Aug. 10th, Isle of May, all rock birds left, except a few Kittiwakes; heavy westerly gale on 9th. Oct. 23rd, Pentland Skerries, flocks flying E.; strong W., showers. Nov. 2nd, Pentland Skerries, large flocks, noon, flying S.E. from S.W. (?). Nov. 27th, Isle of May, abundant in sea along with Gulls; "Garvies," _i.e._, _Culpea sprattus_, abundant (J. A. H. B.). Dec. 20th, Isle of May, large numbers; fresh W., haze. Dec. 27th, Isle of May, large numbers; S.W., haze. This completes our data of Guillemots and Razorbills, to which the whole of the above records refer for 1883; and I think it shows pretty plainly the life-history of these birds, at least in some important particulars. A wider appreciation can be arrived at if similar tabular returns come in from other salient points of observation, such as Isle of May, Bell Rock, and one or two stations on the east coast; and Cape Wrath, Butt of Lewis, Monach Isles, and Barra Head on the west coast; and also for summer migrations, especially such stations as Island Ghlais, Skerryvore, and Dhuheartach, and others on the inner line of stations of the west coast. These data are minutely detailed here this year, because I have felt more at liberty to do so, owing to the light returns of most of our land birds, thus having more space than usual at command. Further remarks, should such occur to us, will appear in the "General Observations," which I withhold till the close of the West Coast Report. EAST COAST OF ENGLAND. Printed schedules and letters of instruction were forwarded to thirty-seven lighthouses and light-vessels on the East Coast of England, and two stations in the Channel Islands, and returns have been received from twenty-five, against thirty in 1882. Independent reports have also been received from Heligoland, and certain land stations along the East Coast, namely, Seaton-Carew, Redcar, Flamborough, Spurn, North-East Lincolnshire, Wells (on the Norfolk coast), Northrepps, Great Yarmouth, and the coast of Essex. Making altogether a total of thirty-five reporting stations, against thirty-seven in 1882.
