we find that he had been as hard at work at his favourite subject 

 as ever. One of his memoirs treats of the Geology of the Isle of 

 Man, which he was wont to regard as a kind of geographical link 

 between the Geology of Ireland and that of Cumberland and 

 Westmorland. There is another on the Dingle Promontory in 

 Ireland, one on the Graptolites of the Llandovery Rocks of 

 Haverfordwest. But it was about this time — that is to say, from 

 1864 onward — that he had associated with his name in the 

 preparation of several of his memoirs, that of his friend Mr. H. A. 

 Nicholson of Penrith, now the well-known author of some of our 

 best text-books on Zoological and Palaeontological subjects, and 

 Professor of Natural History at the University of Aberdeen. 

 Nicholson had worked over a large area of Cumberland and 

 Westmorland along with Harkness some time before, and by the 

 year 1870 they had published four several memoirs under their 

 joint authorship, each paper having important bearings upon the 

 the geology of the older rocks of this part. 



It was in the autumn of 1867 that I had the first opportunity of 

 making the personal acquaintance of the subject of the present 

 sketch. This was at Penrith, where Professor Ramsay, Mr. 

 Hughes (whose extensive acquaintance with the Geology of West- 

 morland enabled him to largely make use of our local illustrations 

 when he afterwards succeeded Professor Sedgwick at Cambridge), 

 and others, had met to discuss certain questions connected with 

 the Geology of this part, where we had, only a few months before, 

 just commenced the Geological Survey. Harkness, as a writer, 

 was well-known to me long before, and I naturally felt a consider- 

 able degree of interest in making his closer aquaintance. Two or 

 three hours may seem absurdly inadequate to enable one to form 

 any judgment regarding the disposition of a man that one has 

 never set eyes upon before. But it happened that early in the 

 course of our meeting, some questions arose regarding certain 

 points in the geology of this neighbourhood wherein the conclusions 

 that some of the party had arrived at differed considerably from 

 what Harkness had previously expressed in some of his papers.
