OUTLIER IN THE ENGLISH CHANNEL. 315 



the evidence also of the occurrence of ochreous ash 10 miles S.W. of 

 Falmouth itself. 



I do not think it advisable to attempt more precise localization ; 

 but there can be little doubt that this submarine Triassic patch is 

 considerably larger than any of the land outliers of Devon. Hitherto 

 Portledge and Peppercombe in Barnstaple Bay, and Cawsand in 

 Plymouth Sound, have been the most westerly points known of the 

 English Trias. We are now enabled to carry it some fifty miles 

 further to the south-west. 



Discussion, 



The President pointed out the great interest of the facts observed 

 by the Author, and thought that his conclusions were highly prob- 

 able. 



Eev. A. Irving owned to a feeling of uncertainty as to whether 

 the Author's conclusions could be regarded as well founded. Ho 

 thought that the probability was that off the Lizard there are a 

 number of erratic boulders, many of which may be derived from the 

 Trias, but at the same time he indicated the difficulty of identifying 

 these sandstone rocks when there was no palasontological evidence 

 to go upon. 



Mr. HuDLESTON thought the evidence of the rock being in situ was 

 satisfactory. 



Pev. A. Irving remarked that large boulders would split along 

 the bedding-planes.
