Antimony from Prussia. Mundick from Cornwal. A Marchasite very curiously variegated from Cole-Orton Coal-Pits in Leicestershire; all three from Dr. Woodward. A very fair and large Marchasite given me at Whitehaven in Cumberland, by the ingenious Will. Gilpin Esq;. An Orbicular Marchasite tuberated about the Bigness of a Hand-Ball. Another from the Chalk-Pits near Cherry-Hinton in Cambridgeshire. Don. R. Gale Arm. A granulated Marchasite growing on an Ash-coloured Stone pointed into Right Angles. The Tabulated Marchasite flat and plain, like a Table; these are found, naturally squared and polished, in the midst of Lime-stone Rocks in Craven, whence it was sent me by the Rev. Mr. Rob. Hesketh. The Cubick Marchasite, little more than a Quar ter of an Inch Square: It seems to attain the Perfection of its Figure in a Cube.
