4. I find by fome of my Papers that during 
the Meteor of the Mercury flood at 30.x,- 
fo that the two Meteors agree, as in many other 
particulars, fo in the following, viz* That the Air 
was calm, The Wind North-wefterly and the Mercury 
high. 
I fhall only add, that luminous Vapours in the Air 
arc much more common than they are generally taken 
to be ; for the Nights are very often lighter when 
the Sky is over-caft, than in the brightell Star-light, 
tho’ the Crepufculum be quite gone off and there be 
no Moon. 
I am, fe’e.
