round so as to point towards 335°. The next in brilliancy came from bearing 

 76°, which also crossed the zenith, but did not unite with the other beam. 

 There were two other streams of light running in the same direction. The 

 needle had moved 48' eastward since nine, and in a contrary way to the course 

 it usually followed when vertical arches crossed the zenith, at about 279° or 

 324°. 



January 25th, 9h. p. m. a brilliant curve, terminations 324° and 76°, eleva- 

 tion about 50°. Several beams jutted from this curve, pointing towards the 

 horizon. At llh., a beam rose at 279°, passed over the zenith to 99°, then ran 

 horizontally, and formed an irregular band from 99° to 171° ; the portion of light 

 at 99° was stratified by intervening layers of clouds. 



27th. A beam elevated about 13°, at midnight, whilst snow was falling. 



28th, 9h. p. m. An arch from 99° to 349°. At llh. the coruscation gene- 

 rally diffused over the south and eastern parts of the sky, which seemed to 

 have proceeded from a slender beam bearing 99°, from whence a flash darted 

 to the zenith, which instantly dilated into a broad mass of light. At midnight, 

 an elevated arch, and a low convexed stream, extended from 99° to 200°. A 

 beam at 94° pointing towards the zenith. Needle stationary. 



29th. At ll|h., a broad arch across the zenith from 99° to 257°, and an 

 horizontal fringed belt from 99° towards the east, at a low elevation. At 

 midnight, the S.E. portion of the sky was occupied by a dense mass of light, 

 which resembled an open fan, branching upwards ; a stream shot from the 

 eastern part of it, and proceeded in an arch to 290°, the centre being elevated 

 70°. Several patches in the zenith parallel to this arch. In two minutes after- 

 wards the fan disappeared, and a brilliant curved stream darted forth at 110°, 

 and shot to the westward ; its centre bore 133° elevated 25°. 



30th. An arch across the zenith from 302° to 121°, but the extremities did 

 not approach either horizon by 20°. 



31st. At 9h. p. m., two horizontal bands of light extended from 99° to 

 212°, the lowest being elevated 8°. The S.E. end was wavy, and it appeared 

 as if several beams had been twisted together. There was also a beam at 

 302°, directed towards the zenith, At midnight, an elliptical arch proceeded 

 from 99° to 279° by the south and westward, at a low elevation. Several 

 streams issued from this band between 279° and 245°, each pointing towards
