also, no doubt, by the direction of the wind at the time. Our data are at present too scanty to lay down with precision the minutiæ of their lines of flight, but another year's observations will probably greatly assist us. The same rules, as to time of day or night at which birds strike the lantern, holds upon the west coast which also obtain on the east, and the same remarks as to weather also hold good. The above remarks upon the direction of the flights upon our west coast may prove of value in a comparison with Mr. Cordeaux's notes upon the direction of the flights at the Galloper Bank. We are aware here that birds pass overland on migration, crossing Scotland between the Firths of Clyde and Forth, as they have been heard on calm nights crying as they passed over from W. to E., or from points N. of W. to points S. of E.; and day-flights have often been observed passing here from N.N.W. towards S.S.E., or from N.W. to S.W. I would instance here Bramblings, _Fringilla montifringilia_, natives of Northern Europe. (See Gray's 'Birds of the West of Scotland,' p. 137. The "column" of Bramblings there described as on migration were not "proceeding in a north-easterly direction," however, as stated by Mr. Gray, but were coming from a north-westerly direction, and were proceeding in a south-easterly direction.) * * * * * Transcriber Note Minor typos were corrected.
