Papers and Notes on the Genesis and Matrix of the Diamond Diamonds

Abstract

AMONG the subjects which attracted the attention of the able and versatile geologist of Philadelphia—whose early death was so deeply mourned both in this country and the United States—was that of the mode of occurrence and the origin of the diamond. At the meeting of the British Association at Birmingham in 1886, Prof. Carvill Lewis read a short paper “On a Diamond-bearing Peridotite and on the History of the Diamond”; and in the following year he communicated to the Association meeting at Manchester a much longer and more elaborate paper on the same subject, which was entitled “The Matrix of the Diamond.” It was well known to Carvill Lewis's numerous scientific friends in this country that he had collected much valuable evidence concerning the association of diamonds with peridotite and serpentine in all parts of the world, and had arrived at certain very definite views concerning the constant association of the crystalline form of carbon with the ultrabasic rocks.
