Of Petrify d Plants, Part III 
Afterwards, grew hard, and ridged, or divided into Trochi 
or Joynts 5 beginning at the top, and fo defcending. Be- 
ing all the while in a manner quicken d with Mineral 
Steams $ conveyed, from the Mother-Bed, through the Pith 
of the feveral Feet of the Root (which Mr. Lyfter figures) 
and of the Stock it felf. 
It were alfo further worth the enquiry, In what Time, 
one of thefe Stones will grow up. Whether it doth fo, by 
Starts, as Ice often doth, and as I have feen a little Icy-Tree 
to grow level upon a Table ? And whether fo much as 
ferves for the making of a fingle Joynt, at every ftart ? 
A Stone figur d like a Piece of ANGELICA Root 5 with 
a large Pith, and very diftindt Rays, as the Cortical Insertions 
in that, or other like Root round about. 
TWO leffer round ones or more Cylindrical : one re- 
fembling the Root of CICH0RT h the other of TORMEN- 
TILE. 
A STONE fomewhat FLAT, like the Root of Irk : but 
radiated as the former. More viiible, if one end,being firft 
polifhed, be then made wet 5 for fo, both the Pith and Ra- 
diation are very diftincl:. 
A FOURTH, as it were bared of the Rind $ and having 
one end with a kind of Button, on which the Rays wind 
toward the Centre 3 as the Lines of a Rumb upon a Map, 
or the Suits of the Attire of any Corymbiferous Flower. 
All thefe feem to be feveral ftumps of Stone Roots, on 
which the above defcribed Stones often grow. 
A FIFTH, with a Pith and Rays h but CONICK and 
CROOKED , not unlike the young buded Horn of a 
Calf. 
TWO more of the fame Figure, but much lefs 5 rather 
refernbling a COCKS SPVR. 
Several CLUSTERS (as they appear) of petrify d 
MOSSE. Imperatus y with Diofcorides, makes it a fort of 
Alcyonium. 
A petrify'd TUBER, with feveral fmall papillary knobs, 
not much unlike that called CERVI BOLETVS. It ftirs 
not with any Acid.
