FROM an itinerant dealer, who collects minerals at the Lead Hills in Scotland, I lately procured a variety of the phosphate of lead, which, I suspect, is not described in any of our mineralogical arrangements or scientific journals. The ore in question is of a bright orange colour, and consists of groups of simple six-sided prismatic crystals, from an eighth to a quarter of an inch in length, filling cavities in pale yellow crystalline phosphate of lead.
