( ) 
Between nine and ten I was agreeably furpriz’d with 
a kind of Corufeation, or Flalliing, that fliew’d it felf 
between twenty and fixty Degrees from the Ze/iith, iii 
the South or South by Weft 5 and which from four or 
five, fometimes from more places at once, darted with 
a Velocity not much inferior to that of Lightning ; and 
by interfering with each other produc’d a beautiful Tre- 
mour or Undulation in that ['ubiWo. which I can- 
not better illuflrate, than by comparing it to the Beams 
of the Sun, refletfted on a Ceiling from the Surfaces of 
two or three Bafons of Water ; Thefe Waves of Light 
were only vifble at the inftant of Corufeation, and 
were of a pale whicifli Colour, fomewhat refembling the 
flaflies produced by the violent agitation of Quickfiver 
in an Exhiufted Receiver; but fo ftrong that a Gentle- 
man who about that time w^as in a Room by himfelf, 
without a Candle, afTur d me he took it for common 
Lightning : Thus it continued inceftantly for more 
chan an Hour, during which time feveral lucid Areas^ 
like little Clouds, difeover’d themfdves in the pure 
Sky, and after they had continu’d about fve or fix 
fecond Minutes, as near as 1 could guefs, would in- 
ftantaneoufly difappear ,• moft of them pretty much.re- 
fembl’d a very thin white Smoke or Vapour illumina- 
ted by the Full Moon. 
About three quarters paft Ten, this Vapour was al- 
moft fpent, or by a brisk Gale at South by Weft difpers’d 
and driven to the Northward; at which time, be- 
tween the Weft and North, a vaft body of it, like a 
very bright Flame-colour’d Crcfufculum, feem’d to be 
fix’d : From this Bafts feveral Beams or StrU of {hmmg 
matter were at uncertain intervals, emitted ; and tho’ it 
was not fo feniibie to tbe Eaftward of the North, yes; 
feveral mighty Pillars wefe alio cjjtfted from thence; 
One, which if 1 rmftake not, arofs dired^Iy under
