Th^' farticulars fet forth in thefe Figures ^ mort 
than vphat have been ohfervd by other men^ its 
reference to thof eKock^^hntSy are as follows^ 
1. A Curious 'B^dix fomewhat more entire than elfewhere to be 
faund, on which t ho fe Kock*lpUm$ /ometmes grow ^ th^^ 
it he manifeji that they often grow alfofrom plain l^ots. 
2, Several diverjifyed tops of other Radix*S. 
5. The manifeft tapering of thoje Rock-plants. 
4. Bores of thofe^Qck'^Xmts^ with f our » Jix^ andfevenin^ 
lets in them £ together with other differences in their I{ayss> 
and "Joyntings, 
The particular Explanation of Figures you will find 
beneath^ tho* it be but Qiort^ and not fo full as the defcri-^ 
ptions I have given of thofe ^ock^plants in my fornier Let, 
eers, to which I remit the Curious Reader, 
The main confideration concerning thefe figui' J Stones, 
which I call ^cJ^plants^ isr whether they are parts of 
Plants* or Animals petrifyed, or lapides fui generis ^ to 
which latter opinion I incline: Indeed the figur'd roots 
on which thefe I{pck^plants fometimes grow ( as appears by 
the impreffions of Rays on their tops , anfwering to thofe 
in the Joynts of tlie Plants, and by the impreffions of oval 
Joynts therej may give us Tome fufpicion that they once 
belonged to an Animal^ whether it were a fpecies of ihQ 
Stella Arborefcefis ^ or (bme other > but thofe trunks of 
ftone Plants which you will find in the defigm cannot be 
looked upon as parrs of Animals, with the-ka^ft fhew<>f 
probability, and I think them alnioft as hardly reducible 
to any known /^m^x of Vegetables 5 confidering thac be^ 
li6^s the bores of fome of thefe with four, five* fix, and 
ftve> inlets in them, and beGdes their admirably diverfify- 
joyitings, fcarce either of them to be matcht in any 
Yegetaile 5 I have by me above twenty, if not thirty fpe-
