The records received during the autumn of 1909, although 

 not quite so voluminous as those of the previous year, have 

 oflPered considerable difficulties in the way of condensation. 

 The Committee quite realized that their reports were be- 

 coming too cumbersome and perhaps too detailed. A 

 considerable effort has therefore been made to shorten the 

 sections dealing with that period, and wherever the facts 

 were sufficiently full to indicate definite movements these 

 have been shortly outlined and the detailed records largely 

 omitted. In a number of species this has been found to 

 be impossible, and the Committee have therefore thought it 

 best to adhere to the plan already adopted and publish the 

 records themselves. 



Our thanks are due to Miss Rintoul and Miss Baxter 

 for their notes from the Isle of May, to Staff-Surgeon K. H. 

 Jones, R.N., for some valuable observations made at sea on 

 PI.M.S. ' Dido,' to the Master and Elder Brethren of Trinity 

 House and to all observers and lightkeepers for their kind 

 co-operation, without which our investigations would be 

 impossible. Notes from other published sources have also 

 been carefully read and their facts incorporated with 

 our own.
