Acalcium-magnesium carbonate that crystallizes in the hexagonal system. It is white to reddish or greenish-wliite and sometimes of darker shades, even reaching brown and black in some varieties, with a vitreous and sometimes pearly lustre. Dolomite, both as a mineral and as a "rock, is found in various parts of Europe. In the United States it occurs at many localities in Vermont. Khode Island. New Jersey, New York, and .Missouri. It is found both crystal- lized and massive. The crystallized varieties in- clude the pearl spnr. which is so called from its lustre. The massive varieties are frequently colored; the variety containing iron is called broicii upar: the varieties containing manganese and cobalt are reddish. The compact varieties are used as building-stones. The Houses of Parliament in London were built from a variety found at Bolsover :Moor, and Saint Patrick's Cathedral, in New York City, is built from a variety found in Westchester County, N. Y.

DOLPHIN (OF. ilalphiii, daulphiii, Lat. del- phiiius, from Gk. ii<pls, tlclphis, dolphin). A cetacean of the family Dclphinida-, ehaiaclerizcd by the moderate relaiive size of the head, differ- ing in this from the cachalots, and also usually b/ having numerous simply conical or nearly conical teeth in both jaws, although some of the species lose those of the ujiper jaw at an early age. The blow-hole is single. The family Del- phinidLe includes, along with the dolphins, black- lish, porpoises, grampuses, etc., many animals which on account of their larger size arc com- monly called 'whales,' as the beluga, etc. The names 'dolphin' and 'porpoise' are often used interchangeably, but the true dolphins have the snout prolt)ngc"d into a rather slender l)eak. which is abruptly separated from the convex forehead, even by a" marked furrow; both jaws are fur- nished "with numerous equal teeth. The species are numerous, and none apparently has a very wide geographical range. They are voracious animals, and arc said to prey not only on fishes, medus*. cephaloiiods. etc., but even on the wounded and feeble of their own species. They live in herds, which often delight the voyager in the ocean solitude by their gambols. Gather- ing about a ship, they display their agility in a thousand graceful motions, now lea])ing with curved bodies many feet into the air, then dart- ing through a wave with incredible velocity, leav- ing a slender wake of whitening foam under the water; now the thin back-fin only is exposed, cutting the surface like a knife; then the broad and muscular tail is elevated as the animal plunges perpendicularly into the depths. Th^e common dolphin (Dclphinus ilclphis) is found in the Mediterranean and in the northern tlantie Ocean. It is usually not more than or 8 feet long, but individuals have been seen of 10 feet. The body tapers toward the tail, which is erescent-slia"pcd, and about a foot in breadth. The beak is about inches long, and the blow-hole crescent-shaped. The color is blackish on the back, grayish on the sides and satiny white. The female dolphin brings forth a single young one at a lime, which she suckles and nurses with great care. Tlie flesh of the dolphin was formerly considered a delicacy, and sailors still regard the .■apture of one as a hiippv event, giving a beef like alternative to their fare of salted meat. From the form of its beak, the dolphin receives from the French the names of hcc d'oie (goose- beak) and oiV dc mcr (sea-goose). It was very different Iv regarded and designated by the an- cient Greeks, to whom it was hicros ichthiis (sacred fish), and was invested with many fabulous attributes, and was the subject of many mvtholoi;ieal legends. It was supposed to be peculiarly friendly to men, perhaps iM-enuso
