The Figures of Plants upon Stone or Coal, are more frequently found; but here is the real Plant it self taken out of a Lime stone Rock at Downham in Craven; and given me by Dr. Hargrave of Coln. A Holly Leaf, whereof the Skin, and parenchymous or pulpy Part, being either rotted, or eaten away by Insects, the Texture of the Leaf appears admirably fine, the surrounding Fibre being very strong in this Plant contributes much to the Fairness. It was therefore the more suprizing, when I found the like delicate Skeleton of one of the tenderer Plants, which is very curious. A Slice of Wood full of small Holes, visible to the naked Eye, and so close to each other, that it is surprising how it hangs together, the woody Remains being as small as Lines drawn with a Pen, like the Limphæ ducts and Air Vessels, as drawn in Dr. Grew's Anatomy of Plants.

Crystalized Spar very curious from the Iron-ores in Cumberland from the Benefactor last mentioned, from whom I received most of the Spars that follow.
