opportunity of observing that meteor for upwards of two hundred different 

 nights. 



November 1 3th, in the evening the sky was covered by a stratum of fleecy 

 clouds, their forms generally orbicular and texture rare. They were separated 

 from each other by intervals of clear-blue sky of various extent, but in some 



in contact. The Aurora was observed to move along these clouds, 



points came in contact, 

 strongly illuminating their faces next to the earth, and very seldom passing 

 across the blue sky, but spreading from cloud to cloud by their points of con- 

 tact, sometimes slowly, more often with considerable rapidity. The light was 

 generally brightest in the centre of the cloud, and it often originated simulta- 

 neously in various parts of the heavens, more or less distant from each other. 

 At some moments the whole sky was illuminated. No distinct beams were 

 seen, and the light had uniformly a grayish colour, with a light tinge of yel- 

 low. Thermometer at noon + 1 0°, in the evening + 8 



Nov. 24th. A bright moonlight evening, cloudless sky, with a light breeze 

 from the W.N.W. An arch-formed Aurora, extending from S.E. to N. W. This 

 arch was composed of several disunited portions of arches, every succeeding 

 one having a higher commencement and termination than that which preceded 

 it, reckoning from the horizon to the zenith. Their altitude near the centre of 

 the imperfect arch which they formed by their arrangement was from 40° 

 to 60°. One of these portions presented a smooth edge inferiorly, or towards 

 the south, but its northern border was fringed with long falcate pointed 

 rays, whose bases appeared to twist together to form the southern edge. 

 It had a striking resemblance to a shoot of the moss called dicranum scopa- 



rium majus. 



Nov. 26th. Ther. at noon, — 13°, in the evening, —25°. Sky cloudless, and 

 of a pretty deep blue. An Aurora appeared in the early part of the night, 

 having a general direction from N.W. to E.S.E. It consisted of several 

 concentric but irregular arches, all of which, without changing their position, 

 occasionally assumed the falcate form observed on the 24th. The upper- 

 most arch nearly reached the zenith. The smaller stars became invisible 

 when the brighter parts of the Aurora passed over them. Although the air 

 appeared perfectly clear during the time the Aurora was visible, yet there 

 was a fall of a very small snow. Its particles were so minute as to be
