Hericart de Thury (1776-1854) and Houry (1780-1843) were both French mining engineers. Within this work they outline a new systematic method of describing minerals. Based on twenty-two characteristics; the method relies on such features as hardness, color, crystal structure, chemical characteristics, and electrical and magnetic properties. The work took a very practical approach to mineral identification in order to make it a more useful tool for the mining industry. The tables use this system to describe over 200 minerals.
