I Havehave drawn the Figures of Two Roman Altars, which my Correspondent in the North transmitted to me for my Thoughts of them; the former was taken out of the Roman-wall, not far from Collerton, or Chollarton*, and may tempt us to believe that the old Procolitia, which was the Station of the Cohors prima Batavorum, was rather there, which is an important Place, (where the River Tine interrupting the course of the Wall it was but necessary that the Foard should be secured by making one of the Cohorts keep that Station), and it is but two Miles and a half from Carrow, (where the Altar now is in the Possession of Mr. Forster) than at Pruddow, which is at least Ten Miles distance where Mr. Camden seem'd to fancy it. The other is at Blenkinsop † Castle in Northumberland, which I take to have been dedicated by Lucius Annius to the Goddess Nymphs Old and Young, and particularly to the Debonair (if Urbana be taken appellatively) Mansueta Claudia; for thus I read it, * Prope Colerton Cilurnum. Notitia Dignitatum imperii, est tamen Procolitia alius locus a Cilurno. † Propè Blenkenshop & Widen, Vettii. Circa hæc loca fontes. Utrumque Nomen hoc indicat. DEABUS (664) NYMPHIS Veteribus ET IV ioribus MANSVET AE C L A V D I A E VRBanæ, nuncupavit Hoc Lucius A IVS; and hereby the Defects in the Stone seem to be supplied with a right Number of Letters in each Vacuity, and this I the rather apprehend to be right, because 'tis now a Year since I communicated the same to an ingenious Gentleman, Dr. Cay of New-Castle (who was the Person that courteously sent me the Copies of both) and I hear not it is disapproved by any Critick upon the Place.

Several Sorts of the Coralline Shrubs, incrustated Plants, from the English Shore: But the most curious of them is that Corallina alba, discovered by the ingenious Mrs. Ward of Gisburgh in Yorkeshire. Others Submarine Plants of different Colours and Substance, growing upon Stones. Warted Sea-wrack, with greater and lesser Bags, or Vesicular Knobs. ... A pounced Plant, two Inches broad and half a Foot long, part folded up; it grows upon a Rock, or rather is fastned to it, for they receive no Nourishment from the Rock, but the Sea Water, and such Nutritive Bodies as it is impregnated with.

A Pod of the Cassia Fistula of the Shops, that comes from Egypt it is smooth, and two Inches round. The Cassia Fistula Americana, or Cassia Brasiliana. This rare Plant (Don. D. Jab. Cay M.

But to return to the West-Indies, Chr. Gale Esq; sent me from North-Carolina some dried Yawpon, which the Indians in those Parts use for Thea, but is not very agreeable to the Generality of English Palates; the Form of the Leaf is not unlike that of Box. The Date-stone altogether solid. The Fruit of the Palm-Tree yielding Wine and Oil.

Rock-Crystal, half a Foot round one Way, and within half an Inch of it, the other. It was brought me from Milan by Dr. Jabes Cay, who observed therein the Modus Concrescendi in the Middle, different from that of the out-side. Sometimes there remains a small Drop in the Middle of a transparent Peble that will never take the solid Form. Of the Iris or lesser Crystals, here are several Sorts, as those called Downham Diamonds, from the Place in Craven where they are found. s S ome are very small, others larger and very great, an Inch and half round; from Dr. Hargrave of Coln. The like Sort of Diamonds from Harrowgate Spaws near Knaresborough: They are found at the Mole-hills (near the Sulphur-well) after Rain; as are also those at Downham.

Lithophyta, five of them having the Impression of Plants, from Mendip Cole-Pits Com. Somers. As many from those at North Byerley Com. Ebor. The Gifts of my honoured Friends Dr. Woodward and Dr. Richardson, some of which are upon Coal-Slate, others upon a harder Stone; of these are the Filix florida, sive Osmunda regalis, Filix Mas dicta, Filix Fæmina. Here is also Lh. ignota Planta Mineralis, Neurophyllon carbonarium dicta, N° 184. but from whence I remember not. But the most distinct are those in a hard Iron-stone from the Newcastle Coal-Pits, called by the Miners Cat-heads, which contain a Fern Leaf, or Polypody very fair; they are found in a particular Stratum, and being struck with a Hammer very readily part in two, and discover the Plant, which is very prominent on one Side, and concave on the other: Of these I have from two Inches to five in Length, the longer hath fifteen Leaves on each Side the middle Rib; one of them is broader and contains four Plants, resembling Lh. Trichomanes Minerale 191. Don. D. Jab. Cay M.D. But the most durable of any of these impressions is one found at Rochdale in Lanc. upon a very hard Iron Stone, whereupon are three of the said Plants very fair. Don. Gul. Clayton. Arm.

