49&#93; ANE this species are employed by fo- reign dyers for green colours of various shades. From die expressed juice of the leaves, a green ink may be prepared ; and if die florets only be used, it will be of a lighter shade, but from the whole flower, the co- lour will be much deeper. Relying on the authority of Dambournev, we shall add, that animal wool pre- viously immersed in a solution of bismuth, acquires a pleasing light vigogne colour. 3. Anemone nemoroscr, L. or the Wood- Anemone ; anodier wild sort, bearing only one white, or some- times purplish, flower on a plant. — SeeCunTis's Flor. Land. ii. 38. In medicine, this plant may be usefully employed as a substitute for cantkarides, or Spanish flies 3 for it produces not only a more speedy, but less painful, effect. Its juice is so extremely acrid, that it has been justly suspected to occasion the dy- sentery among cattle, and inflam- mation, accompanied with a dis- charge of bloody urine, in sheep. Hence the necessity of guarding these animals against the cause of distempers, which are frequently so formidable in their consequences, as to deprive the unwary husband- man of a great portion of his most valuable live-stock. 4. Anemone ranunculoides, L. or the Yellow Wood- Anemone, which grows wild near King's Langley, Herts, and Wrotham, in Kent. It generally produces, in April, two flowers on one stalk, with rounder leaves than the preceding species. See p. 5. Gerard's Herbal, 3S3. 1. On account of its corrosive acri- mony, the juice of this vegetable is also used by the inhabitants of Kamtschatka, for a similar delete- rious purpose as is mentioned of the .second species. mo. 1. — vol.

See p. 4. Curt. Flor. Lond. Its medicinal uses are, though in an inferior degree, similar to those before described. ANEMOSCOPE, a mechanical instrument for determining the course and velocity of the wind. That part which exhibits the former, or shews from what point of the compass the wind blows, consists of an index, moving round an up- right circular plate, like the dial of a clock ; on which, instead of the hours, the thirty-two points of the compass are represented. The in- dex which points to the divisions on the dial, is turned by a horizontal axis, having a trundle-head at its outward extremity. This trundle- head is moved by a cog-wheel, on a perpendicular axis ; at the top of which is fixed a vane, moving with the course of the wind, and impart- ing motion to the whole machine. The contrivance is extremely sim- ple, and requires in its construc- tion only, that the number of cogs in the wheel, and rounds in the trundle-head, be equal ; because, when the vane moves entirely round, the index of the dial should also make a complete revolution. An anemoscope of this construc- tion is placed in one of the turrets of Buckingham-house, the resi- dence of Her present Majesty. The anemoscope invented by Mr. Pickering, and published in the Philosophical Transactions, No. 473, is a machine four feet and a quarter high, consisting of abroad and weighty pedestal, a pillar at- tached to it, and an iron axis, about £ half
