Subftance, ^nd the Medulla of another, and that lodged 
in proper Cells, with a Root diftind from them both ; 
( ^ ). Befides, fays he, Nature fometimes produces 
monftrous and defective things. An Animal fometimes 
wants a Limb, a Tree is without (bme principal Bran- 
ches, a Fruit may want fome of its chiefeft parts, Yet 
ftill we may obferve that Nature fupplies and covers 
that defeft with a Skin, or Bark, or Rind, fo that it ne- 
ver appears torn ofF or rent to the naked Eye, as it 
would, if it were torn off by a Hand, or cut off with a 
Knife. This is Natures conftant courfe; w^hich evi- 
dently (h^s that the Lufus Natura, ( as thefe are cr- 
roneoufly called ) were never produced in the Earth ; 
fince all the bruifes and fradur^s, which they have met 
with,are apparent without any difguize to hide them, as 
Nature always employs to hide the Effefts of her own 
irregular ProducSions. 
He argues likewife from the Beds in which they arc 
found, wherein. Gravel, Clay, Teeth, Bones, Shells 
of all forts lay confufed in one Mafs. As alfo from the 
impreflions which they leave behind them in the Marl, 
even to the minuteft Lines and Craks in the Tooth, 
which appear exaftly in both, like an Impreflion upon 
Wax, and the engraving on the Seal which made it. 
The Apophyfis alfo, or Proceffes in the Glojfopetne de- 
monftrate their Original, were there nothing elfe ; fince 
they exaftly anfwer to thole in Sharks Teeth, whereby 
every Tooth is inferred into his Neighbour in the living 
Animal,- with thofe parts porous, and thofe fpongious 
that are fo in the Tooth of the Filh. Nay, wtereas 
Sharks Teeth are raortifled into one another in fuch a 
manner, that a man may eafily tell which belongs to 
which fide, which lie near the Throat, which near the 
Snout, which lie to the Right, and which to the Left. 
And whereas in a Sharks Jaw, the Teeth on the Left 
Side will not fit on the Right, nor thc^ above ferve
