V PEEFACE. 



Rev. Dr. Miles, well known to naturalists for his researches in the 

 Clyde, conducted under the auspices of the British Association, has 

 kindly drawn up a pretty full account of the more remarkable 

 creatures inhabiting the Arran shores. To those engaged in scien- 

 tific inquiries, the complete list of species which he has added, 

 brought down to the time of his leaving Glasgow for a more impor- 

 tant sphere of labour in Malta, will prove welcome and useful. The 

 account of the Flora of Arran has been drawn up by the Author's 

 eldest son. To Professor Balfour, of Edinburgh, his best thanks are 

 due for the permission kindly granted to make use of his catalogue 

 of Arran plants. The list of plants and localities now given has 

 been thus considerably extended. 



The Author has also to acknowledge his obligations to H. T. 

 Stainton, Esq. of Mountsfield, near Lewisham, whose high reputa- 

 tion as an entomologist is well known, for the notes which he has 

 most kindly supplied on the rarer insects of Arran. 



In examining the lower members of the coal series in the Campsie 

 district, the Author was directed and assisted by Mr. John Young, 

 then of Lennoxtown, now of the Hunterian Museum, Glasgow . 

 Two of the illustrative cuts in the early part of the work, and many 

 facts there stated, were supplied by him. Many important facts 

 were also kindly supplied by James King, Esq. of Levernholm, 

 regarding the lower coal series. Through the kindness of the Rev. 

 David Landsborough of Kilmarnock, son of the late distinguished 

 naturalist, the Author was put in communication with John M'Kin- 

 lay, Esq. of Bonnington, near Edinburgh ; and from this well known 

 archaeologist much valuable information has been received. The 

 accompanying map has been reduced by Messrs. W. & A. K. John- 

 ston from the Admiralty Survey of 1846. According to Mr. Paul 

 Cameron, the magnetic variation in the Frith of Clyde at present 

 amounts to 26 35' W., with a decrease of 4' to 5' per year, westerly.
