Note 10 — PETER KALM’s TRAVELS. (continued 2)

I received to day, several curiosities belonging to the mineral kingdom, which were collected in the country. The following were those which were most worth attention. The first was a white, and quite transparent crystal.10 Many of this kind are found in Pensylvania, in several kinds of stone, especially in a pale-grey limestone. The pieces are of the thickness and length of the little finger, and commonly as transparent as possible. But I have likewise got crystals here, of the length of a foot, and of the thickness of a middle-sized man’s leg. They were not so transparent as the former.
