mass oi' curtains in the NYV. in Delphinus and Vulpecuhi. At 3.15 it was more broken and still 

 paler with sonic bright patches in the NE. At -1 a. in. the eastern end of the /one stretched from" 



in the E. to Canis Minor in the ESE., but the whole converged to Scrpens in the !N~CS"W. The 

 upper hand passed through Leo and Gemini and below Cassiopeia, while the remaining four or 

 live bands filled the whole southern arid western sky nearly to the horizon. They were all sinn- 



, brightness 2 to 3) and the upper band was beginning to develop coronal bunds, which vibrated 

 rapidly, north of the magnetic meridian S. to N., south of it N. to S. The bands were more broken 

 and paler at 4.15 and a large corona was rapidly developing. At a. m. rive bands covered nearly 

 the whole sky, some made up of streamers in rapid motion, others motionless (brightness 1 to 2)1 

 At 7 there were three bauds, yellowish, and brightness 2 to 3, one from Cancer through Ursa Major 

 and Draco to Cygnus, one from Gemini to Cygnus across the zenith, and the third from Canis 

 Minor to Andromeda tlirougli Perseus. At 8 a. m. there was a faint arch from the S. to SW. from 

 Leo to Orion and a few patches in the E. (brightness to 1). At 9.15 there was a white and quiet 

 semi-corona in the S. from E. to W., and from 10 above the horizon to the zenith (brightness 1 to 

 2). At 10.15 there was very little change in the character of the aurora except that it had ap- 

 proached nearer the zenith on the southern side, and a broad band with streamers extended along 

 the southern horizon from E. to W. There were also a few streamers on the northern side forming 

 a nearly complete corona. At 11.15 the baud along the horizon had disappeared and the main body 

 of the aurora shifted north of the zenith, and grown paler (1). There was slight motion. At 12.15 p! 

 m. there was a white, quiet arch on the southern horizon from the SSE. to the W. with but 10' alti- 

 tude, a band from the SE. through Bootes, Canes Venatici, near Ursa Major, tlirougli Auriga to 

 Taurus, and streamers in the SE. and W. The whole was white and quiescent (brightness to 1)! 

 At 1 p. m. the band on the southern horizon was unchanged and there was a complete corona! 

 At 2 p. m. there were faint traces in Cassiopeia and Auriga, but at about 2.30, although the sky- 

 was quite bright, streaks fully 1 in brightness llashcd up in the !NW. and crossed the zenith to the 

 SE. while streaks and streamers forming almost a corona in very rapid motion, both circling and 

 vibrating appeared and disappeared round the. zenith with great rapidity. A magnetic disturb- 

 ance of considerable violence commenced about 10 p. m. December 15, and lasted till 5 p. m. De-

Decanlx'i- 17, 1882, 3.15 a. m. to 11.15 a. m.A faint streak or two was noticeable in the S. and 

 SIC. at 12.15 and 2 a. m., but there was no definite aurora till 3.15, when there was a pale band of 

 streamers (brightness to 1) in the E. from Regulus to Procyon and a still paler band from Pro';' 

 cyon in the ESE. to Hercules in the NNW. passing through I'rsa Minor close to the zenith. At 4 

 a. m. there was a partial corona (brightness 1) centering near the zenith extending in azimuth" 

 from Auriga in ESE. to Cygnus in CS'XW. with its streamers longest, about 50 degrees long, in the 

 constellation l.'rsa Major. There was also a fan-shaped bunch of secondary streamers in Leo in 

 the 1C. 1 1 had faded at 4.15, except the lower streamers in the E. and 2s T E. At 5 there were merely 

 traces in the SW. and S. and no more was seen till 8 a. m., when there were two faint bands from 

 Andromeda to < >rion, and the other from Taurus through Oriou to Hydra (brightness to 1 ). From 

 !>.15 (.) 1 1.15 there were merely faint traces of aurora through the. clouds which obscured the hor- 

 izon. The magnetic needles were comparatively quiet all night.

 streamers, motionless, in the XE.. passing tlirougli Gemini, Lynx, Leo Minor, Canes Venatici. and 

 <'oma IJerenices. Between 11 and 12 pale shifting streamers developed above this arch, Imt were
