which I observed on the 24th of June of the present year, I con- 
‘that a notice of such an occurrence cannot but be interesting to 
ction. 
fhe phenomenon, on this occasion, presented the usual appear- 
aces, although the coruscations were not of that vivid and brilliant 
ter which they have frequently presented during the darker 
ights of the winter and spring of the present year. The streamers 
bright, but more steady than are sometimes observed, and 
asionally rose to the height of 50° above the northern ho- 
m. No arch was observed, but the usual darkness, which I should 
tate to designate as cloud, was early observed in the northern 
izon, though this was at no time so weil defined as I have on many 
asions seen it. The aurora was first observed at 115 46™ p.m., 
and continued until 12" 20™, the streamers extended over a space of 
20°, the magnetic north being its middle point. 
_ This is not by any means a solitary instance of the occurrence of 
Aurora during the last summer. 
- On the 19th May I observed a very fine Aurora. On this occasion, 
very beautiful bands of arches, radiating from magnetic west, 
ended nearly to the opposite horizon. One, when first observed, 
extended directly over head, was very thin and not very perceptible 
in the east; the other, a much narrower band, consisting of three or 
four arches, not defined with the same distinctness throughout, rose to 
the height of 40°, and extended to the opposite horizon. The arches 
had a slow motion from north to south (magnetic), and in their course 
passed over several stars, and also the planet Jupiter, and the bril- 
liancy of these was but slightly dimmed by the interposition of the 
arch. No streamers were seen on this occasion, nor did I note the 
appearance of the usual darkness in the northern horizon. The arches 
were observed from 9" 40™ till 10° 15". The moon was near the full, 
which rendered the phenomenon less striking than it otherwise would 
have been. 
- On the 1st July, at 12" 30™, I observed indications of an Aurora 
about the magnetic north. I noticed a faint coloured light above two, 
“not very well defined, bands of darkness. At 1" 10™ I was called up 
_ to witness a vivid and brilliant display of coruscations. These rose, 
to the height of 30° or 40°, over an extent of more than 20°, from the 
dark cloud usually attending the Aurora. Although they were most 
brilliant when first observed, beams of light were visible for a quarter 
of an hour; but after this, if any coruscations occurred, they were 
invisible, in consequence of the increasing light from the sun. No 
arches were, on this occasion, observed. On the 2nd July there were 
sided appearances of Aurora, accompanied by streamers; but these 
vere much fainter than on the preceding night; and, again, on the 
th there were indications of Aurora, though of a less decided cha- 
acter. is . 
On the 25th August there was a very splendid display of Aurora, 
ich continued from 10" 25™ until 10° 51™. The streams of light 
v ere extremely brilliant, and rose to a considerable height, passing,
