PREFACE. IX 



Captain Scots Fusilier Guards, for several valuable notes on the 

 birds of Islay, Ross-shire, and the Outer Hebrides; and to Henry 

 D. Graham, Esq., for his admirable account of the birds of lona 

 and Mull. To Captain H. W. Feilden, 4th King's Own Royal 

 Regiment, and J. A. Harvie Brown, Esq. of Dunipace, I am also 

 indebted for many observations of great interest made by them- 

 selves in the islands of North Uist, South Uist, and Barra, in the 

 summer of 1870, as well as for other acts of kindness at a time 

 when their assistance was of most value. Mr Harvie Brown has 

 besides favoured me with a perusal of his numerous journals written 

 in various districts of Scotland, especially the coasts of Stirling and 

 Sutherland; and I have been at the same time under obligations 

 of a like nature to another friend Edward R. Alston, Esq. who 

 has furnished me with lists from the Upper Ward of Lanarkshire. 

 Dr J. A. Smith, of Edinburgh, has in the kindest manner allowed 

 me the use of his important notes on many rare birds which have 

 occurred for the most part in the eastern and south-eastern 

 counties; and Professor Dickie, of Aberdeen University, has also 

 taken a kindly interest in procuring me information from those 

 lying to the north. From another resident in Aberdeen Mr W. 

 C. Angus I have received very great assistance in forming an 

 estimate of the numbers of migratory birds that make the outlying 

 portion of the north-east of Scotland their halting place, and 

 also for notices and full descriptions of rare visitants that have 

 occurred in that district during the last eight or ten years. 



My acknowledgments are also due to Professor Newton of 

 Cambridge; J. H. Gurney, Jun., Esq. of London; R. G. Ward- 

 law-Ramsay, Esq., 67th Regiment; Dr Dewar of Glasgow; the 

 Rev. Alexander Stewart of Ballachulish ; and Mr J. Hardy 

 of Old Cambus, Berwickshire; to Dr Saxby, late of Unst, 

 Shetland; Mr Reid, formerly resident in Kirkwall, Orkney; 

 and Mr Joseph H. Dunn, Stromness. Through the last named 

 correspondent I have had an opportunity of consulting a copy of 

 Messrs. Baikie and Heddles' Historia Naturalis Orcadensis, with MS. 

 additions by one of the authors to 25th June, 1853. This work, 

 for convenience, has been referred to as the Fauna Orca.densis, and is
