Aumra Borealis. 



At 8*30 p.m., there was no appearance of Aurora noticed here* 

 the sky was then cloudy, covered by Cumulus et Cumulo Stratus 

 clouds to the extent of 8,10th. 



At 9 p.m„ which is one of the usual hours for observation at 

 this place, the appearances were thus recorded : " Splendid Aurora 

 Borealis extending nearly over the whole horizon with the excep- 

 tion of a small space in the S> & S. W., sky covered over with 

 patches and streamers of Auroral light, — varying in colour from a 

 pale yellow to deep orange and violet or crimson, giving the 

 appearance of moon-light and nearly as light and bright as when 

 the moon is at its full and giving rise t> nearly the same colour." 

 The horizontal and vertical movements were frequent and very 

 rapid and it seemed as though the Cumulus and Cumulo stratus 

 clouds were lighted up with the Aurora. The exact moment of 

 its appearance here was not observed, but it was between 8-30 and 

 9 p.m., this appearance lasted, with modifications, till nearly sun- 

 rise. 



There was also a fine display on the following night (Monday) 

 the 29th, but nothing to be compared in brilliancy to the Aurora 

 of the previous evening. The sky was on this occasion cloud- 

 less, a few streamers were occasionally seen tinted with a pale violet 

 colour. 



The 26th day was mild and pleasant, mean Temperature 69°4, 

 at 8 p.m., distant lightning was observed in the E., but its pre- 

 sence did not affect the Electometers. Volta's Electrometer No. 

 1 indicated scarcely 2 degrees, positive. 



The 27th day was partly clouded. Mean Temperature 64°7, 

 shewing a decrease in Temperature, and a falling Barometer. 



The 28th day (Sunday) was for the most part cloudy, the fol- 

 lowing is an extract from the register,
