Is it not thus that fire is amaffed and makes the greateft 
part of the fubftance of combuftible bodies ? 
Perhaps when this globe was firft formed and its origi- 
nal particles took their place at certain diftances from the 
centre in proportion to their greater or lefs gravity, the 
fluid fire attracted towards that centre might in yreat part 
be obliged, as lighteft, to take place above the reft, and 
thus form the {phere of fire above fuppofed; which would 
afterwards be continually diminifhing by the fubftance it 
afforded to organized bodies, and the quantity reftored to 
it again by the burning or other feparating of the parts 
of thofe bodies ? 
Is not the natural heat of animals thus produced by fe- 
parating in digeftion the parts of food, and fetting their 
fire at liberty? 
Is it not this fphere of fire which kindles the wandering 
elobes that fometimes pafs through it in our courfe round 
the fun, have their furface kindled by it, and burft when 
their included air is greatly rarefied by the heat on their 
burning furface ? 
May it not have been from fuch confiderations that the 
ancient philofophers fuppofed a {phere of fire to exilt above 
the air of our atmofphere?
