part 4] THE PLIOCENE DEPOSITS OF COENWALL, 877 



■case. In reply to Mr. Part, the Author said that he had noticed 

 the resemblance of the andalusite from the Grlacial gravels of 

 Pembrokeshire to the Pliocene species, but there was little doubt 

 in his mind that the source of the Pembrokeshire deposits was from 

 the west, possibly from an area now covered by the Irish Sea. 

 In answer to Mr. Crook, the Author discussed the methods of 

 sampling in the field at equal intervals along the strike of the 

 deposits, and at each change of the lithological facies in vertical 

 sections. The Author agreed with Dr. Evans that probably 

 Cornwall stood at a higher level in early Tertiar}^ times than it does 

 at present ; he specially drew attention, however, to the distinction 

 necessary between the Tertiary deposits now occurring on either 

 side of Dartmoor. In reply to Mr, Newton's criticism of the use 

 of the word ' Pliocene ' in connexion with these deposits, the 

 Author said that this was essentially a palseontological aspect of 

 the subject, and one which he did not feel competent to discuss ; 

 he had alwaj-^s been content to accept as a basis the admirable 

 work of the late Mr. Clement Eeid on the Pliocene Deposits of 

 Britain.
