PREFACE. 



This Eeport contains a summary of the investigations of a 

 Committee reappointed by the British Association for the 

 Advancement of Science, at Manchester, in 1887, to consist of 

 Professor Newton, Mr J. A. Harvie-Brown, Mr John Cordeaux, 

 Mr W. Eagle Clarke, Mr E. 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) obser- 

 vations on the Migration of Birds at Lighthouses and Light- 

 ships, and of reporting on the same at Bath in 1888. 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 and Mr A. G. More. 



This is the ninth, and final, report issued, and the Committee 

 have much pleasure in stating that one of their number, Mr 

 William Eagle Clarke, of the Museum of Science and Art 

 in Edinburgh, has undertaken the laborious task of reducing 

 the mass of facts collected, from an examination de novo of the 

 whole of the schedules sent in, so as to bring out the general 

 results of their inquiry, both statistically and otherwise, on 

 strictly scientific lines, and in as condensed and clear a method 

 as possible.
