ts. — Brande. Austrian. A rose-cut diamond of 139 1/2 carats. Sir Isaac Newton suggested that the diamond is combustible, but the first to establish the fact were the Florentine Academicians, in 1694; they succeeded in burning it in the focus of a large lens. Lavoisier, in 1772, examined the results of combustion, which showed it to be pure crystalline form of carbon. The uses of the diamond include the following:— Abradant for various purposes, in wheels, laps, and slicers. Stone drilling and sawing. See carbon Toolpoints. Engraver's ruling, and marking graduations on instruments. Glass-cutting.Lenses.Jewelry. Di′a-mond-cut′ter's Com′pass. （Diamond-cutting.) An instrument used to measure the inclination of the sides of jewels. It is a movable arm a, inserted at an angle of 45° into a metallic base b. It is shown in the lower illustration of Fig. 1630 as measuring the inclination of the collct-side to the girdle and the bizet to the table. See

A toy on the principle of the thanmatrope, the stroboscope, and phenakistoscope, which depend for their action upon the persistence of visual impressions. Upon different parts of a card are detached parts of a given figure, and when the card is rotated these become assembled and give a combined impression to the eye. En-rock′ment.
