Kunz. George F. Kunz, at the tenth annual reception of the New York Microscopical Society, exhibited a microscopical specimen of a meteoric stone, in which, some foreign experts claim, diamond exist. The stone fell at Novy Urej, Krasnoslobdsk, Government of Penza, Russia, on September 4, 1886, shortly after seven o'clock in the morning, and was found by MM. Latshinof and Jeroleief, who, after examining it, came to the conclusion that it was filled with meteoric diamonds. Mr. Kunz, in speaking of the specimen, said that it was of special interest, since Fletcher had given the name "Cliftonite" to the new cubic form of carbon, which he obtained from the meteoric iron that was found in the sub-district of Yunadegin, Austrialia, in 1884, and suggested, since this form is peculiar to the diamond and not to graphite, that, although the crystalization may have been initially favorable to the formation of the diamond, yet it was so rapid that the graphite form only was developed. He had only received two grams of the meteor found by MM. Latschinof and Jeroleief, and in view of the fact that the stone weighed four pounds, or nearly two thousand grams, it was very difficult to judge from his specimen of the nature of its bearings. Mr. Kunz made a careful examination of the two gram specimen, but found absolutely no trace of diamonds. There occurred in the stone small grains of olivine or peridot, which being rounded and having a marking as well as a luster, must have been mistaken for diamonds. The discovers, according to Mr. Kunz idea, head probably described the olivine as diamonds without a thorough examination, although he could not alleged positively until he had seen both the meteor and the papers describing the discovery, neither of which had yet come to this country. Mr. Kunz also exhibited a specimen of porphyritic volcanic peridotite, the altered carbonaceous breccia of which has yield nearly seven tons of diamonds, valued, uncut, at $250,000,000; a section of a rock containing a beautiful two karet absolutely white perfect octahedron, and several specimens of rocks showing all the characteristic minerals which were obtained during a trip through the country last summer. - Jeweler's Weekly.
