ON THE PLANT REMAINS IN THE SCOTTISH PEAT MOSSES. 69 



In conclusion, I wish to express my thanks to Dr Horne, F.R.S., for much valuable 

 help and advice and for the use of Geological Survey maps, both published and in 

 manuscript. My best thanks are also due to Professor Geikie, LL.D., D.C. L, F.R.S., 

 for many suggestions. 



The scientific expenses of this investigation have been defrayed by a grant from the 

 Government Grant Committee of the Royal Society, London.
