PREFACE. 



The following Keport contains a summary of investigations 

 of the Committee re-appointed by the British Association for 

 the Advancement of Science, at Montreal, Canada, in 1884, to 

 consist of Professor Newton, Mr. J. A. Harvie Brown, Mr. John 

 Cordeaux, Mr. W. Eagle Clarke, Mr. K. 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 Com- 

 missioners 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. B. 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 

 Keport 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.
