ON THE SCOTTISH ZOOLOGICAL STATION. 233- 
year, birds follow the same lines, or great highways, of migration, when 
approaching or leaving our shores. The constancy of these periodical 
phenomena is suggestive of some settled law or principle governing the 
movement. It is clearly evident, from the facts already at our disposal, 
that there are two distinct migrations going forward at the same time, one- 
the ordinary flow in the spring and ebb in the autumn across the whole. 
of Europe. A great migratory wave moves to and from the nesting- 
quarters of the birds, in the coldest part of their range, north-east in the 
spring and south-west in the autumn. Quite independent of this there 
is a continual stream of immigrants, week by week and month by month, 
to the eastern shores of these islands, coming directly across Europe from 
E. to W., or more commonly four points south of east to north of west, 
and the reverse in the spring. These immigrants are mainly composed 
of those common and well-known species which annually make these 
islands their winter quarters, and, as a rule, take the place of our summer 
birds. They come in one broad stream, but denser on some special lines 
or highways than others. Cutting the line of ordinary migration at 
nearly right angles, one flank brushes the Orkney and Shetland Isles, 
pouring through the Pentland Firth, even touching the distant Faroes ; 
the southern wing crosses the Channel Islands, shaping its course in a 
north-westerly direction to the English coast. : 
In conclusion your Committee would take this opportunity of once 
more expressing their best thanks to the Master and Brethren of the 
Trinity House, the Commissioners of Northern Lights, and the Commis- 
sioners of Irish Lights, for their ready co-operation and assistance, through 
their officers and men, in the inquiry. 
Your Committee respectfully request their reappointment, and trust 
that the Association will enable them to continue the collection of facts. 
Report of the Committee, consisting of Dr. PyE-Smitu, Professor 
M. Foster, Professor HuxLey, Dr. CARPENTER, Dr. Gwyn JEF-- 
FREYS, Professor Ray LanKESTER, Professor ALLMAN, and Mr. 
Percy SLapDEN (Secretary), appointed for the purpose of aiding 
in the maintenance of the Scottish Zoological Station. 
Durine the past year the station has been removed from Oban to the east 
coast of Scotland, where it is again erected upon the northern shore ot 
the Moray Frith, within a few miles of the site which it occupied in 
1880-1 when the researches on the locomotor system of echinodermata 
were conducted. 
Owing to an unfortunate oversight on the part of Dr. M. Foster the 
grant of 40/., which had been awarded to the station by the British Asso- 
ciation, was not applied for in due time, and in consequence when it was 
applied for was found to have lapsed. The researches which were con- 
templated when the station was again erected on the shore of the Moray 
Frith were for this and for other reasons unavoidably postponed.. 
Hence the only work which has been carried on at the station during the
