long and oval than the precedent. BeJIer 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 Cation. 
An EIGHTH, in fhape like a Peftil. The upper part of 
this is knobed, the other fmooth, whether naturally appears 
not. 
Thefe Sto?ies 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 diffolved with Spi- 
rit of Nitre, not without Efervefcence , 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 cali'd Teco- ( c 
lithos. 
Thefe Stones always break flaky, and with a ftrong glofs, 
like a Spar $ or the Entrochm hereafter defcrib'd. 
Of thefe Stones it is further obfervablc, That being cut 
and polifh 'd tranfverjly, and then wetted, they fairly exhibit, 
at lcaft in colour, a twofold fubftance. The one, whitilh $ 
anfwering to the Parhenchyma or Fle(h of a Fruit : the other 
black or dark-colour 'd, not only in the Stalk,but alfo thence 
produced, and difpofed into two Rings, a large one next the 
Circumference, and a fmall one in the centre of the Stone * 
anfwerable to the Lignous Fibers, diftributed in much alike 
manner in fome Fruits. 
Two ftrait flender Stones, refembling the COLUMNS 
erected in the middle of fome FLOWERS. One, Convex 
at the top, and almoft flat. Tile other, fphencally trian- 
gular, fomewhat like the Seed-Cafe of a Tulip. Beneath, 
of an a(h-colour $ upward, of an obfeure or brown Bay. 
Of that hardnefs, that if ftruck or let fall one upon ano- 
ther, they have a kind of Metallick found , like that of 
fmall round Button-Bells. 
Two other joynted Stones of the fame nature with the 
former : looking as if they were pieces of the GENICU- 
LATED STALK of fome Plant. 
'Tis pleafant, efpecially with a Glafs, to fee the wrought 
Work on the furface of thefe Stones. In which the fmall 
and curious Stria which run by the length, anfwer to the