The Bivalves. The Ostracites maximus rugosus & asper (k)(k) Idem, p. 236.; one of these is a Foot round, and weighs near ten Ounces, was sent me by Dr. Cay, whose Account of their Vertue in Nephritic Pains is inserted iu in the Phil. Trans. N° 230250. Samples of the lesser Sorts (Don. D. Jo. Woodward) from North Leach, Sherburn, and Barrington in Gloc. with one of the oblong, narrower, and smaller Sort from the same Quarry. A single Valve of the white Stone Ostracites, given me by Dr. Plot, and an entire one well formed of the blewish Colour. A mighty thin compress'd one, yet hath both Sides. A lesser Sort, striated, white and Ash-coloured: One of a yellow Colour, for they vary according to the Delf they are lodged in. A Sort of Tree-Oyster from Barrington Quarry. The Shell of one found on the plowed Lands near Ensum-ferry Com. Oxon. A smaller Sort with thick Striæ. Ostrea minima echinata from Northamptonshire. Don. R R. D D. Episc. Carl.

The Right Reverend Prelate before mentioned, hath obliged me with almost all the Varieties of the Entrochi, that are described by Dr. Lister and Mr. Beaumont in the Phil. Trans. N° 100 and 150, from the Trochitæ, or single Joints, to the Number of 38 or 40, in an Entrochus of near 2 ½ Inches in Length; and as to Thickness from little more than a Pin, to near three Inches. As to the Form, here are perfectly round, exactly Oval, and the Compress'd of different Degrees. Some more gently, others so crush'd (even to the 16th Part of an Inch) that the Cracks are visible. The Joints or Vertebræ of some are strangely dislocated, and in Part slip'd off, as it were, yet adhering to the other Part. Some of the Joints are thick; others so extreamly thin, that they are scarce the 24th Part of an Inch, for I have one of ¾ of an Inch in Length that hath 19. Some again are but seemingly joynted, others, and those the greatest Part are really so, and the Sutures indented. Some even of the longer Stones are without Notches; others thick set with such Marks, whence the Branches of these Rock Plants have issued; but of these out-Branches there seldom remain above two or three Joints. Besides, those that are exactly Cylindrical (equally thick at both Ends), here are some of the Branches tapering at the smaller End. Upon the Surface of many are drawn very fine and small Rays from a Point in the Center to the Circumference. The Pith in the middle of some of them is round, of others, oval; and of the Form of a Cinque-foil in the midst of the Rays in others, and some have six Inlets. To those which are Concave, a protuberant Point in the Center of others doth cor respond. In some the Pith is quite gone; these being put upon Strings are called St. Cuthbert's Beads in the Holy Island, whence Dr. Cay procured me some: He afterwards sent me one, the Medulla whereof is the Pyrites. Some are almost smooth, others have a raised Edge in the Middle of the Joints; others have a sharp Ridge betwixt two smooth round Joints, and so alternately; and some (though rare to be met with) have a Circle of Knots, or small Protuberances in the midst of each Joint: Here is also a red Entrochus with a white Pith, growing upon a Rock of a reddish Colour.

Mr. Lhywd next to the Bufonitæ placeth the Siliquastrum Phaseolatum, so called because it resembles the Pod of a Bean or Pulse; the Surface is black and shining, the lower Side, where it should join the other Valve is a white Stone; it is the first Fig. in Phil. Trans. N° 200. His second is a broader Species, which he Names Siliquastrum lupinatum the inner Part of this is a reddish Stone. Some here are different only in Colour, brown or black, others in Form, being more Gibbose. Here are also the smallest Sort: Most of them sent me by my grand Benefactor, my Lord Bishop of Carlisle. To these Siliquastra, or rather (to use the local Word) single Swads, being but one Valve, may fitly be added the entire Beans; one of these (Don. Jab. Cay M. D.) both in Form and Colour resembles the great Garden Red Bean; the other is lesser, and dark coloured, but both of them; as many of the finer Pebles, are a sort of Touchstone. A third represents a compress'd Bean, and is of a bright brown Colour. The said ingenious Physician sent along with it, the Triorchis, or Stone resembling Three Nuts. To which may be added another in the Form of a Nutmeg, and which is most curious, one from the East-Indies that doth so naturally represent Half a Nutmeg, as well on the Inside, as without, that many Persons will not be persuaded by their Eyes, that it is otherwise, till their Taste convince them of their Infidelity. Don. D. Tho. Wilson Merc. Dublin. A Stone very like a Gall for making writing Ink, and another to half a Ball of Gascoigne Powder.

