art III. And Stones lif\e them. 257 
The SHARKS TOOTH. Glofopetra : fo cali'd , for 
that thefe Stones were fabled by fome to be the Tongues of 
Serpents, in the Ifle Malta or Melita, turn d into Stones 
ever fince St. Paul Preached there. But the Englijh Name, 
is much more anfwerable to the fhape. Which yet is va- 
rious, as well as the fize and colour 3 as alh-colour'd or 
black, long or broad, {trait or crooked, with the edges 
toothed or plain. Of the brown, {trait, indented and 
broader fort here are feveral very great ones. One, three 
inches broad 3 and four, long: with the exerted part, 
fmooth 3 the Root, rough. Every way, in (hape, fo like 
the Tooth of a Shark, that one Tooth cannot be liker to 
another. Yet if it be fuch, then by comparing thofe in 
the Head of a Shark, with This, That to which This be- 
long'd, to bear a jufl porportion, muft have been about 
fix and thirty feet in length. 
A GLOSSOPETRA, growing to aftony Bed. ? Tis of 
a lightifh colour : and was brought as is fuppofed, from 
Melita. 
ANOTHER , of a leffer fort. The Root of this is 
rough, as of the reft. But not expanded with the exerted 
part, as is ufual, but of a globular Figure. 
Thefe Stones are diffoluble with any Acid. Whereby it 
appears, That ( befides fuch Metallick Principles they are 
fometimes tinctur d with ) they abound with an Alkalizate- 
Salt. They are found not only in Melita, but in Germany, 
and many other places. Figur'd by Aldrovandu5 (a) and by (a) Matkm 
others. Metallic - 
DRAGONS TEETH. Given by Sir Phil. Skippon. 
Glofopetrae Claviculares. So I call them , becaufe they 
feem to be of the fame kind 5 and are long and {lender, 
fomewhat like a fmall Nail 3 and much more like a Tongue 
(fc. of fome fmall Bird) than any of the former. 
The GOATS-HORN. Tephrites Boetij 3 from its aflien 
colour. Selenites Cardani^ from its almoft Semilunar 
Figure. Inwardly, 'tis of a blewifh Grey. Outwardly* 
mixed with oblique and white ftreaks. Of a bended figure, 
yet with one end thicker than the other, not unlike a Goats 
Hom-j whence I have taken leave fot the Englijh Name. 
Broken at both ends, yet above ? a foot long, and two 
inches and \ where broadeft. The Belly or inward Ambit,
