Extract

Up to the present time only one of the several ehildrenite occurrences known has been examined both chemically and crystallographieally. This is the well-known occurrence at the George and Charlotte mine near Tavistock, from which nearly all the specimens seen in collections were obtained. The crystals often attain a dimension of 1 cm., so that material for analysis can be easily obtained free from gangue. Crystals from this locality were analysed by Rammelsberg, Church, and Penfield, and it is on the results obtained by the last-named that the comparatively simple formula for this mineral is based.
