CONSTITUENTS OF THE CARROT.These are crystallizable and uncrystallizable sugar, a little starch, extractive, gluten, albumen, volatile oil, vegetable jelly, or pectin, saline matter, malic acid, and a peculiar crystallizable ruby-red neuter principle, without odour or taste, called carotin.

Starch, gum, albumen, resin, lignin, extractive, and organic acids exist in tobacco, as they do, in varying proportions, in other plants.

Dr. John gives the following as the composition of the pulp surrounding the seeds: Coloring resinous matter, 28; vegetable gluten, 26.5; ligneous fiber, 20; coloring, 20; extractive matter, 4; and a trace of spicy and acid matter.

This was found to be so, but it was accompanied by such a mass of extractive as made it in the long run more troublesome, and hence it was abandoned.

The ash was found in the usual way, and the extractive by the difference.

These results in reference to extractive, etc., reveal nothing that has not been known before.

Wynter Blyth, who gives the only analyses of annatto I have been able to find, states that the composition of a fair commercial sample (which I take to mean the raw article) examined by him was as follows: water, 24.2; resin, 28.8; ash, 22.5; and extractive, 24.5; and that of an adulterated (which I take to mean a manufactured) article, water, 13.4; resin, 11.0; ash (iron, silica, chalk, alumina, and common salt), 48.3; and extractive.

"Agriculture," we have observed, is a great complex of industries, in which many different products are taken from the first simplest extractive stage, and then put through successive processes to make them more nearly fitted for their final uses.
