HEREHere are most of those observed by the learned and accurate Dr. Lister, in this his Native Country, together with others from Westmoreland, Glocester, (Lassington-stones), and Northamptonshires. Mr. Moreton's third Sort called Peter-stones. Here are of the Litorales, as well as Arvenses, but the most of them from the Foot of the Yorkshire Woulds. The largest of them is scarce an Inch and half long, wherein are 17 Joints; but here are others with so very thin Joints that there are 16 of them in ¾ of an Inch. Some are very small, yet of five Rays, others an Inch and half in Circumference. The single Joints have sometimes the fairest Figures of the Stars, consisting of five Angles; the middle of each of which is a little hollowed, and the Edges more prominent and thick furrowed, by which the several Joints are knit together, the Ridges and Furrows being alternately let into one another; in the Center of the five Angles is a Hollow or Point. Of these, piled one upon another, are made pentagonous cylindrical Columns. Dr. Plot says, to the Number of 15, in which Number yet he wants 7, that is, he found none of 5 Joints, nor of 7, 9, 11, 12, 13 or 14 (e)(e) Plot's Oxon, p. 86.. But I have a distinct Column of every Number, from the single Joint to 18; and in them most of the Sorts so accurately described by Dr. Lister (f)(f) Phil. Trans. N° 112., except with the Wires adhering; but here are of the Wires, though broken off, both in single Joints, and longer Pieces, which are very small, slender, and of a round Figure, being set together not by indented Suture, but per harmoniam (g)(g) Idem, p. 277., like the Antennæ of Lobsters. Others smooth from the Shore of Hull. Most, if not all of these Columns, are visibly bent and inclining. The Angles of some of them are more obtuse, of others more acute, and consequently deeper chanell'd, than where the Angles are blunt and round. Here is also a third Sort that is very rare, which have five flat Sides without any Indentings in the Form of a Star. Some of both Sorts have a small Pin-hole in the middle of each Joint, betwixt Angle and Angle. Others the more rarely have a Knot, or Joint of Wires remaining at some of the Holes. Some again have each other Joint more protuberant, or standing further out than the intermediate ones. The Asteriæ are of different Colours acording to the Matter they are found lodged in, as white, brown, blewish and ash-coloured. A ferruginous Body that seems to be Lh's. Siphunculus cylindracius ferruginosus, N° 1212, from Welsale in Staffordshire. A much less from the Shore of Hull.
