Storm Petrel.—At Butt of Lewis in July, August, and September, an occasional bird at the glass, always at night, always in hazy or rainy weather, generally "haze and rain" together; wind in three out of four instances S.W., and once on July 3rd, W.N.W., stormy. At Rhu Stoir a good many were observed "not on passage" between 17th and 20th Aug. between 6 p.m. and 10 p.m., wind N. to E., light, haze and rain; and at Rhinns of Islay on Sept. 17th, one struck at 2 a.m., wind S., light, and haze.

Sea-fowl.—The following notes upon sea-fowl as observed at several stations—notably at Cape Wrath—will, we think, prove interesting:—At Cape Wrath, Mr. M'Gill reports all the sea-fowl as deserting their breeding-haunts there on Aug. 16th, and both old and young flying westwards. He roughly estimated the numbers which passed within his ken as follows:—300 to 400 Guillemots, 800 to 900 Razorbills, 800 to 900 Puffins, 100 Scarts, and 300 Sea-gulls. This was performed in an east wind, during hazy or rainy weather (see also under Solan Goose), and all left Cape Wrath in one day and about the same time, viz., 10 a.m. The Gulls passed continuously between 9 a.m. and 3 p.m. Notes from other stations can hardly be considered as applying to anything but local daily migration in search of food, as is constantly witnessed at any rock-bird station on the coast; thus, at Rhu Stoir large numbers passed towards S.W., and are specially noted on June 12th to 15th; also at Kyleakin, a large flock passed southward at 2 p.m., wind S.E. When at the Shiant Isles this summer, at the end of June, I witnessed a regular departure of thousands of Puffins to their feeding-grounds in the Little Minch, about 9 to 10 a.m.

Sea Gulls.—At Cape Wrath on Aug. 10th, three hundred passed west between 9 a.m. and 3 p.m.; wind E., haze, and rain. "Sea Gulls bred at the station, and all left on the same day, both young and old. The migration goes all to the west."

Kittiwake, Rissa tridactyla.—At Skervuile on May 31st, two at noon flying north; calm, clear.

Tern.—At Dhuheartach, six seen on the evening of Aug. 27th, wind S., cloudy; and four at the same station on the morning of Sept. 4th.

Birds unknown.—At Portpatrick on July 12th, a flock of small birds passed overhead at 8.30 a.m., wind S.S.E., fresh, and rainy; and on Oct. 13th a flock passed inland at 4.20 p.m., wind S.W., and rain; on Nov. 13th "a flock of birds not known" passed inland, wind E. by N., and clear. At Pladda on Aug. 20th, one Snipe, species not known, at 4 a.m., wind S.E., strong, and haze; and another on Nov. 15th. At Skervuile, on Nov. 14th, a number from 10 p.m. to 2 a.m., wind variable, light, and haze; and others on Oct. 7th at Skervuile; "many killed and fell into the sea."

Red-breasted Merganser.—At Corsewall, on July 20th, a "strange Duck" (since identified as a Red-breasted Merganser) was killed at glass at 2 a.m.; wind E., light, with haze.

Solan Goose, Sula bassana.—At Cape Wrath and other stations upon our coasts, an extraordinary annual migration of Solan Geese is witnessed. Mr. M'Gill has reported to me specially on that of 1879, and kept as accurate a record as possible of the numbers which he estimated to pass westward. He writes as follows:—"The number of Solan Geese that migrate past Cape Wrath is beyond anyone's power to number, but I have come as near to it as possible. The first half of July the flocks were composed of old birds, and the rest of the time they were mixed old and young." Mr. M'Gill then gives the following list of Solan Geese seen passing west on fifteen days, between 14th July and 9th August, which I reproduce here:—

July14th.600 to 700. 9 a.m. to 8 p.m.Wind E. Clear.
"15th.200. 9 a.m. to 8 p.m. " E. Haze.
"16th. 40 to 90.12 noon to 7 p.m. " E. Haze.
"22nd.200 to 400.10 a.m. to 7 p.m. " N.-N.E. Fog, rain.
"24th.100 to 200. 8 a.m. to 6 p.m. " S.W. Clear.
"26th.300 to 400.11 a.m. to 7 p.m. " S.W. Haze.
"28th. 90 to 100. 7 a.m. to 8 p.m. " S.W. Haze, rain.
"31st. 60 to 80.10 a.m. to 5 p.m. " S. Haze, showers.
Aug.1st.100 to 300. 8 a.m. to 6 p.m. " W. Haze, rain.
"3rd.300 to 400. 9 a.m. to 6 p.m. " E. Clear.
"4th. 60 to 70.10 a.m. to 7 p.m. " E. Fog, clear.
"5th. 20 to 30. 8 a.m. to 5 p.m. " N.E. Fog, rain.
"7th. 40 to 50. 9 a.m. to 6 p.m. " N. Fog, rain.
"8th. 20 to 40. 8 a.m. to 7 p.m. " N. Fog, rain.
"9th. 20. 9 a.m. to 5 p.m. " N. Haze.

Thus it will be seen that from 2150 to 3080 were estimated to pass westward within view of Cape Wrath, between July 14th and August 9th, during fifteen days occupied on migration. All which were observed passed during the day—say between 7 a.m. and 10 p.m.—and apparently in all winds and weather. From the Butt of Lewis Mr. Edgar supplies the general information that the Solan Geese pass the station, arriving first in May, and leaving in the latter end of October, but giving no particulars as to direction of flight. At Mull of Galloway Solan Geese are reported as passing, on July 19th, in flocks. Mr. N. B. Morrison reports as follows:—"Saw them flying past to W.S.W. in wedge-shaped flocks as if on a passage, or changing locality." This was during the forenoon; wind S., light, and haze. "At 1 p.m. it began to rain, and continued for twenty-four hours; rain guage at 9 a.m. of 20th, 1·72 inches. On 21st, 22nd, 23rd, and 24th, very strong breeze, and showers; wind W.N.W. to S.W." Again at same station (Mull of Galloway) flocks continued passing all day; wind S.E., fresh, fog, and rain, flying in same direction. On 8th and 9th, wind S., gale; 10th, wind W., strong. In a later note Mr. M'Gill believes "that the Solan Geese strike the land first at Cape Wrath," and that the Geese which pass it are from Suliskerry.
