ANOTHER of the fame. And alfo with a double 
Ring of Rays ; fo as to look like one of thefe Stones within 
another. And may therefore ot all the kinds, be moft pro¬ 
perly called ENTROCHITES. 
A FLAT ENTROCHITE. All the former are per¬ 
fectly round: this comprefs’d; one way, an inch over; 
the other, about * ths . 
ANOTHER, a finall one of the fame fhape. 
A THIPvD, not only flat, but alfo with two oppofite 
edges, like the Scabbard of a Rapier. 
The BRANCHED ENTROCHITE. Yet here the 
Branches, which grew alternately as Twigs on a Bough, are 
broken off. In one, leaving fo many cavities in the Trunk. 
on which they grew. In another, fo many Knots. In both, 
radiated, and containing a Pith, as the 7 rank. it felt. 
The KNOTED ENTROCHITE. A very odd Species. 
Above two inches long, and I in Diametre. The Surface 
fmooth, yet with an obfeure appearance of Joynts. The 
Knots, no way like thofe in the lall mention’d, as not being 
radiated; and looking more like the bafes of fturdy Thames. 
Wherewith it not unaptly refembles a piece of a Crab-Tree- 
Cudgel. Tis compofed of three diftinct fubftances. The 
outer part, ( as one would fay, the Barque) is a flaky and 
glofly Spar, as in the reft. But as black alrnoft as Jet. The 
middle part is Ore of Marcafite,ox Tel/ow Mundick- The Pith, 
not unlike Tobacco-Pipe-Clay , when baked pretty hard. 
A fort not much unlike thefe, being found in the Ifle 
Malta , by fome faith Mr. Ray, (a) are call’d St. PAULS 
BATTOONS. 
The SYNTROCHITE, as we may name it, to diftin- 
guifh it from the reft. It confifts of feveral Joynts as the 
former; yet not piled evenly one over another fo as 
to make a Cylinder: but fliden as it were half on and 
half off. 
The TROCHITES. ’Tis nothing elfe but one of the 
above defenbed Joynts Angle; on both fides radiated, and 
alfo containing a Pith. So that it looks like a flice of a flick. 
Thefe, faith Mr. Lyfter, being ufually hollow, or eafily fo 
made, and ftringed, are therefore by fome called St. CUTH- 
BERDS BEADS. 
The ASTROCHITES. As it were, the Trochites and 
the AJleria (hereafter deferibed) together. That
