Sulphate of Strontian

  • Gen. 6. Strontia.
  • Spec. 2. Sulphate of.
  • Div. 2. Imitative.

We have represented the following varieties of this substance, to show those most generally known, at least in Great Britain.

The upper figure is from Aust Passage, near Bristol, and its curved appearance renders it at first sufficiently curious, besides its partaking of the blue and red colours.

The striated Strontian in the middle figure seems to answer to the name of Cœlestine, as Werner calls it, more generally than the last, as it is here coloured.

The fibres in this sort, which comes from Breslington, are very straight, and somewhat laminated.
