Abstract
A shipment of specimens recently received at the National Museum from Mr. H. G. Clinton of Manhattan, Nevada, contained a mineral labeled “yellow turquoise” which appeared unusual in character and, since a large number of aluminium phosphates are under examination in this laboratory, it was subjected to an analysis. The results of this investigation, as presented below, identify the mineral as barrandite, a hydrated phosphate of iron, probably the ferric iron analogue of variscite and which has, hitherto, been known only from the original locality which is Przibram, Bohemia. The locality is Manhattan and the label gives the additional information that the mineral occurs “in lime-rhyolite contact with vashegyite and utahlite.”
