Abstract
A NUMBER of crystals of barytes have lately been acquired by Mr. Henson from Chirbury, Salop, which seem to deserve some description. The crystals vary from one to four inches in length and from one-half to two inches in breadth; they are very bright and clear, and are elongated in the direction of the brachydiagonal, resembling in appearance the barytes from Dufton; they are mostly doubly terminated, and some contain included crystals of copper pyrites. They were at once detected by Mr. T. Davies as being peculiar in form; and the reflecting goniometer revealed the existence upon them of four very well-defined forms which have not been hitherto found upon barytes, besides two more doubtful planes to which it is difficult to assign definite symbols.
