 joint observations, coupled with records from every available source. I was 

 supplied by Professor 0. J. Patten with voluminous field-notes of five visits to 

 Clare Island, and with many skins and photographs taken there by him ; by 

 Mr. N. H. Foster with tabulated lists of his observations, both on the island 

 and mainland ; and by Mr. E. M. Barrington with observations and specimens, 

 and schedules of light-keepers. I have, moreover, to thank the last-named 

 for constant advice and assistance in the preparation and revision of the 

 manuscript. Some of Mr. Welch's beautiful photographs, taken for the 

 Survey Committee, enhance the value of the present report ; and I have 

 to thank the several gentlemen named under the head of " Field-work " 

 for filling up schedules at my request, and Mr. H. Blake Knox for his 

 photograph of the Snowy Owl.
