The BRASILIAN MOOR-HEN, called Jacana. Given by Dr. Richard Lower. See Marggravius's Description hereof. The Colours not the same in all parts, as in that of Marggravius; the hinder part of the Back and Tail being here of a bright Bay or Chestnut, inclining to red: in his, only black and green mixed. Perhaps depending on the difference of Ages as in the Guara. The Membrane wherewith he saith the Head is cover'd, in this, growing on the Bill, is extended only over the Forehead like an inverted Peak. He saith, that on all the four Toes there grows a Claw, ½ an inch long: whereas the Claw of the hinder Toe or Heel is at least an inch and ½ long. On the fore Joynt of each Wing, grows a Spur, as in the Anhima; but not above ⅓d of an inch long, round, and exceeding sharp. Which is omitted also by Marggravius, but mention'd by Piso. She is remarkably distinguished from all other Birds, by the slenderness of her Legs and Toes.

SOAP-STONE: Steatites. Given by Dr. Richard Lower. Taken from a Rock of the same in Cornwall. Somewhat different from that described by Boetius. Consisting of parts white, red, purple, and green mixed together, as in Castile-Soap; and seeming, like hard Suet, greasie to the touch: whence the reason of both the Names. Yet is it not at all dissoluble either in Oil or Water. Nor in any indifferent Fire; by which it only becomes somewhat harder and whiter. It seems to me to be much of the nature (for substance) of the Lap. Amianthus; and that it is the Mother of it.
