 local) showing only the larger stars, when bright, shifting streamers began to appear 8 or 10 

 above the horizon ESE., then shooting up as a band through Leo and Taurus, then forming 

 several broad sinuous bauds in Leo, which rose to the zenith and formed an elongated corona 

 rendered indistinct by the twilight. At 2 a. in. there was a sinuous band (brightness 1 to 2) in 

 the ESE.. running up from Virgo into Bootes and Corona Borealis, and a broad hazy zone across 

 the x.enith from the twilight in the NNW. to the moonlight in the ESE., occupying Andromeda, 

 Cassiopeia, Perseus, Auriga, Camelopardalis, Ursa Minor, Ursa Major, and Leo. At 2.15 to 2.20 

 the zone was in essentially the same position, but shifting and changing from a zone to a twisted 

 band and back again, and moving slowly westward. At 3 a. in. an area of curtains (brightness 2) 

 rapidly developed from the NW., consisting of three or four shifting rows from Andromeda to 

 Hydra and from near the SW. horizon to Auriga, slightly tinged with the usual colors. At :>.!"> 

 to 3.20 there was a band of curtains from Libra through Hercules, a Lyra-, and Cygni, waving 

 from E. to X. and developing a large patch in Lyra and a few bands in the place of zone at 2 a. 

 in., which quickly developed a small faint corona and all rapidly faded. At 4 a. in. there was a 

 similar baud of curtains in the XE., partly obscured by clouds. At 4.15 to 4.20 there appeared 

 faint bands and streamers in the N. and NE. mixed with patches of cloud. Clouds interfered with 

 observation at the next two hours, but it had cleared at 7.15 to 7.20, and showed a quiet band 

 (brightness to 1) from Aquila through Pegasus, Andromeda, and Perseus from E. to NNW. At 

 9.17 there was a corona of long slender rays centering towards the zenith, waving slightly. The 

 needles began to be agitated at the first sign of the aurora, and the disturbance continued all night, 

 reaching its maximum at 3 p. m. 



March 23, 1883, 1 a. m. to 8.20 a. m. At 1 a. m., while the daylight was still very bright, so that 

 only the largest stars were visible, there was a white, sinuous, shifting streak in the E. near Arcturns. 

 At 1.15 a. in. there was one arched baud in the E. through Arc-turns and Virgo, and a twisted, 

 shifting band across the zenith from SE. to NW., soon fading, and extensive patches developing 

 in the E. At 2 a. m. a rather narrow, shifting zone, waving slowly, crossed the zenith from the 

 ESE. in Virgo to NW. in Andromeda through Bootes, Canes Venatici, Ursa Major, Ursa Minor, 

 Cepheiis, Cassiopeia, Perseus, and Andromeda, and two arched sinuous bauds in the XE., the upper 

 through Corona Borealis, Hercules, a Lyra?, and a Cygni, and the lower near the horizon. At 2.15 

 to 2.20 the zone had shifted W. nearly to a Auriga 1 , fading gradually, while a new zone developed 

 in the former place and bands in the E. shifted. Clouds interfered with the next three observa- 

 tions, and, though the sky then cleared, no more aurora was seen till 8.15 to S.20, when a yellowish 

 band (brightness 1), waving slowly, ran through Leo, Leo Minor, Ursa Major, Canes Venatiei, Draco, 

 and Cygims, sending up a few rapidly vibrating streamers in Cygnus. The magnets were dis- 

 turbed from 7 a. m. to 2 p. m., the maximum disturbance being at <S a. m. 



March 24, 1883, 1.45 a. m. to 3.15 a. m. The twilight was still bright at 1.45, but a well-defined 

 arch (brightness 1) was observed running through Bootes (just above ), Corona IJorealis, Hercules, 

 Draco, and a Cygui, and rising rapidly. At 2 a. m. a broad yellowish band (brightness 1 to 2), 

 fringed on the upper edge, with ill-defined streamers, lay in the ZS'E.. passing through Canes 

 Venatici, the tail of the Great Bear, Draco, and Cygnus to the twilight in the NW. This had 

 risen at 2.15 a. m. to form a narrow zone (brightness 1) from the KSK. to NW. through Canes 

 Venatiei, Ursa Major, Ursa Minor, Draco, Cepheiis and Cassiopeia to Andromeda. Three or four 

 ill-defined rolling curtains developed quickly from the E. towards the N., with rapid, quivering 

 motion propagated in the same direction through Koiites, Corona I'.orealis. Hercules and Lyra, 

 reaching a brightness of 2 to ." in Bootes in the E., with a bright display of green, yellow, and rose 

 in the usual order, quickly quieting down and growing paler, while the' zone widened in both direc- 

 tions to about, twice its usual width and growing hazy, and then developing a waving motion on 

 the western edge. At the next observation the clouds already so obscured the aurora that trices
