No choice for President having been reached, the election was decided in the House of Rep- resentatives, but meanwhile Crawford had been stricken with paralysis, which precluded his effectual candidacy.

(1910) 9,371; (1920) lUjioy, CRAYON, a colored pencil consisting of a cylinder of fine pipe-clay colored with a pigment. Crayons are said to have been made in France in 1422. In lithography, a composition formed as a pencil, and used for drawing upon lithographic stones. CREAM, the most oily part of milk. It is specifically lighter than the other constituents, and therefore rises to the surface, whence it is generally skimmed to be used as an adjunct in making tea and coffee palatable, to be eaten with various fruits, or for other purposes. In chemistry, hydrogen potassium tar- tarate (KHC4H4O6), a salt obtained from the crude tartar, or argol, which is de- posited on the side of wine casks during the fermentation of grape juice. It is a gritty white powder which forms small rhombic prisms, is sparingly soluble in water, and insoluble in alcohol. Heated in a crucible it evolves inflammable gas and the odor of burned sugar, and leaves a black residue of charcoal and potas- sium carbonate. In small doses it is a refrigerant and diuretic ; in large doses a powerful hydragogue purgative. It is given, mixed with jalap, as a purgative in cases of dropsy, and is used as a drink in febrile affections.

His principal works are: "The Rise and Progress of the British Constitution," and "The Fifteen Decisive Battles of the World." He died Jan. 27, 1878. CREATINE, methyl-glycocyamine. Methyl-guanido-acetic acid, CiHgNsOz + mo. or HN=Cj^((^jj )_(.jj^(.Q Qjj. Creatine is obtained from the muscular flesh of mammalia, birds, reptiles, and fishes. It has been found in the blood and urine, and brains of pigeons and dogs. It is obtained by chopping up the lean muscular flesh, removing the fat, and rubbing it with water and pressing it; the liquid is heated in a water-bath to coagulate the albumen, then strained; to the filtrate baryta-water is added, so long as it gives a precipitate, the filtrate con- centrated on a water-bath, the crystals, which separate, decolorized by animal charcoal and re-crystallized from water. Creatine crystallizes in rhombic needles containing one molecule of water, which is driven off at 100°. The water solution has a bitter taste, and is neutral to litmus. It gives a white precipitate with silver nitrate, which is soluble in potash. After a time the solution solidifies to a transparent gelatinous mass, which is re-
