Sulphate of Strontian
- Class 2. Earths.
- Order 1. Homogeneous.
- Gen. 6. Strontia.
- Spec. 2. Sulphate of.
- Div. 1. Crystallized.
The plated Sulphate of Strontian here figured is in a sort of sandy matrix, and was the first specimen I received from Mr. Clayfield. It is like that which I first had from Mr. Tobin, excepting that the latter was in much larger pieces, without matrix, and nearly white. The crystals are mostly confused, yet are occasionally found very neatly determined at two or three sides, as in this specimen.
The geometrical sketch at the bottom shows the bevelling at the corner, between the primitive faces.
This kind is chiefly found at Redland near Bristol.
