34 RECORD OF AURORAL PHENOMENA. 



over to the horizon at 279°. A very slender faint arch remained from 9° to 1S9°. The needle 

 moved a little westward. 



6th. At 9h., masses of light of irregular breadth fringed the upper part of a range of clouds 

 extending from 99° to 212°. At midnight, a waving low stream from 99° to 212°, of dense 

 light, the motion rapid, going towards the latter bearing. Motion of the needle westward. 



7th. At 9h. p. m., an arch stretching from 2*19° to 110°; motion of the needle westward. At 

 lOh. 30m., a very irregular arch from 99° to 234°. The interior motion darted rapidly in 

 opposite directions, and the red, purple, and violet colors were exhibited. Numerous slender 

 beams, in which there was a quick lateral motion, shot from this arch; some of them were pro- 

 jected to the zenith. The arch separated at 121°, and the western portion immediately rushed 

 towards the north, preserving the same elevation. At this instant, the wind changed from the 

 north to the opposite direction, south. At midnight, a horizontal band appeared from 99° to 

 234°, and several beams to the southward. The needle moved eastward 27' between nine and 

 midnight. 



8th. At llh. 10m. p. m., various streams appeared, stratifying a dense mass of clouds. In two 

 parts of this coruscation, the motion darted from 144° and 324° towards the zenith; in another, 

 from 76° to the horizon at 144°. The needle had moved westward 2° 19' since nine. At mid- 

 night, a beam rose at bearing 65°, and darted to an elevation of 30°. Nearly at the same 

 instant, another beam issued from 9° and joined this, and then an arch was formed terminating 

 in these bearings. Several other masses of light were seen to the eastward. The needle had 

 moved eastward 1° 55' since the last observation, lleavy dark clouds spread over a large 

 portion of the sky. 



11th. At midnight, a faint gleam of Aurora appeared through a very dense atmosphere, and when 

 there was a halo round the moon. 



13th. Atmosphere hazy; no Aurora or stars were visible, yet there was a motion of the needle 7° 

 to the westward between nine and midnight. 



14th. A faint arch from 313° to 133° at midnight. 



15th. At 9h., several brilliant beams bearing 54°, in which there was much lateral motion and a 

 variety of colors. An arch crossed the zenith from 313° to 133°. Needle moved westward 9'. 

 At midnight, an arch across the zenith from 290° to 110°. Another from 65° to 313°, the 

 motion passing rapidly from the latter to the former horizon. Needle moved a little more 

 westward. 



18th. At midnight, a faint patch bore 144°. 



19th. At midnight, streams of a dense pale yellow light, at a low elevation, nearly parallel to the 

 horizon, and extending from 99° to 200°. These were stationary for some hours; dark clouds 

 lay between them. 



20th. Whilst daylight remained, the Aurora was perceived fringing the upper part of a mass of 

 dense cloud, in shape like the festoons of a curtain. It extended from 99° to 200°. At mid- 

 night, a waving arch of low elevation from 76° to 212°. Needle had moved 45° westward 

 since nine. 



21st. At 7h. p. m., some streams of cloud which resembled the Aurora in shape aud color, crossed 

 the zenith; but when the daylight disappeared, no Aurora was visible. 



23d. At lOh. 30m. p. m., Aurora first appeared in an arch from 279° to 189°, elevation 12°. 

 Needle moved westward 1° 11'. 



27th. At midnight, aurora appeared through the haze in two low arches from 99° to 189°. 



29th. Aurora beamed through the haze in low streams of faint yellow color. 



30th. At llh. 40m., some patches of Aurora at 144°, elevated 20°. No motion perceptible in 

 the needle. 



May 1st. The coruscations were very agitated and brilliant between llh. and midnight, but they 

 did not produce any change in the needle. 



3d. At midnight, Aurora proceeded from a mass of dense cloud bearing 99°; passed near the 

 zenith to 257°. The attenuated beams of which this arch was composed had a quick lateral 

 motion. Little change in the needle. Daylight in the eastern part of the sky. 



5th. A faint stream proceeded from 144° to an elevation of 45". Needle moved westward.
