A STONE voided from the Penis or Urethra of a Man who lived at Exeter. Given by Dr. Cotton. It is of a whitish colour, and soft substance, almost like Chalk. In length two Inches and a quarter. Of a Pyramidal figure; with an obtuse Cone. Near the Base an Inch over. Where it hath a little Hole or Canale tending towards the Cone. When it first slipped out of the Bladder into the Penis, it was neither so thick or big, nor so hard, but that, as it seems, the Urine pressing forward, forced a hole for its passage through the middle of it. Which being opened, the Stone continued fixed in the same place, viz.about an Inch behind the Glans Penis, for the space of Thirteen Years. In which time, it gradually grew bigger, till it came to the bulk above mention'd. And the said Hole or Canale being by the continual accretion of new matter, at last stop'd up, the Stone was then forced out of the end of the Penis.

The LOADSTONE. Magnes; from Magnesia, a Country between Thessaly and Macedonia, where, it's said, it was first found. For the most part of an Iron-colour, tending to Blew, by some called The Male; if Black, The Female. Here are several both great and small. One weighing about sixty pounds. Given by Dr. Edward Cotton. Dug out of the Ground in Devonshire. Although it takes up no great weight, yet moves a Needle nine feet distant. Some part hereof, which was broken off, being put in its proper place, adds much strength to it. Here are likewise some other great Pieces from the same place.

This Stone was lately sent up out of the said County, and presented to the R. Society by the Reverend Arch-deacon, Doctor Edw. Cotton, with this description, That it weighs 60 pounds; and that, though it take up no great weight, yet it moves a Needle about nine Foot distant. Some part of it being broken off, he hath sent up also, because (saith he) being put in its proper place, it adds much strength to it, but without that addition it moves not much more than seven Foot.
