398 Meteorological Observations for September 1830. 



General Observations.— This month has been generally wet and windy, 

 but most of the rain fell in the night-time. From the 8th to the 24th it 

 rained every clay more or less, frequently accompanied with boisterous 

 equinoctial gales. 



Hoar frost appeared in the grass-fields early in the mornings of the 22nd 

 and 26th. At 11 A.M. on the 28th, a greater number of swallows con- 

 gregated over Gosport and its neighbouihood than has been seen for 

 many years; perhaps there were not less than 1200 or 1500 at one view, 

 flying leisurely in all directions, and intermixing with each other : after . 

 making a few circular flights for ten minutes, they rose three or four hun- 

 dred feet in height, and then departed in a southerly direction, except a 

 few young ones ; making their stay here twenty-three weeks and two days. 



The mean temperature of the external air this month is four degrees 

 under the mean of September for many years past. 



The atmospheric and meteoric phaenomena that have come within our 

 observation this month, are one anthelion, one parhelion, twenty-six me- 

 teors, four rainbows, three aurora? boreales, lightning in the evening of the 

 20th, and thirteen gales of wind, cr days on which they have prevailed, 

 namely, one from the South, eight from the South-west, two from the 

 West, and two from the North-west.
