([27]) This gentleman has invented an exceedingly simple but effective furze-bruiser, which I hope soon to see in general use.

([29]) 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.

([30]) One part of oil is equal to 2½ parts of starch—that is, 2½ parts of starch are expended in the production of 1 part of fat.

([31]) No difference is here assumed between the nutritive value of sugar and starch.
