Of the Nautelites, by the Ancients called Cornua Ammonis (for its resemblance of the curled Horns of the Ram, worshipped by the Name of Jupiter Ammon in the Deserts of Africa:) Here are various Sorts, of different Colours, Figures and Sizes, from less than half an Inch to half a Foot in Diameter; but all so curled up that the Tail of the Snake is in the Center of the Stone. The small Sort, whose Parts are protuberant and swelling to a Round; of these are both the Ash-coloured, and the brown (from my Lord Bp of Carl.) the Striæ of each Colour are single near the Center, but presently divide into two Lines, but terminate in a single Lineation. Of the same Form are a greater Sort that are six Inches in Circumference, and very fair. These of the Ash-coloured Stone, appear in Places to be adorned with a shining brazen Armature, as is more evident by an Arch, or Part of another of the same Kind. A Segment of a large one with single Striæ of an Iron-stone; it is 4 ½ Inches round. One that is more thinly striated, but the Lineations are larger and more prominent, like N° 10 in Dr. Plot's 5 Tab. Nat. Hist. Oxon. On the other Side is no Figure, being of Dr. Lister's 9th Sort (g)(g) De Lapid. turbin. p. 212, ex altera tantum parte ad umbilicum cavus. Of those that are depressed; here is one of five Wreaths, three Inches broad; and another near half a Yard in Circumference, which was the largest I could conveniently bring from Whitby; both these which are an Ash or blewish Stone are of the Cornua Ammonis pertusa, being perforated at the Center; they have also a Crest or sharp Ridge, like the Spina Dorsalis; on each Side of which is a Furrow or Channel. A Fragment of a small one with as many Wreaths. The Segment of a larger, being half a Foot round; my kind Benefactor, Dr. Woodward, received it from Whitton Com. Linc. as he did three Samples of the lesser Sort from Lansdown, near Bath. My Lord Bishop of Carlisle sent me, amongst others, the smallest I have seen, being but a Quarter of an Inch broad, yet fairly striated. A larger with six Wreaths. Mr. Sutherland of Edinburgh sent me a small compress'd one, found about ten Miles from the City. But here is another Species, considerably different from all the former, the middle Part being sunk in, or depress'd to a great Depth; the outmost Wreath is above two Inches broad, the Center on each Side is dip'd in, an Inch deep; it is near eight Inches in Circumfe ferencerence. A small one of the same Sort, but one Inch broad, and of a shining Colour. Here are also the Matrix or Beds they are lodged in, somewhat globular, and without any Impression on the convex Part, but finely striated within, after the Form of the Stone it self. The most remarkable of which was given me by Dr. Sawry of Yorke, who received it from Whitby; it is a Congeries of them in an oval Brass Lump (as commonly called) a Quarter of a Yard round, containing the gilded impressions of seven of them.

THEThe Cochlites of four Wreaths, part of the Shell remains upon the Clavicle of one of them. Don. Rog. Gale Arm. The Buccinites, the small striated one of Dr. Plot (h)(h) Nat. Hist. Ox. Tab. 4. 2.. A larger, plain; both from my Lord Bishop of Carlisle. All above are Stones, but here are also the Shells both of the Cochlea Kind, and the Buccina, fill'd with Pyrites, from a Clay-Pit at Richmond in Surry. Don Jo. Woodward M D. As also others from the great Sand-Pit at Woolwich in Kent. The smallest Turbinites from Northamptonshire, and three Turbinated Stones, with a plain Superficies curiously turned in the Form of a Spiral Cone, like a Scrue or Steel-worm for drawing Corks out: One of half an Inch long, hath five solid Wreaths. These were from the Portland Quarry. One of near three Inches taken out of a great Stone at Oswald-kirk Com. Ebor. Don. D. Fr. Place. But the largest of all the Buccinites (above three Inches round) was sent me with many rare Fossils, by my Lord Bishop of Carlisle. It is Dr. Lister's 14th (i)(i) De Lapid. Turb. p 216.. Some curious ones very small, from Scotland. Don. D. Jac. Sutherland.

