But whether the Report heard near Lervis were of that 
Explofion right over Devonjhire, or rather of that latter 
and much greater at the Extinction over Br/tany, I (hall 
not undertake to determine, till we have fome further 
Accounts from France, whence hitherto we have only 
had, that at Paris the Time of the Appearance was at 
17 Minutes pad Eight. 
It remains to attempt fomething towards a Solution 
of the uncommon P/j^nowena of this Meteor; and by 
comparing them with things more familiar to us, to fliew 
at lead how they might podibly be efFe(ded. And firft 
the unufual and continu’d Heats of the lad Summer in 
thefe Parts of the WorkJ, may well be fuppos’d to have 
excited an extraordinary Quantity of Vapour of all forts; 
of which the aqueous and mod others, foon condens’d 
by Cold, and wanting a certain Degree of Specifick Gra- 
vity in the Air to buoy them up, aicend but to a fmall 
Height, and are quickly returned in Rain, Dews, 
whereas the inflammable fulphureous Vapours, by an in- 
nate Levity, have a fort of f^is centrifuga, and not only 
have no need of the Air to fupport them, but being agi- 
tated by Heat, will afeend in Facuo BoHeano, and fublime 
to the top of the Receiver, when mod other Fumes fall 
indantly down, and lie like Water at the bottom ; the 
Experiment whereof was flrd fliewn me by the Reverend 
Mr. Whitefide ^x.Oxford, and was very lately made before 
thz Royal Society. By this we may comprehend how the 
matter of the Meteor might have been raifed from a large 
Tra(d of the Earth’s Surface, and afeend far above the re- 
puted Limits of the Atmofvhere being difengaged 
from all other Particles, by that principle of Nature that 
congregates Homogenia vifible in fo many Indances, its 
Atoms
