Tuefday fan. 23,' the Air at Wells was clear 
^ and ferene during the greateff Part of the Day, 
with a frefh Breeze of Wind at S. $. E. which termi- 
nated in an Evening extremely remarkable for Ap- 
pearances in the Heavens of an uncommon Aurora 
BoreaHs.

Foot of an Arch, which formed an Angle of about 
ten Degrees with the N. E. Part of the Horizon. 
This Arch (hot out pointed Streams like Pyramids,, 
of a fiery red Colour, which generally afeended 
within a few Degrees of the Zenith, then vaniftied, 
and were immediately fucceedcd by others, from the 
N. E. where the principal Magazine feemtd to be.

with fudden Flashings and Dartings 5 but towards 
the Weft the Appearances feldom altered.

fiery Arch, which fiill kept fomewhat of that Form, 
tho’ frequently interrupted by fhooting Flafhcs from 
the N. E. 
At 4,0 Minutes paft 5, there appeared fuddcnly in 
the N. E. an elliptical Corona , of an amazing Bright- 
nefs, elevated about 9 Degrees above the Horizon, 
and having its longeft Diameter parallel thereto. 
There fnot up perpendicularly from this Streams rc-
