quam Terra noftra, p. 4 66. Now if the Moon Be mor© 
folid than the Emhas^to 5, why may we not reason- 
ably fuppofe the Moon, being a fmall Body and a Secon- 
dary Planet, to be folid Earth, Water, and Stone, and 
ebis Globe to confift of the fame Materials, only four 
ninths thereof to be Cavity, within and between the 
internal Spheres : which I would render not improbable. 
Tothofethat iliall enquire of what ufe thefe included 
Globes can be, it muft be allowed, that they can be of 
very little fervice to the Inhabitants of this outward 
World, nor can the Sun be ferviceable to them, either 
with his Light or Ffeat. Butfince it is now taken for 
granted that the Earth is one of the Planets, and they 
all are with reafon fuppofed Habitable, though we are 
notable to define by what fort of Animals $ and fince 
we fee all the partsof the Creation abound with Ani- 
mate Beings* as the Air with Birds and Flies, the Water 
with the numerous varieties of Fifh, and the very Earth 
with Reptiles of fo many forts ; all whofe ways of living 
would be to us incredible did not daily Experience teach; 
us. Why then ftiould we think it ftrange that the pro* 
digiousMafs of Matter, whereof this Globe does con- 
fift, fhoUld be capable of fome other improvement than 
barely to ferve to fupport its Surface? Why may not 
we rather fuppofe that the exceeding fmall quantity of 
folid Matter in refpeft of the fluid Ether, isfodifpofed 
by the Almighty Wifdom as to yield as great a Surface 
for the, ufe of living Creatures as can confift with the 
conveniency and fecurity of the whole. We ourfelves, in 
Cities where we are prefled for room, commonly build 
many-Stories one over the other, and thereby accom- 
modate a much greater multitude of Inhabitants. 
But {till it will be faid that without Light there can be 
no living, and therefore all this apparatus of our inward 
Globes muft be ufelefs : to this I anfwer that there are 
many ways of producing Light which we are wholly 
ignorant
