Not illustrated. 1915 Excerpt: ...and a residue consisting of graphite, a marooncolored variety of carbon, carbonado, and diamond was obtained. This residue was treated with aqua regia, hot sulphuric acid, hydrofluoric acid, potassium chlorate, and fuming nitric acid and the residues then left were treated with liquids of different densities to separate them. From a separation with bromoform, small fragments having the form, hardness, luster, and chemical composition of diamond were obtained. Pure, limpid diamonds in some cases were found which reached a diameter of 0.5 mm. Am. Jour. Sci., 1891, 3, 42, 415-417. fAm. Jour. Sci., 1893, 3, 470-473. jProci Am. Acad. Sci., 1894, 29, 204-211.

Analogous to this discovery it may be noted that microscopic diamonds were found in several hard steels by Rossel.f It may also be noted that the stone meteorites which contain diamonds have a composition similar to that of the peridotites in which the South African diamonds are found. Carbon in graphitic cubic form was noted by Haidinger and Partsch in the Magura meteoritej and regarded by them as a pseudomorph after pyrite, especially as planes believed to be those of the pentagonal dodecahedron were observed. Rose later suggested an origin of the cubes from diamond and showed by experiment that diamond heated out of contact with air becomes opaque and of graphitic appearance. The cubes from Magura were described more fully later by Brezin...
