The Southern Quarter was fiird with continual 
Flalhings of Light. Thefe followed one. another very 
quick, and were propagated upwards from the afore- 
mentioned Arch w’ith great Swiftnefs, each of them 
leaving in Tome parts of the Space it pilVd through, a 
faint, and very tranfient Whitenefs, w'hich prefently 
vanilli’d, and was quickly renew’d, ufually in the ve- 
ry fame Track, by the next fucceeding Flafli. Yet 
none of thofe Tracks were in any degree diredl and u- 
niform ; but all very irregular and broken. 
The Central Figure fometimes difappear’d for a 
while, and then returned again. Whether it always re- 
tained the fame Situation with refped: to our Horizon, 
I cannot depend on the Exadtnefs of my Obfervations 
enough to determine. They were as follow. 
About half an hour paft Eight, the Center, as well as 
I could judge by my Eye, was very near a Star of the 
fifth Magnitude, placed by Hevelius at the End of the 
Lizard^s Tail, whofe prefent Right Afcenfion is about 
331^, and Deck 36^ and an half N. At Nine, it 
was at the Northern Point of an Ifofceies Triangle^ 
whofe Bafe was a Line joyning the Star in Pegajus 
Shoulder, call’d Scheat^ and thebrighteft of thofe in 
his Knee ; the Perpendicular from the Center being 
in proportion to the Bafe, about as 3 to ^. At 9b. 15^ 
the Triangle made between that and the two forementi- 
on’d Stars was become Right-angled at Scheaty the 
Diftance being not much alter’d. At Ten, it was di- 
redly betw'een the Zenith and Andromeda’s Head, 
at a Diftance from this Star not fenfibly different 
from what it had kept from the Northermofl of the 
Two forememioned.
