Year: 1859

Having been questioned about, and asked to account
for the phenomenon which was observed last night
that OF red and lurid light ovespreadng the armament
but which did not witness, have taken pains to
obtain from some who it, information to its first
appearance diffusion and termination ltis stated that
about l O'Clock, A. M, red light observed in a
nothwesterly direction, apparently at an elevation of
about 80 degrees and although the night cloudy,
some stars were visible through the glare. The light
gradually spread, without intensity diminution, and
by 2h. pom. the whole armament was Illuminated
After this it gradually assumed purple and then pink
hue during the continuance of which small objects were
visible as if shone upon by the moon. This light became
gradually fainter, and did not entirely disappear till
dispelled by the rays Of the rising sum-


Such phenomena are not uncommon in high northern
aitudes especially in cold weather. but they rarely
witnessed far south this at any season OF the year.
AS to their many theories have been suggested,
but it is now generally conceded that they owe their
origin to electricity and the exhibition of last night
conceive to have been grand display of electrical light
widely dffused aurora BoreaHs.


The following short extract from Lardner, think is

The Aurora Boz calls is luminous phenomena which ap

hemisphere. TIE term Aurora Poaris would be more
proper designation.


This phenomenon consists of luminous rays of various
coors issuing every direction but cOnverCing the
