long and ovahhan the precedent. Bejler two or three Stones 
fomewhat like this, which he calls Petrify d Olives. 
A SEVENTH, of a long (lender Figure, and knobed as 
the reft, almoft like a Hazel Catkin. 
An EIGHTH, 111 fhape like a Peftil. The upper part of 
this is knobed, the other fmooth, whether naturally appears

Thefe Stones either grow chiefly, or were firft taken no- 
tice of in Judea $ from whence their Name. They are 
commonly found, not in Earth, but in the Clefts of Rocks, 
by thofe that work in them. They are diilolvcd with Spi- 
rit of Nitre, not without Effervescence , efpecially when 
reduced to powder. And may therefore be juftly efteemed 
Diuretic!^ and fo fometimes bring away,or (as people think) 
break the Stone : for which, by Pliny, (a) 'tis call'd Teco- 
lithos. 
Thefe Stones always break flaky, and with a ftrong glofs, 
like a Spar 5 or the Entrochus hereafter defcrib'd. 
Of thefe Stones it is further obfervable, That being cut 
and poliih'd tranfverjly, and then wetted, they fairly exhibit, 
at leaft in colour, a twofold fubftance. The one, whitifti 5

Circumference, and a fmall one in the centre of the Stone $ 
anfwerable to the Lignous Fibers, diftributed 111 much alike

Two ftrait llender Stones, refembling the COLUMNS 
erected in the middle of fome FLOWERS. One, Convex 
at the top, and almoft flat. The other, fphencally trian-

of an alh-colour 5 upward, of an obfeure or brown Bay. 
Of that hardnefs, that if ftruck or let fail one upon ano-

fmall round Button-Bells. 
Two other joy?ited Stones of the fame nature with the 
fo rmer : looking as if they were pieces of the GENICU- 
LATED STALK of fome Plant.
