Kunz later proposed that this mineral be named Moissanite, in honor of its discoverer. The complete mineralogical composition of the meteorite as given by these various writers, including Mr. Tassin, is, then, as follows: Nickel iron: (1) Kamacite. (2) Plessite. (3) Taenite. Phosphide of iron: (1) Schreibersite. (2) Rhabdite. (3) A black phosphide, unidentified. Carbide of iron: (1) Cohenite., (2) Graphitic iron (?) Sulphide of iron: (1) Troilite. Chloride of iron: (1) Lawrencite. Silicide of carbon: (1) Moissanite (Moissan). Carbon: (1) Diamonds, colorless, yellow and black. (2) Cliftonite. (3) Amorphous. (4) Graphite. Silicon (Tassin). Platinum (Mallett). Copper (Derby). Olivine (very rare) (Tassin). Chromite (Tassin). Fayalite (?) (Tassin). Daubreelite (Foote and Derby). Of the several partial and complete analyses of the iron that have been published, the following are selected, No. I being by Moissan, No. 2 by Booth, Garrett, and Blair, and Nos. 3 and 4 by Wirt Tassin, No. 4 being that of a shale-ball iron next to be described: VI. The Iron Shale And Shale Balls Occurrence, Composition, and Origin.--Scattered over the surface of the plain, and practically coextensive with the iron, are abundant fragments and nodules of brown iron oxide, sometimes stained greenish from the presence of a nickel hydroxide. These, as a rule, have a somewhat shaly or platy structure, t...
