Mr Kenwood on the Phenomena of 



or naturalists to follow my steps, and assist me to throw, at 

 last, some light upon the topography and natural history of 

 that beautiful empire, European and Asiatic Turkey, to the 

 investigation of which I have devoted the remaining best days 

 of my life. 



A Lecture on the Phenomena of Metalliferous Veins ; delivered 

 at the Penzance Institution, on Tuesday the lOth of Novem- 

 ber 1836. By W. J. KENWOOD, F. G. S. London and Paris, 

 Assay Master of Tin in H. M. Duchy of Cornwall. 



THE Chairman, Dr Boase, Secretary of the Royal Geologi- 

 cal Society of Cornwall, opened the proceedings by stating, that, 

 having himself given a lecture on Geology generally, it was in- 

 tended to take the various departments in detail. In course, it 

 would have been his object to have described the primary, or 

 non-fossilliferous rocks, leaving the subject which would form 

 the present evening^ lecture to follow it. But the question of the 

 origin of veins, had been recently taken up by Mr Fox, and 

 having deservedly attracted so much attention, it had been 

 thought advisable to follow it up whilst the impression remained. 

 Mr Kenwood had, for several years, been engaged on the sub- 

 ject, and had inspected most of the mines in this and the adjoin- 

 ing county ; the results of his labours were in a state of forward- 

 ness, and would shortly be before the public, in the fifth vo- 

 lume of the Royal Cornwall Geological Society's Transactions. 



The Lecturer said that it had been originally his intention to 

 have refrained from publishing any of his observations, or the 

 views to which he had been led by them, until he could do so 

 in a connected form ; and in this determination he had for some 

 years persevered. Finding, however, that vifews from which he 

 almost entirely dissented, were before the public, on the high 

 authority of a gentleman for whom he had the greatest respect, 

 and to whom he felt himself much obliged, he had thought it 

 might not be improper to give an outline of them ; and he felt 

 the more satisfaction in doing so, as he believed they were in 

 unison with the opinions of almost all the practical men of this 

 county.
