just ex- 
pressed, namely, that linseed-cakes are sold as " pure " at the 
present time, which, although not purposely adulterated, ought 
not to be branded " pure " and sold as such. 
Compound linseed-cakes, or professedly mixed cakes, not un- 
frequently are branded " best ; " and consumers of cake, tempted 
by the difference of some 15s. or 20s. between the price of such 
best cake and pure linseed-cake, and believing that they are 
buying pure linseed-cake, are too apt to be led astray, and, 
on the strength of the " best brand," are liable to pay 20s. or 
80s. more than such cakes are really worth. 
I have considered it my duty to refer to these matters, because 
I know that mal-practices of cake-crushers and dealers are 
again gradually extending all over England. I would there- 
fore urge upon the Members of the Society to put into practical 
operation the forms of guarantee recommended by the Chemical 
Committee to intended buyers of linseed-cakes. 
Decorticated cotton-cake from America I have never found 
adulterated. At the present price it is the cheapest article of 
food that can be used by feeders and fatteners of stock, who will 
do well to mix it with Indian-corn-meal in equal proportions 
when feeding cattle in winter, or in the proportion of one of 
cotton-cake and two of Indian corn during the warmer months 
of the year. 
A very useful grain to mix with decorticated cotton-cake, 
reduced to meal or finely broken up, is rice. The quality 
of rice-meal, I find, varies very much, as will be seen by the 
following analyses of three samples sent to me for examination 
lately by Members of the Society. 
The sample No. 1, it will be seen, contained much less oil 
and albuminous compounds, and more indigestible woody fibre 
than the two others. In No. 3, the proportion of oil was even 
greater than in the best oilcake, and this sample contained but 
little woody fibre. It is therefore, unquestionably, a valuable 
fattening meal. Although the meals No. 1 and No. 3 were sold 
at about the same price, the analyses of the two samples clearly 
prove the superior fattening value of No. 3 ; they also afford
