a nearly horizontal beam oflight, a depressed arch was formed to the northward 

 of the zenith, from various parts of which pencils of light shot up directly towards 

 the south, and rising 40° or 50°. Portions of two smaller and concentric arches 

 were occasionally seen under the other. 



At 9h. the Aurora continued to exhibit modifications of the appearances 

 above-described. 



At midnight, an irregular mass of light, having a spirally twisted form, rose 

 in the horizon in the N. W. b. N. to the height of 60° apparently perpendicularly. 

 Then turning to the northward, it continued its course horizontally across the sky ; 

 and, lastly, bent suddenly and obliquely to terminate in the S. E. horizon. 



Rapid pretty loud. No 

 mist from it. 



A few cirro-strati. Thin 

 mist from the rapid. 



No mist from the rapid, 

 which was pretty quiet.

N. b. W. and E.b. S, From its north end several rays rose to the height of 

 10° or 12°, having a direction to the south. 



At 9h. a zone oflight, rising from the horizon, in the N. E., swept round the 

 sky to the eastward and southward, with a gradual ascent, until it bore S. W., 

 and had an elevation of 35° ; from thence it gradually descended and finally 

 terminated in the N. W. b.N. point of the horizon. Near the eastern horizon, 

 this zone was continuous, but towards the south it was composed of thin and 

 parallel layers. 



At midnight, the Aurora cohered the sky in fleecy masses, having the. same
