The following short notes on weather are compiled from the 'Times' Register for 1881, and checked by my own schedules:--A sudden change of temperature at the beginning of August, colder by about two degrees than July. Rainfall excessive over all Scotland, except northern half where it was less than average; cold and wet all August, about six degrees colder than corresponding period of 1880. Prevailing wind W., seldom veering to E., until Aug. 23rd; thereafter in Scotland prevailing E. and N.E.; on Aug. 31st N. winds prevailed, N.E., and continued till about Sept. 6th; thereafter W. and N.W. till 16th; then S. and S.E. till 21st; from 22nd to 24th E.; 24th to 30th S. to W.; Oct. 1st to 10th S.; 10th to 13th strong W.; 14th gale from E., and continued E. and S.E. to end of month. S.E. to S. strong winds and gales, or light from Nov. 1st to 11th; S.W. strong and a gale 15th and 16th; frost on 17th; 22nd S. to S.W. and W., heavy gales in N. and W. Unsettled, with frequent changes of wind and weather, many W. gales till end of month, and till Dec. 8th. N. and E. on both coasts from Dec. 9th to 12th, S. on 13th, and S. and W. on 14th; S. and W. till 20th, when E.; and W.N.W. on 21st. Prevailing W. and S.W. till end of month. _Notes._--Prevailing winds at the time of the rush of _Falconidæ_ were W., veering from S.W. to N.W. in Aug.; after 23rd E.; on and after Aug. 31st till Sept. 6th N. At XIV., on Aug. 19th, a Sparrowhawk was seen sitting on the ground, and almost daily for some time after. The nearest breeding-place I know of is at Tongue, N. Sutherland; wind at the time was light S., and weather clear. No doubt it is difficult to discriminate often between local and general migrations of Hawks by our data; thus at XIV. also, on Aug. 23rd and 24th, a Sparrowhawk was seen flying south on the former date, and N.E. on the latter; on the former date the wind was light S., on the latter N.E.; this would therefore appear like a local migration. The only addition to the list of stations is Fair Isle, No. 7 b. In all spring records the numbers of stations begin at the most southerly, or with the higher numbers. In all autumn records the numbers of stations begin at the most northerly, or with the lower numbers. The maximum station, or station sending most returns of the species, is indicated when thought necessary.
