Chemische Krystallographie

Abstract

WITH this, the second, volume, Prof, von Groth completes that half of his great work which deals with inorganic salts. The fact that it has appeared within two years of the publication of the first volume is, even when every allowance is made for the assistance which we believe has been placed at his disposal, eloquent testimony to the remarkable industry displayed by the author. To absorb, digest, and arrange in orderly sequence such a mass of data is a gigantic task, and such rapid progress demands unremitting labour and indomitable perseverance. To the great services rendered by Prof. Groth to mineralogy and crystallography, and to those preeminent qualifications which mark him out as the obvious man to plan and carry through this important work, Dr. Tutton, in writing of the opening volume (NATURE, 1907, vol. Ixxv., p. 529), has referred in graceful and felicitous language. The present writer, who was privileged to serve his novitiate in mineralogical science in Prof. Groth's laboratory at Munich, feels it would be presumption on his part to add anything to those words beyond his cordial agreement with them.
