Professor Geikie has been so good as to give me (in a 

 letter dated Nov. 1885) his impressions of my father's article 

 in the 'Admiralty Manual.' He mentions the following 

 points as characteristic of the work : 



* A sentence occurs in this paper 

 of interest, as showing that the 

 author was alive to the importance 

 of all means of distribution : " The 

 fact that particles of this size hav- 

 ing been brought at least 330 

 miles from the land is interesting 

 as bearing on the distribution of 

 Cryptogamic plants." 



t An extract from a letter to 

 Lyell, 1847, is of interest in connec- 

 tion with this essay : " Would you 

 be so good (if you know it) as to 

 put Maclaren's address on the en- 

 closed letter and post it. It is 

 chiefly to enquire in what paper he 

 has described the Boulders on 

 Arthur's Seat. Mr. D. Milne in the 

 last Edinburgh ' New Phil. Journal ' 



[1847], has a long paper on it. He 

 says : ' Some glacialists have ven- 

 tured to explain the transportation 

 of boulders even in the situation of 

 those now referred to, by imagining 

 that they were transported on ice 

 floes,' &c. He treats this view, 

 and the scratching of rocks by ice- 

 bergs, as almost absurd ... he has 

 finally stirred me up so, that (with- 

 out you would answer him) I think 

 I will send a paper in opposition to 

 the same Journal. I can thus in- 

 troduce some old remarks of mine, 

 and some new, and will insist on 

 your capital observations in N. 

 America. It is a bore to stop one's 

 work, but he has made me quite 

 wroth "
