Acer Majus: Acer montanum candidum C. B. Acer Pseudo-Platanus Linn. Great Maple, improperly called Sycamore: a large tree, with pentangular serrated leaves; producing small greenish flowers, and a fruit com-posed of two capsules, including each a whitish seed at the end where they are joined, and spreading at the opposite end into a membranous wing. It is a native of the mountains of Switzerland and Austria, and now common in England.

All the parts of the maple contain a sweet saccharine juice; which, exuding on the fur-face of the leaves, renders them subject to be preyed on by infects. The roots, trunk, or branches, wounded early in the spring, bleed a large quantity of clear liquor; which, in its dilute state, tastes somewhat sweetish; and being infpiffated, yields a brown coloured concrete sugar, with a syrupy matter resembling melaffes.

The juice, unboiled, has been drank as an antifcorbutic. The sugar and melasses, which are said to be less sweet than those extracted from the sugar cane, and their sweetness to be likewise somewhat different in kind (a), are supposed to be more medicinal in disorders of the bread. Considerable quantities of this sugar, made from a species of maple in Canada, are imported for that use into some parts of Europe, particularly France: the samples which I have seen of it are of a brown colour, and of a more grateful sweetness than the common brown sugars.
