A Lough Neagh Stone sent me from Ireland by the late Reverend Mr. Tho. Jackson. It is a Piece of Holly petrified, but whether by the Water of the Lough, or the Soil where it is found for about two Miles round it, is uncertain: See Phil. Trans. N° 158, and N° 174. A Fossil sent by the Name of Petrified Wood from Portland Quarry. Another from Crick Com. Northampt. And a third from an Encrustating Spring near Harrington in the same County, all presented to me by the Learned Dr. Woodward. Petrified Moss from the Dropping-well at Knaresborough in the West-Riding of the County of York, which a noted Physician says, is the most famous Petrifying Spring in the Kingdom (f)(f) Dr. Wittie's Scarb. pag. 54.. White Pumis-stone; there are also Ash-coloured and black, near Mount Vesuvius. Cinders from Mount Ætna, both of the Black and Red. Don. Tho. Sanders Arm. Other Sciarri, more Metallick. The like from Vesuvius, brought thence by my kind Friend Dr. Jabez Cay. This Sample hath more of the Pyrites in it. Sparkling Metallick Ashes from the same Volcano. A vitrified Substance almost in the Form of Garlick or Lilly-Root. In the Phil. Trans. N° 296, is an Account of the vitrified Cinders of a great Hay-rick burnt upon Salisbury Plain: Here is the like from Sir Edw. Blacket's at Newby in this County. Cinders from Almonbury, when old Cambodunum was burnt by the Pagans, of which see Bede and the new Britannia: It appears by these that the Flame was so vehement, that the Earth was melted rather than burnt.
