Part III. Of Regular Stones. 3 03 
white Ambar. They are found in Germany, and other 
Parts, fonietimes in England. They all make a ftrong Effer- 
vefcence with Acids. Thus far of Stones limply Conick* 
The WORME-STONE. Tis now broken at one end, 
yet about two inches and I long. Confifteth of about five 
folid Rounds, winding from the bigger end ( about I of an 
inch over ) fo as to make a fpiral Cone. Not much unlike 
a Steel Worme ufed for the drawing of Corks out of 
Bottles. 
Another of the fame lhape and bignefs.- This Stone I find 
neither figur d, nor mention d by any Author, faving only 
Olearius. (a) They were taken out of the midft of a (*) A Dutch 
Rock Mufeuna. 
A NETED-STONE. Lapp, retiformm It confifteth of 
black and roundifh portions, feverally furrounded with 
Veins, of an Okre-colour, running one into another after 
the manner of Net-work. Along the middle of each Vein 
( about * th of an inch broad) runs a fmall Thread or Line, 
almoft of the fame colour. 
Another, with the Are 3 as of the Net-work, not fo black, 
fofter, and fomewhat flaky. 
A FLINT of a dull Red, with the Figure, almoft, of 
a a encompaffed with fix or feven Rings. 
The FLAT BOLTHEAD. Anchorites. Of affinity with 
that well defcribed by Wormius (b) with the Title of Silex (*) MuC lib. 
uenabuli ferreum Cuff idem exaffe referens. By Mofcardo, (c) ^ ,2 ' 
with that of Fief re Ceraunie $ who alfo figures it with three CO Muf.iib. 
or four Varieties. This like triofe, is a perfect Flint, and 2 * c " 5 °' 
femiperfpicuous. Tis likewife in the fame manner, pointed 
like a Sfeer. Having at the other end, like thofe of Mof- 
car do, a fhort Handle. But moreover, hath this peculiar, 
that 'tis pointed or fpiked alfo backward on both fides the 
Handle $ with fome refemblance to an Anchor, or the Head 
of a Bearded-Dart : from whence I have nam'd it. Tis 
likewife toothed on the edges , and the fides as it were 
wrought with a kind of undulated fculpture, as thofe before 
mention d. 
ANOTHER, different from the former , in that it is 
longer, hath a deeper Indenture, but no handle. Both of 
them ftrike fire like other Flints. That of Wormius was 
found in a Hill in the Diocefs of Ripen.
