nutriment, and pleasantly flavored, is no doubt a compound which might
be used with advantage; but it should be sold at a moderate and fair
price.

[Footnote 30: Cellulose is the term applied to the chemical substance
which forms woody fibre. The latter is made up of very minute
spindle-shaped tubes. In young and succulent plants these tubes are
often lined with layers of soft cellulose. In many plants--such as
trees--in a certain stage of development, the substance lining the cells
is very hard, and is termed _lignin_, or _sclerogen_. This substance is
merely a modification of cellulose; and both resemble in composition
sugar and starch so closely that, by heating them with sulphuric acid,
they may be converted into sugar.]

[Footnote 31: One part of oil is equal to 2-1/2 parts of starch--that is,
2-1/2 parts of starch are expended in the production of
1 part of fat.]

[Footnote 32: No difference is here assumed between the nutritive value
of sugar and starch.]

plant may be preserved in good condition up to June. I have advocated
the cultivation of the radish as a food crop in the "Agricultural
Review" for 1861.]

[Footnote 34: According to some chemists, sugar does not exist in ripe
grain, but is produced in it, during the process of analysis, by the
action of the re-agents employed and the influence of the air.]