In the same Tour I observed a Sort of black Marble, the Product of the same County; of which I saw several Gravestones at Leicester, and seems capable of Improvement: Of this I have a Specimen, and of the Sussex Marble, which abounds with white turbinated Shells, and is therefore called Marmor Turbinites, by Dr. Cay who sent it me. Of the Florentine Marble adorned with Trees, see before. Here is a Murrey coloured Marble with white Specks, very beautiful and well polished. Also the Kilkenny Marble from Ireland; it is black with whitish Clouds. This with a Sample of the black Irish Slate, was sent me by Mrs. Marshal of Dublin. A different black Marble, with less white, by Sam. Molineux Esq;. Another Sort from Bolton in Craven, of which I have seen a Chimney-piece at the Lord Fairfax's at Denton, that looks very well. Two Samples of Darbyshire Marble (Don. Jo. Battie Arm.) one pale Red, with white Veins; the other curiously variegated with black, white and sad Colour, in which is the Figure of a Pyramid, &c. Of which Sort is a very curious Chimney-Piece at Alderman Atkinson's in this Town. A Marble Table with the exact Figure of the Belemnites upon it.

To Marble may fitly be added Alabaster, which some Naturalists account marmor incoctum sive imperfectum: Of this here are clear white of different Thicknesses, and white, with red Veins, and brown Spots, dug up at Fairburn near Ledston in this Neighbourhood. A globular Flint, of the Colour of Amber without, and a large Oval one, that within hath a Spar-like Substance, sent from Newcastle, by Dr. Cay. Lapis Armenius, or a Sort of Native Blew, of which Cæruleum nativum, see Dr. Plot (d)(d) Nat. Hist. of Oxon, pag. 57 & 161.. Don. Rog. Gale Arm.

A Lough Neagh Stone sent me from Ireland by the late Reverend Mr. Tho. Jackson. It is a Piece of Holly petrified, but whether by the Water of the Lough, or the Soil where it is found for about two Miles round it, is uncertain: See Phil. Trans. N° 158, and N° 174. A Fossil sent by the Name of Petrified Wood from Portland Quarry. Another from Crick Com. Northampt. And a third from an Encrustating Spring near Harrington in the same County, all presented to me by the Learned Dr. Woodward. Petrified Moss from the Dropping-well at Knaresborough in the West-Riding of the County of York, which a noted Physician says, is the most famous Petrifying Spring in the Kingdom (f)(f) Dr. Wittie's Scarb. pag. 54.. White Pumis-stone; there are also Ash-coloured and black, near Mount Vesuvius. Cinders from Mount Ætna, both of the Black and Red. Don. Tho. Sanders Arm. Other Sciarri, more Metallick. The like from Vesuvius, brought thence by my kind Friend Dr. Jabez Cay. This Sample hath more of the Pyrites in it. Sparkling Metallick Ashes from the same Volcano. A vitrified Substance almost in the Form of Garlick or Lilly-Root. In the Phil. Trans. N° 296, is an Account of the vitrified Cinders of a great Hay-rick burnt upon Salisbury Plain: Here is the like from Sir Edw. Blacket's at Newby in this County. Cinders from Almonbury, when old Cambodunum was burnt by the Pagans, of which see Bede and the new Britannia: It appears by these that the Flame was so vehement, that the Earth was melted rather than burnt.

Iron Ore that I brought from Egremont in Cumberland, from whence it is transmitted to Ireland, where it is smelted. A Piece of an Iron Bolt found in a Stone Quarry, and now returned to Iron-Ore again; this being a Property that Iron hath, and no other Metal, as Dr. Lister observes in his Journey to Paris. Don. Ja. Cay M. D. A Ferruginous Body from beside Worcester; and another from a Clay-Pit at Richmond in Surrey. Don Jo. Woodward M D.