The Tellenites: These are distinguishable enough from the Pectunculi by their oblong Form; but from the Musculites, and some Sort of the Ostracites, it is more difficult to distinguish them. Very fair ones from Scotland. Don. D. Jac. Sutherland. Tellina minima, Nat Hist. of North, Tab. VI. Fig. 12. The Trigonella: The Name discovers its Triangular Form; the larger and lesser Species. Don. R. D. Episc. Carl. These have a smooth Surface, and bright. The Terebratula are striated, more gibbous, and the Margin thicker, with the middle Part depress'd or elated. The Stones divested of their Shells, Margine sinuato, Lh. 830. from Boston Com. Linc. Don. D. Hen. Thomson. A small one found in the midst of a large Stone at Coxwold School Com. Ebor. Don. D. Hey. A very large one, five Inches in Circumference, from Dr. Hargrave of Coln. Others of different Sizes, Lh. 829. with transverse Striæ. A thin Shell including Chalk, with the Bill perforated (whence the Name.) Don. Rog. Gale Arm. The Pholas amygdaloides. Lh. 878. The Solenites, so called from its resemblance of the Solen or Sheth-shell (n)(n) Lister, p. 192., or perhaps Conchites Mytuloides (o). This and(o) Lhwyd, N. 878. the Pholas were from Heddinton. Don. Rev. Cav. Nevile.

A dark coloured Stone with red Veins, and black Clouds, with some shining Particles; it was found with three more near a Brook in the North of Scotland, Fourscore Miles from Edinburgh, whence it was sent me by Mr. Ja. Sutherland, Intendant of Her Majesty's Physick Garden there, who sent one to Mr. Lhywd for the Musæum at Oxford; and another to Mr. Charlton for his at the Temple in London; the Curiosity of it is, that it smels strong of Violets, or the Florentine Iris Root; and if put in warm Water communicates its Scent thereto, without diminishing its own.

Mr. Lhywd takes the said Adder-Bead Amulets, to be a notable distinguishing Mark of the British Nation, and the Elfes-Arrows of the Scotch. These are of Flint in the Form of an Arrows Head, and are sometimes set in Silver, and worn as Amulets, against being Elf shot, Phil. Trans. N° 269. For their Opinion in this Matter is, that the Fairys (not having much Power themselves to hurt Animal Bodies) do sometimes carry Men into the Air and employ them in shooting Men and Cattle. This was sent me by Mr. Ja. Sutherland of Edinburgh. Another I received from the Reverend Mr. Clegg near Buxton in Derbyshire, where they are frequently plowed up, and are there called British Arrows. Here is also an Indian Arrow armed with a Flint like these in Form, but an Orange Colour. Mr. Lhwyd also informed me by Letters (July 1702), that the High-landers do at this Day use also the Echinites Galeatus, and the Pileatus, as Amulets; the former they call the Stone of Victory, or Duel-stone, and the other they esteem as efficacious in preventing Damage by Fire or Water; here is one of either Sort. And to shew how difficult it is to obliterate superstitious Customs that have been once received in those darker Ages, here is a Stone that, because it hath two Holes naturally formed therein, some of the Vulgar, even in these Parts of England, apprehend, if tied about the Neck of any bewitched Animal, will unspell the Charm. Don. Rev. Jo. Astley. An ancient Statue, the Remains whereof are now in this Musæum, was defaced by the superstitious Conceit of the Boors, who finding it under Ground, concluded it a Token of concealed Treasure; to discover which they bound Withys or Wreaths of Straw about the poor Roman Knight, and burnt him in Hopes of a Discovery of the Treasure by some Magical Apparition in the Smoke, which Notion seems a Relick of the Heathen Λιβανομαντεία, or Divination by Smoke or Incence.
