from the Motion into which the Waters were put during 
the Deluge n being well known that if Egg.(heIJs, 
Straws, Pebbles, Shells andfeveral other diffimilar fub- 
fiances be put into a great quantity of Water, and this 
Water be afterwards moved violently and irregularly, 
thofe diffimilar Bodys will after a great many Shocks 
and impediments, upon the fetthng of the Water, fub- 
fide according to their Figure pretty nearly together, 
and confequencly will be thrown into great Heaps, fome 
here, fome there, according to that determination 
which the rolling of the Waters ^ive them. 
The Places where thefe fevcral Subftances are thus 
feparately found, are as he thinks invincible Arguments 
in proof of his Opinion. The Soil of Malta is Marl, 
which is a natural Balfam for the Glojfopetra, that 
otherwife would have been fbon wafted in loofe Sand. 
Befides, Malta lies low if compared with the Mountains 
of Sicily^ fo that 'tis no wonder that Sharks Teeth, 
which are heavy Bodys, Ihould firft fubfide, and confe- 
quently be found there in great quantities, whereas with 
all his diligence, Signior SciSa could never find but five 
upon the Sicilian Mountains, and thofe cxtreamly thin, 
and without any Ofleous Matter within them, but filled 
with a light and fubtije Matter tho' he does not que- 
ftion but in time he may be able to find, at the foot of 
thefe Hills, fome Glojfopetra which may equal thofe of 
Malta. 
And this, , according to him, is the Reafon why in 
Malta it lelf, the Echini and Echinits are chiefly found 
upon the ftrand and above ground in view, all round 
the Ifland ; for they are both lighter than the Glejjopt» 
tr£, and by reafon of their Figure would more eafily 
float and be buoyed up upon the Water, whereas the 
Gloffopetr^ being both fpecifically heavier, and of a 
clofer contexture of parts, funk deeper into the Earth.
