After fusion with nitre yields with water a yellow solution, which aft'ords the reaction of chrome. Soluble in bisulphate of potash. E44, where E is Fe, Mg, Cr and 44 is Qr, A1 and perhaps 4?e. Analyses of chromite a from Eoraas by v. Kobell, from Baltimore I crystallized, c massive by Abich, d from the gold mines of Beresowsk by Moberg, e from Bolton in Canada, f from Memphramagog in Canada, both by T. S. Hunt:— Oxide of chrome . Alumina . . . Protoxide of chrome Protoxide of iron . Magnesia . . . Silica .... In imbedded crystals and grains, in granular masses, usually disseminated, in alluvium. Is found in nodules in serpentine near Q-assin in the depart ment of Var in France; in irregular veins on the Gulsen near Kraubat in Stiria; in limestone near Portsoy in Banfshire, and Buchanan in Stirlingshire; in large quantities in serpentine on the islands of Unst and Fetlar ; in Silesia at Grochau, Silber- berg, Hartenberg; in Moravia at Hrubschiitz in considerable quantities; in Bohemia at Eonsberg and Altsmoliwetz dissemi nated in serpentine; in Norway near Eoraas; in Siberia at Katharinenburg in large masses, and in several other places disseminated in serpentine, and in small grains and octahedrons in the gold and platinum stream works; in Maryland, Penn sylvania, Vermont, Massachusetts, in serpentine and in lime stone at Hoboken in New Jersey, and massive and crystallized in limestone on the Bare Hills near Baltimore; as sand in the Isle a Vaches near St. Domingo in the West Indies. 139.
