In the same Tour I observed a Sort of black Marble, the Product of the same County; of which I saw several Gravestones at Leicester, and seems capable of Improvement: Of this I have a Specimen, and of the Sussex Marble, which abounds with white turbinated Shells, and is therefore called Marmor Turbinites, by Dr. Cay who sent it me. Of the Florentine Marble adorned with Trees, see before. Here is a Murrey coloured Marble with white Specks, very beautiful and well polished. Also the Kilkenny Marble from Ireland; it is black with whitish Clouds. This with a Sample of the black Irish Slate, was sent me by Mrs. Marshal of Dublin. A different black Marble, with less white, by Sam. Molineux Esq;. Another Sort from Bolton in Craven, of which I have seen a Chimney-piece at the Lord Fairfax's at Denton, that looks very well. Two Samples of Darbyshire Marble (Don. Jo. Battie Arm.) one pale Red, with white Veins; the other curiously variegated with black, white and sad Colour, in which is the Figure of a Pyramid, &c. Of which Sort is a very curious Chimney-Piece at Alderman Atkinson's in this Town. A Marble Table with the exact Figure of the Belemnites upon it.
