General Observations. The state of this month has been generally wet 

 and boisterous, with a mild air for the season, excepting a few days. In 

 the afternoon and night of the 6th, a very heavy gale blew here, first from 

 the South, then from South-west, during which time one inch and a quarter 

 of rain fell; but the quantity was much greater in some of the Northern 

 districts, where damage to a considerable amount is said to have been done 

 by the rush of water from the hills, and the consequent inundation of the 

 adjacent lands. 



Early in the morning of the 9th a little ice appeared on the ground, 

 being the first time this autumn. In the morning of the 15th a parhelion 

 appeared on the east side of the sun : and at 2 P.M. on the 17th, a faint 

 anthelion was observed on a light cloud opposite to, and nearly of the 

 same altitude as the sun; it was perfectly circular, colourless, and brighter 

 than the cloud in which it appeared, and of the same size as the sun's ap- 

 parent disc. 



The mean temperature of the atmosphere this month is four-fifths of 



within our 

 solar and 



three lunar halo?, ten meteors, three rainbows, four aurorae boreales, and 

 thirteen gales of wind, or days on which they have prevailed, namely, one 

 from the North, three from the East, one from the South-east, two from 

 the South, and six from the South-west.
