General Observalions.— The weather this month has been mostly fine, 

 with occasional siiowers, which were often accompanied by heavy gales of 

 wind. On tiie ;$rd instant, the last flight of swallows departed for a warmer 

 climate. In the evenings of the 6th and loth lunar halos appeared, and 

 were followed by rain and wind. 



On the mornings of the 7th, 8th, and 9th, ice appeared on the ground 

 the first time this autumn, and the days were unusually cold : the maxi- 

 mum tempcratrue of the 8th did not exceed 48 degrees, and light showers 

 of snow were seen at Horndean, and in other parts of Hampshire. The 

 mean temperature of this day and night is about equal to the mean of 

 Christmas-day and night for tlie last fourteen years ! 



On the 2jth a fine coloured pariielion appeared on the northern side of 

 the sun, with a faint solar halo. In the afternoon of the 30th two winds 

 crossed each other from North and West, when the clouds between them 

 showed an electrical appearance, and lightning emanated from them in the 

 evening. 



7'he incan temperature of the external air this month, is two and a quar- 

 ter degrees less than the mean of October for many years past. 



The atmospheric and meteoric piioenomena that have come within our 

 observations this month, arc, one parhelion, one solar and two lunar halos, 

 five meteors, and thirteen gales of wind, or days on which they have pre- 

 vailed ; namely, three from the North, one from the North-east, six from 

 the South-west, one from the West, and two from the North-west.
