Part III. Arid Stones lify them, 
275 
There's one which may be called an Entbrocbite, yet not 
a Stelecbite, 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 Mufdeum. 
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 refpec~t,it can- 
not be called ENTROCHVS 3 but very properly Stelecbites, 
( 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-coiour, and curioufly wrought all over in the 
like manner as a Poppy-Seed. 
A Piece of a Rock confiding wholly of feveral Species 
of ENTROCHl or Stelentrocbi, 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- 
turc of a TROCHITES. 
Thefe Stones being broken, look flaky, and with a glofs, 
as the Laps Judaicm $ but fomewhat more obfcure. They 
alfo make a like Effervefcence with Acids, efpecially with 
Sprit of Nitre. And may probably be as good a Diure- 
tick. That All Fojfiles of what figure foever make an 
Ebullition with Vinegar is affirmed by Mr. Lyfter : (a) but Phil, Tranfi 
was a flip of his,otherwife moil accurate Pen. For there are N ' l00 '' 
many, and thofe of feveral figures , which , although 
powder d, y et 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,^ in 
any other Country. By Mr. Lyfter, in certain Scans in 
Braugbton 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- 
mont, in Mundip-Hills 5 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 foftefl 
of the Clay. At firft, they were whitiih, foft, and fmooth
