( 4*4 ) 
which was no other than a Segment of a Ring or £one 
of the Sphere, intercepted between two parallel lefler 
Circles, cut off likevvife by the Horizon ; or, if you 
pleafe, the Segment of a very broad Iris, but of one 
uniform Colour ; viz. a Flame-colour inclining to yellow, 
the Center thereof being about forty Degrees below die 
Horizon. And above this there were fee n fome Rudi- 
ments of a much larger Segment, with an Interval of dark 
Sky between, but this was fo exceeding faint and uncer- 
tain that I could make no proper eftimate thereof* 
I was very defirous to have (een how this Phenomenon 
would end, and attended it till near Three in the Mor-

our Aurora, had not follow’d him, but ended in that very 
Point where he then was ; whereas in the true North, 
which the Sun had longpaft, the Light remained unchan- 
ged and in its full Luftre. 
Hitherto I have endeavoured by Words to reprefent 
what I faw, but being fenfible how infufficient fuch a 
verbal Defcription of a thing (o extraordinary and un- 
known may be to mod Readers, I have thought fit to 
annex a Figure exhibiting that particular Appearance of 
the two Lamina, which I faw at London between the 
Hours of Ten and Eleven: more efpecially, becaufe Ido 
not find, among the many Relations I have feen, any
