EXPEDITION TO POINT MAL'ROW, ALASKA. 419 



NE., which may have, been auroral, but the brilliant moonlight rendered it impossible to lie surf, 

 of this. At .'> ;i. in. a rather broad, striated, liax.y band (brightness 1 ) crossed the zenith from near 

 horizon ESE. in Hydra to Viilpeenla XXW., at an altitude of about 15, passing through Cancel', 

 Lynx, Camelopardalis. ( 'assiopcia, Cepheus, Lacerla, and Cygnus (close to;). This \va.s in the 

 same position at .'!.15, but was narrower, paler, and very sinuous and twisted. At the, next two 

 hours there were no traces of aurora, but at <!.15 there \vere t\vo bands of yellowish-green streamers, 

 starting from IJoiites, one going X. through Corona Borealis. Draco, and Cygnus, and the other S. 

 through Ctfma Berenices, Leo Minor, and Gemini. The streamers vibrated rapidly from W. to K. 

 (brightness 1 to 2). At 7.15 there were faint traces in the S. At 8.15 two quiet bands (brightness 

 to 1) ran through Bootes, Canes Venatici, Ursa Major, Auriga, and Perseus. The aurora then 

 died away to mere traces, which were wholly gone at 11 a. m., reappearing at noon, and gradually 

 developing, first iuto sinuous streaks across the zenith with streamers in the SE., and then into a 

 corona (brightness to 1) centering in Ursa Minor. This was replaced by a narrow sinuous band 

 at 1.1.7 running through Cyguus, Ursa Major, and Leo Minor. Traces of this band were still 

 visible at 1.50, when the daylight was quite bright. A magnetic disturbance commenced at ,'i a. in. 

 and was still going on at 3 p. in. (10 a. in. local time), with o:ie maximum at li a. m. and one at 2 

 p. in., both with very high eastern declination and very low horizontal force. 



January 25 and 20, 1.883, 10.15 p. m. to 1.17 i>. in. As soon as it grew dark enough for an aurora 

 to be visible a faint arch appeared in the XE. with its extremities NN\V. and KSE-, passing through 

 Bootes, Canes Venatici, Ursa Major, Leo Minor. Lynx, and Gemini. The altitude of the crown was 

 about 50. At 11.15 this had developed into a zone, with its extremities X T W. and SE. The north- 

 ern edge ran through Hercules, Draco, Ursa Major, Lynx, Gemini, and Orion, and the southern 

 edge through Orion, Auriga. Perseus, Cassiopeia, Cepheus, Lyra, and Hercules (brightness 1 to 2). 

 At 12.15 a. in. waving bands of curtains ran through Serpcns, Cygnus, Lacerta, Andromeda, Tau- 

 rus, and Orion, and. there was also a hazy patch in Orion, Gemini, Cancer, and Leo. At 1 a. m. a 

 broad, hazy, sinuous band, festooned and breaking into streamers and irregular patches in the 

 XX YV.. ran from the ESE. in Monoceros to the NNYV. in Hercules, through Cauis Minor, Gemini, 

 Lynx, Auriga, Camelopardalis, Ursa Major, Ursa Minor, and Draco. There was also a luminous 

 patch in Taurus continued by an imperfect baud through ( 'assiopcia, and a band in the E. from Leo 

 through Leo Minor and Canes Venatici into Bootes (brightness 1). At 1.15-this was broken and 

 mostly faded, except the band in the E. and streamers in the XX\Y. There was nothing left at 2 

 a. in. except a few streamers in the N. and XX T W. in Lyra and Hercules, which had developed at 

 2.15 into four slightly diverging, sinuous bands (brightness to 1), all ending in the clouds in the 

 SE. One passed through Draco and Ursa Major, one through Draco and Ursa Minor, one fading 

 near Cygni, through Cephens, Cassiopeia, and Camelopardalis, and one through Lacerta and 

 Cassiopeia. At 3 there were broken streamers in the X". and NW., and one pale band across the 

 western horizon through Pegasus, Aries. Taurus, and Orion. This was replaced at 3.15 by three 

 bands, narrow and rather hazy, starting between Yulpecula and Pegasus NNW. to XW., the upper 

 through Cygnus, Cassiopeia, Camelopardalis, Auriga, and Gemini, growing very pale; the next 

 through Pegasus, Andromeda, Perseus, ft Aurig;e into Gemini, and the lowest through Pegasus, 

 Triangulum, Aries, Taurus, and Orion, all fading in the moonlight in the SE. (brightness to 1). 

 At 4 a. in. there was a regular narrow arch (brightness 2) tinged with green and rose in the W., 

 with an altitude of about 25, running from the ESE. in Hydra (just below ) to the NW. just below 

 f Pcgasi, through Monoceros, Orion (<5), the lower part of Taurus, Cetus (), and Pisces. At 4.15 

 it was lower, passing through the nebula in Orion, and paler (1 to 2) with a band above it (bright- 

 ness 1) through Canis Minor, Gemini (/), Taurus, and Aries (). The needles were agitated. At 

 5.15 a yellowish band, waving very slowly, ran from Cygnus through Draco, Ursa Minor, Ursa 

 Major, Leo Minor, and Leo to Hydra, while a second band commenced from Cygnus through Lyra, 

 Corona Borcalis, Canes Venatici, Bootes, and Cotua Berenices to Leo (brightness 1). At G.15 a 

 quiet band (brightness to 1) extended from Cassiopeia through Cygnus, Hercules, and Serpens 

 to Boutes. Nothing remained at 7.15 except traces in the SW. At 8.15 a faint, quiet band ran 

 from Taurus through Auriga, Gemini, and Leo. At 9.17 there was a small patch in the SE. and a 

 narrow, white, and quiet band running thence through Bootes, Coma Berenices, and Leo, and also 

 a 1,'Hght patch in the SW. in Gemini (brightness 1 to 2). At 10.15 a broad, irregular, white, qriet
