Part III. And Stones li\e them. 
There's one which may be called an E?ithrochite, yet not 
a Stelechite, becaufe Oval, or at leaft fmaller at both ends 5 
no way refembling a Stick or Branch. But there is no 
example hereof in this Mufteum. 
The True STELECHITES, branched. Tis not only ra- 
diated,and furnifhed with a Pith: .but is one fingle piece with- 
out any Joynts or joynted Wheels • in which refpect,it can- 
not be called ENTROCHVS $ but very properly Stelechites, 
( from whence the Englijh word Stalk) as more anfwerable 
to the make of a ftick or ftalk, than are any of the reft. 'Tis 
of an afh-colour, and curiouily wrought all over in the 
like manner as a Poppy-Seed. 
A Piece of a Rock confifting wholly of feveral Species 
of E NT ROC HI or Stelentrochi, immerfed in a bed of their 
Mother-Clay. 
Another, with two or three fmall STELECHITES. 
A hard Stone of the colour of a Magnet, with the figna- 
ture of a TROCHITES. 
Thefe Stones being broken, look flaky, and with a glofs, 
as the Lapis Judaicw 5 but fomewhat more obfcure. They 
alfo make a like Efervefcence with Acids, efpecialiy with 
Spirit of Nitre. And may probably be as good a Diure- 
tic^ That Ail Fojfdes of what figure foever make an 
Ebullition with Vinegar - 3 is affirmed by Mr. Lyfter : (a) but Phil, front* 
was a flip of his,otherwife moft accurate Pen. For there are N ' I06,i 
many, and thofe of feveral figures , which , although 
powder d, yet are fo far from making any Ebullition with 
Vinegar, that neither Oil Of Vitriol, nor Spirit of. Nitre it 
felf, ( which taketh place fometimes where the former doth 
not ) will ftir them : as appears in feveral Inftances in this 
Catalogue. . 
They are found in as great variety here in England, as in 
any other Country. By Mr. Lyfter, in certain Scans in 
Br aught on and Stock.-, two little Villages in Craven : in'fome 
places of the Rock as hard as Marble. In fuch plenty, that 
there are whole Beds of Rock made of them. By Mr. Beau- 
viont, in Mundip-Hills $ in the Rocks, from the Grafs to 
twenty fathome : but moft in Beds of a grey and grifty 
Clay. In a Grotto, five and thirty fathome deep, he obferved 
their growth • which was, from the fineft, and the fofteft 
of the Clay. At firft, they were whitifh, foft, and fmooth.
