Part III. Of Regular Stones. 505 
white Ambar. They are found in Germany, and other 
Parts, fometimes in England. They all make a ftrong Effer- 
vescence with Acids. Thus far of Stones (imply Conick. 
The WORME-STONE. Tis now broken at one end, 
yet about two inches and * long. Confifteth of about five 
folid Rounds, winding from the bigger end ( about * 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 dime Ihape and bignefs. This Sto?w I find 
neither figur'd, nor mention cl by any Author, faving only 
Oleariw. (a) They were taken out of the midft of a (*) A Vutch 
Rock. 
A NETED-STONE. Lapis retifomm. It confifteth of 
black and roundiih portions, feverally furrounded with 
Veins, of an Okre-colour, running one into another after 
the manner of Net-works 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' as of the Net-work^ not fo black, 
fofter, andfomewhat flaky. 
A FLINT of a dull Red, with the Figure, almoft, of 
a a encompafted with fix or feven Rings. 
The FLAT BOLTHEAD. Anchorites. Of affinity with 
that well defcribed by Wormius (b) with the Title of Silex (h Muf. lib. 
venabuli ferreum Cufpidem exatle refer ens. By Mofcardo, (c) I'f^'/*' 
with that of Pietre Ceraunie 3 who alfo figures it with three 00 Muf. lib, 
or four Varieties. This like thofe., is a perfect Flint, and 2 * c * 5 °* 
femiperfpicuous. Tis likewife in the fame manner, pointed 
like a Speer. Having at the other end, like thofe of Mof- 
cardo, a fhort Handle. But moreover, hath this peculiar, 
that 'tis pointed or fpiked alfo backward on both fides the 
Handle 3 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 
menviond. 
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.
