And truly the Stone of our Giam Caufway agreeing 
fo well in Hardneft, Colour and Subftance with this 
^thtopkk Marble defcribed by ?lin^^ and Kentmannm, 
reducing a fort of Pillard Stvne in M'tfnia near Drefdm in 
Germany^ that nearly refembles ours in many of its Pro- 
perties, to the Bafaltes : I thought I could not more apt-

know areCilyndrical Bodies, and never Angular, always 
of a fmall Size, the largeft not above an Inch Diameter,
