Nov. 10th, Sumburgh Head, eight flying S., 12 noon; fresh N. breeze, hail. The annual regularity with which the Solan Geese pass and repass through the Pentland Firth and various other points of observation cannot, we think, fail to develop, by the statistics accumulated, some curious facts in migration. We are thus careful to record these with some minuteness of detail. A late schedule from Sumburgh Head has--"Two on 16th, Sumburgh Head. Eighteen Gannets flying S.W., 12 noon; strong W., showers." Ardeidæ.--We do not think it will be so easy, in regard to Herons, to arrive at laws regulating their flights; but, in case of development, will on this occasion tabulate their records, though we have not done so before. _Spring._ March 29th, Pentland Skerries, one flying N., 3 p.m.: S. gale, rain.
