But if there were no other Argument, the fituation 
of ih^ Gloppetrs in their Beds from whence they are 
dug, puts their Original out of controverfie : Midling 
ones here, fmall ones there, great ones in a third place, 
without any fort of order and regularity : Some with 
their Roots uppermoft , others direftly downwards, 
others acrofs : vaft numbers broken, every one with a 
different Inclination, all plainly proving how they firft 
Game thither, fince had they grown there at firft, their 
Roots would have been all downwards, unlels we (hould 
frame to our felvesa different Notion to the Produftion 
of Glofopetr£, from any thing elfe in Nature that is ge- 
nerated and increafed from fome one fixt Seminal Prin- 
ciple. And, befides, were there fuch a feminal Prin- 
ciple, 'tis not likely that it fliould be common to G/offi- 
fetr^e and Shells too | and yet Shells of all forts, and 
in all pofitions are very often found in the Clay amongft . 
thefe GloJJopetra. 
It is obje<3:ed however, that the Gloffopetrs may be 
eafily taken out of their Beds by their Sides, or at the 
Point J whereas at the Bafe they adhere very clofely, 
from which there often comes forth a plain Root, which 
is oftentimes longer than the Glcffbpetra it felf. This, 
fays Signior Scilla is a plain proof of rny Aflertion. 
For that Root is not made by Nature to fack out [ or 
rather convey'] any nutritiv^ juyce into the Glojjbpetra^ 
from the Mud, hm from the Jaw of the Shark where 
it originally grew. It was no wonder therefore that 
their -Tides and point, which are naturally very hard 
and fmooth, did not ftick fo firmly to the Mud, or 
Stone wherein 'twas lodged ; but it would have been 
a wonder if the Root, which in all Sharks Teeth is ve^ 
ry fpongious and very porous, had not been filled with 
liquid Mud, that would eafiiy have fixed it in its Bed^^ 
when it once began to harden.: And accordingly he
