A. Harvie Brown, Mr. John Cordeaux, Mr. W. Eagle Clarke, Mr. R. M. Barrington, and Mr. A. G. More, for the purpose of obtaining (with the consent of the Master and Elder Brethren of the Trinity House, the Commissioners of Northern Lights, and the Commissioners of Irish Lights) observations on the Migration of Birds at Lighthouses and Lightships, and of reporting on the same at Aberdeen in 1885. Mr. Cordeaux to be the Secretary.
The returns relating to Scotland have been arranged by Mr. J. A. Harvie Brown; for the East Coast of England, by Mr. Cordeaux; for the West Coast of England, by Mr. W. Eagle Clarke; and those for the Coasts of Ireland, by Mr. R. M. Barrington, Mr. A. G. More, and Mr. Eagle Clarke.
Having obtained an additional grant from the British Association, we venture this year to add a new feature to our Report in the form of a sketch-map, showing all the stations in red. We have done this at the intelligent request of several of our reporters; and the map has been executed for us by Messrs. Macfarlane & Erskine, of St. James' Square, Edinburgh.
