Abstract
The occurrence in Bolivia of minerals containing the rare element germanium has been recently noted by Prof. S. L. Penfield. One of these minerals from Potosi, described bv him in 1893, has the chemical composition of the Freiberg argyrodite (the original source of germanium), but was determined to be cubic, and not monosymmetrie, the system to which argyrodite was originally referred. To the supposed new mineral the name eanfieldite was given, but when Weisbach's reexamination showed that the Freiberg argyrodite was possibly ctlbie, the name was transferred by Penfield to another mineral containing germanium, which he described in 1894.Keywords
