, Mr. IIey’s Account of j 
in the country. I firft obferved two or three columns of 
aurora borealis (hooting upwards in the north ; and m a fhort 
time after I faw a complete arch, like thofe already defcribed, 
though fomewhat different in its pofition. It arofe between 
the E. and N. and N.E. points, pafled obliquely to the fouth 
below Ardurus, and defcended in the weft through Orion, 
having almoft the fame direction through that conftellation 
'which the equator has. It was the moft luminous in Orion, 
and juft below Ardurus. A fmall black cloud crofl'ed it in the 
eaft, and hid a part of it, equal to the breadth of the cloud, 
from view. Its light was the moft faint about the vertex of 
the arch. Its moft denfe parts were continually varying in the 
mtenfity of their light. The larger ftars were vifible through 
its denfeft parts. It varied its pofition, which 1 could heft ob- 
ferve where it pafi'ed through Orion ; for there it moved not 
lefs than io degrees towards the fouthern part of that confte - 
lation. It continued vifible about half an hour ; and, although 
I paid as ftrid attention to the changes which pafled m it as 
my fituation would admit, yet I obferved nothing which could 
be called a {hooting or quick corufcation. There was a fteady 
northern light all the evening, or at leaft till the arch had 
difappeared. 
The moft grand fpecimen of this phenomenon which 
I have feen appeared on the 1 2th of April, betwixt nine 
and ten in the evening. I had obferved, for above half 
an hour, as 1 was travelling, a light in the weftern part 
of the atmofphere ; but as this lay in the direction of fome 
iron-works then before me, which often {hoot out a flame 
illuminating the air to a confiderable diftance, I did not 
pay much attention to the appearance. But having pafled the 
thundery, and ftill feeing the light before me, I locked through
