bout 19 Degrees to the North of om Zenith ^ defcended 
as low as the Tail of Urja Major which it left a little 
to the South. It continu’d thus for fome Minutes 
and then gradually vanilh’d. Wind North, about

March 3^. The Appearances this Night were fo ex- 
traordinary, that they wou’d require a long defcrip- 
tion: But I lhall chiefly take Notice of fuch particulars 
as differ’d from thofe of 0 £loher 8. 
I ’ That inftead of one Lunainous Arch in the North, 
here were two and fometimes three one above ano- 
ther. They were diffint^ enough from each other in 
their upper parts, but blended together towards the 
Hortzoiti which they generally cut about N. E. and AT. 
W, but fometimes varied confiderably from thefe 
Points. 
The fame Obfervation may be apply’d to the 
height Sy for they were alfo variable 5 and in parti- 
cular, the inner edge of the lowermoft Arch v;as at 
fometimes about 6 Degrees above the Horizon others, 
confiderably more or lefs. 
I fuppofe this extroardinary Appearance was owing 
to feveral diftin< 3 : Colledions of Luminous Vapours, 
which were either at different heights from the Earth, 
or different diftances from the Eye. 
zdlyy Several of the more permanent Streams were 
bent, at times, into irregular Arches of different Cur- 
vatures and Pofitions. 
Some of them held pretty near the fame lhape 
till they vanilli’d, others went off mofl; com- 
monly in Tangents to fome part of the former Curves. 
The Flalhing Streams from the Eaft fometimes 
met with thofe from the iVefl, and fo form’d continu’d 
Arches, of a pale colour, which quickly broke and va- 
nifli’d. No colouring follow’d upon the mixture of thefe 
Streams^
