Of C P etrijy'd Plants. Part Ilf. 
The petrify d Barque of a Tree. Tisthin, androwled 
up as Cinamon 5 but rather of the colour of that called 
Winter ones. Withall, rough and knobed without. 
A Piece of Oaf BARQUE cover’d with a (tony Cruft. 
Given by Philip Packer Hep. From a Stump above Ground. 
In Septalinss Mufaum , as I take it, is mention made of 
Petrify d Wood found an hundred and forty Patches un¬ 
der the top of a Mountain. And by Kentman (a) of a 
fort ol petrify d Beech (as the people call it) both Trunk, 
Branches, and Leaves, taken ( for Whetjlones ) out of the 
Ground in the Joachimicf Vale , an hundred and feventy 
Elns depth. But what kind of Eln is here meant, is not 
certain. 
Of petrify’d Woods it may be noted, That none of 
them (at leaft of thefe here deferibed) will make the leall 
Ebullition with any Acid. Which would make one fuf- 
pedt, That they are Stones originally, fui getieris 5 elle it 
were ftrange, That forne of them Ihould not lie in places 
where fuch Stones are bred, which with Acids make the 
laid Ebullition. 
The STELENTROCHITE. By fome, called STELE- 
' HITES : Entrochites , by moft. But, in proper fpeaking, 
diftindf from both. For it is not only of a Cylindrical 
Figure, or near it, and containeth a fofter fubftance in the 
Centre, anfwerable to a Pith: and alfo radiated as the 
Branch of any Tree cut tranfverfy. But moreover con- 
fifteth of feveralflat roundJoynts like little Wheels, evenly 
pil d, and, with the faid Rays , mutually indented, fo as 
altogether to make a Cylinder. Deferibed alfo by Gefner, 
(P) Boetius , (c) Ambrofinusfd) and others. But we have 
two Accounts hereof given us in the Philofophical Tranf- 
aStions, far more accurate and particular, than is elfe- 
where extant. The former, by Mr. l.yjler 5 (e) together 
with between thirty and forty Figures of their Varieties, 
with fome other Congenerous Stones. The latter, by 
Mr .John Beaumont (f) Junior 5 who hath added the De- 
fcription of fome more Diverlities. And the manner of 
their growth. In this Mujdum are feveral Species , which I 
iliall here enumerate. 
A ROUND one, near’of an inch Diametrc; with the 
Pith near a y of a darker colour, hard and denfe. The
