neither one or the other remember what Night it 
happened 5 and being uncertain of the particular 
Night, is the Reafon I omitted it in the Account : 
But fince it happens, that I am treating of thefe Tha- 
nomenons , which may have fome Relation to the 
Earthquake, and proceed from the fame firft Caufe, I 
imagine it muft have been the fame Night, though per- 
haps not. However it may have been, I have related to 
you a true Expofition of all things as they really were y 
and there is now a way opened for Philofophical 
Obfervations and Inquiries. As for me, I fhould be 
of Opinion, that it is a Colle&ion of thofe Vapours 
and Exhalations proceeding from the Fermentation 
or Lighting of thofe Particles of Matter, which occa- 
lioned the Earthquake ; but fhould be obliged to you 
for your Sentiments on it, having a great Regard to 
your Opinion. I remain as above.
