of a Rainbow, of one vivid, bright, yellowifli Colour, 
and all under was, as it were, a very dark Cloud ,* tho’ 
by viewing it with a Telefcope, we could difcern the 
minuteft 6tars : So that the Darknefs only proceeded 
from the greatnefs of the Light juft above it. From 
this, as from the former, arofe very lucid, bright Co- 
lumns on all parts of it. No Corufcations appear’d un- 
der it. Its greateft Height might be 20 or 30 Degrees. 
Some of the' Columns feem’d to radiate even to the 
Zenith from this Arch. 
About 9, this lucid Arch vanifh’d infenfibly, with 
moft of the luminous Radit^ or Columns ; but, as it 
were, a very bright Crepufculum (till remained all along 
the Northern Horizon^ and feveral very bright Coruf- 
cations would feem to be ftiot out of the pure Sky : 
This, more efpecially, was obferv’d in the N .E. A- 
bout I r , I obferved feveral Corufcations ftill breaking 
forth, and here and there a luminous Column; and fe- 
veral little bright Clouds feem’d irregularly fcatter’d up 
and down the Hemifphere, which ftill retain’d their 
darting and quivering Motion. The Northern Crepuf- 
cuium remain’d as bright as ever, and fo continued till 
paft Two in the Morning. 
There were but very few, and thofe very fmall Clouds 
to be obferved during the whole time of thisPhaHomenony 
and the Air was clear ; yet all around, and between the 
lucid Columns, whenever, or in what part foever 
they appear’d, the Air would feem very thick and ha- 
zy ; tho* immediately upon the difappearing of thofe 
gleaming Lights, the Sky would in the fame Place ap- 
pear very clear and ferene. Nay, even thro’ fome of 
the very Columns we could plainly difcern the Stars. 
Some Gentlemen thought they faw the bright Stars of 
the Swan thro’ the Corona it felf.
