Having thus, as I believe, given a somewhat full list of previous 

 writings on the subject, my next duty, and a most pleasant one, is 

 to express thanks to all those who have assisted directly or 

 indirectly in the preparation of my paper. 



To Mr John Crawford of Tongue, the Duke of Sutherland's 

 factor for the northern districts, and to Mr Thomas Mackenzie of 

 Dornoch, I have all along been greatly indebted, for the kind way 

 in which they have ever rendered me ready assistance, not to speak 

 of the pleasure I have derived from our correspondence. Special 

 thanks are also due to Mr E. Maclver, the Duke of Suther- 

 land's factor for the districts of Assynt and Edderachyllis. I shall 

 never cease gratefully to remember his unvarying kindness, 

 shown in many ways, and the trouble he so often took in all 

 matters bearing upon the objects of my excursions. 



To Mr John Sutherland, whose comfortable inn was my 

 chief head-quarters, I am much indebted. His thorough know- 

 ledge of the haunts and habits of all the wild creatures, amongst 

 which he passed so many years of his life, as the Duke of Suther- 

 land's head gamekeeper, was of infinite service to me. 



To many others, too numerous to name — but whom, though 

 not now naming, I well remember — I desire to express sincere 

 thanks, not only for help given in my pursuits, but also 

 for their light-hearted, cheerful companionship in many a long 

 ramble by the lochs and streams, and wild hills and valleys of their 

 glorious county. 



Professor Newton, Sir William Jardine,* Mr Eobert Gray, and 

 others with whom I have corresponded, I would thank for their 



* Since the above was "written, Sir William Jardine died at his residence, 

 Jardine Hall, Dumfriesshire, at the age of 74, regretted by a wide circle of 

 scientific and personal friends, on the 21st November, 1874.
