‎---- EDITION ORIGINALE DE CET OUVRAGE INCONNU DE DSB et de PARTINGTON dans lequel Berthier a réuni et publié en un volume les mémoires et articles qu'il avait fait paraître de 1827 à 1832 dans différentes revues ---- "Berthier was called in 1806 to the newly completed central laboratory of the Board of Mines. In 1816, he was appointed professor of assaying and chief of the laboratory at the Ecoles des Mines. Berthier pblished more than 150 papers on a wide variety of scientific subjects. Most appeared in Annales de chimie and Annales des mines. He analyzed kaolin, pioneered in locating deposits of native phosphates for use in agriculture, analyzed dozens of minerals an metalliferous ores and discovered several new mineral species. He is credited with knowing, before Mitscherlich's work on isomorphism, that substances that are chemically different may have the same crystalline form and may even cocrystallize... His importance lies in what he added to French geology, mineralogy and metallurgy...". (DSB II P. 72) - Partington IV pp. 97/98**505/A7DE‎
