"The name calamine (G.rman, _G.lmei_), from _lapis calaminaris_, a Latin corruption of cadmia ([G.eek: kadmia]), the old name for zinc ores in general (G. Agricola in 1546 derived it from the Latin _calamus_, a reed), was early used indiscriminately for the carbonate and the hydrous silicate of zinc, and even now both species are included by miners under the same term."
