58 THE SCOTTISH NATURALIST 



rush were of the continental form, but Thrushes and 

 Redbreasts from the same rush were British birds. Hedge- 

 accentors procured in autumn proved to be of the British 

 race ; in fact, all those got on the island by us have belonged 

 to this form (with the exception of one doubtful bird), thus 

 showing that our British Hedge-accentor is a partial 

 migrant. Most of the birds passed on immediately after 

 this ; but some Greenfinches, Chaffinches, and Linnets lingered 

 for a time, and a Water-rail killed itself on the wire and was 

 sent us on 8th November. On 15th November two Black- 

 caps ( $ $ ) were killed at the lantern, and there were Snow 

 Buntings on the island about this date. 



We wish to express our most cordial thanks to the 

 Commissioners of Northern Lights for their continued 

 kindness in granting us permission to work on the island. 

 We are deeply grateful to them for all they have done 

 for us. To all our good friends on the island we owe 

 a debt of gratitude which we can never repay. Our special 

 thanks are due to Mr and Mrs Baigrie for all they 

 did for us while we were with them, and for birds and 

 notes sent after our departure. Mr and Mrs Ross, as 

 always, were most kind and hospitable, and we thank them 

 most heartily, and also Mr and Mrs Wilson, and all our 

 other friends for their many kindnesses. Mr William Evans 

 has kindly given us permission to use his ornithological 

 notes, which are incorporated in this article, and we thank 

 him very warmly for his generosity. We must also thank 

 Dr Hartert for his help in determining some of the racial 

 forms for us.
