The FLAT CENTRE-SHELL. Balanus compressa. Commonly called the BARNACLE-SHELL; and CONCHA ANATIFERA. Because supposed to be the Egg of the Barnacle. And by some (b) (b) Hector Bœthius quoted by Gesner, and our Countryman Dr. Turner. it is confidently deliver'd, that in the Orcades there are certain Worms grow in Hollow-Trees, which by degrees obtain the Head, Feet, Wings and all the feathers of a Water-Fowl, which grows to the bigness of a Goose. Scaliger also describes this (supposed) Bird within this shell. (a) (a) Exercit. 59. toward the end. And with respect to so worthy a Person as Sir Robert Moray (who never meant to deceive) I my self was once induced to publish his Description of the same. (b) But having examined the Shell it self, I am of Opinion, (b) Philos. Transac. N 137. That all that is said of a Bird, is fabulous. Bartholine (c) would have it to belong to a kind of Cancellus. But I rather (c) Histor. Cent. 6. agree with Columna, that it is a sort of Centre-Shell; as being fixed in like manner upon it's Base, and composed of several shelly parts.

ANOTHER of the same sort, of an Oval Figure. Given by Sir R. Moray.

A ROCK of DIAMONDS. Given by Sir R. Moray. They grow upon their Bed (which is about three inches broad, and four in length) in Crystals Sexangularly pointed. Of several sizes from the thickness of a midling Pin, to a ¼ of an inch Diametre, but all of them short. Not very perspicuous, but a little greyish, like the Calcedony. Saving one small cluster of them, tinctur'd yellowish. They cut Glass very deep and easily.

The BASTARD-DIAMOND. Pseudo-adamas. Now remaining, as it was found, bred in a Musculites, a Stone like a Muscleshell. Given also by Sir Robert Moray. 'Tis angular, pointed, and very clear. And cuts Glass with great ease and depth. Of our Bastard-Diamonds here in England, the Cornish are the best; much better than those on St. Vincents Rock near Bristol.

An AMETHYST of a pale Violet colour; found growing in Scotland. Given by Sir Rob. Moray.

A YELLOW TIN-SPAR from Ireland. Given by Sir Rob. Moray. The several Crystals are angular, pointed, and soft; semiperspicuous like brown Sugar-Candy. Dissoluble with Acids.

A SPAR with CONICK CRYSTALS. They are most of them an inch and ½ long. All very close and continuous, excepting at their Points, as in the Amethyst. Semiperspicuous, and exactly of the colour of the best brown Sugar-Candy. Very soft; and easily dissolved with Spirit of Nitre. It was taken out of a Portland-Stone; and given by Sir Rob. Moray.

The STARRED WAXEN-VEIN. Given by Sir Rob. Moray. Found in the Isle of Sheapy. On one part of the Stone grows a fair Star, with many Rays, about an inch long, white and glossy: from whence I name it. This Star is of a quite different nature from the Stone on which it grows, as making no Effervescence with Acids, and in figure agreeing rather with the Pyrites.

CUMBSIMLOCK ORE, Black, and most of it Granulated, immersed in a blackish Stone, dispersed throughout It holds twenty eight lib. sterling per Tun. This, and some other Welsh Ores, given by Sir Rob. Moray.

BULLATED COPPER, Native, or from the Mine. Given by Sir Rob. Moray. 'Tis pure and of the colour of the best concocted. Whether this piece was not fluxed by some subterraneal fire may be question'd. Of the rest, 'tis plain to the contrary.

Pure MASSY COPPER from the Mine. Given by the same Hand. It grows to a white and semiperspicuous Spar, which cuts Glass easily, and deep.

BLACK COPPER ORE, immersed in a Blackish Stone, which is flaked somewhat like Lead-Ore; probably a courser sort of Cinnabar. Given by Sir Rob. Moray.

LEAD ORE, rich in SILVER. Given by Sir R. Moray. 'Tis of the usual colour, but mixed with white Spar, so hard as to cut Glass. And I suppose, that most Lead Ores with such a Spar, have Silver in them.

A Piece of Jet. Gagates, from Gaza a River of Lycia, where first found. Given by Sir Rob. Moray. Of a shining colour, and in some places, flaky. It cracks when held to the fire; and in it, burns with a thick flame and smoak, and very stinking. If rub'd till its warm, it takes up pieces of Feathers, and such light Bodies. 'Tis found in France, Sicily. And in this Island, in Cleaveland, on the top of Huntley and Whitby Clifts, where the Sea-water never comes.

A Pair of WOODEN-BELLOWS. Contrived to save Leather. Given by Sir Rob. Moray. They may be compared to a Box; saving, that here the Box moves, and strikes not within, but over the Lid: and both of a square Figure. The length of the Box from end to end, within, two feet. The breadth, at the Breech, a foot and ¼; the depth, about a foot. The breadth of the Nose-end, seven inches and ½. The Breech-Board is bended, so as to make part of a Zone, answering to the Lid (which moves upon an Iron Centre or Axis) as the Radius.

A BOX-HIVE. Given by Sir Rob. Moray. But contrived by Sir Christopher Wren: And the Description hereof first published (d) (d) By Mr. Hartlib. in the Year, 1652. Since then by Mr. Moses Rusden. Design'd to keep them warmer, and more safe; but especially, to prevent their Swarming, and the better to propagate them into Colonies.

Sir Robert Moray's HEAD in WAX. Taken off of a Plaster-Mold, which was made upon it.
