hut, now existing, of tlie beehive form, and built with stones 

 overlapping from circumference to centre. — Mr. Henwood men- 

 tioned that Mr. Blight and Mr. Edmonds had described an- 

 tiquities of this kind near Penzance, and that some had been 

 discovered more recently by Mr. Cornish of that town. 



Ecclesiological descriptions of the churches at Lanteglos and 

 Tintagel were given, respectively, by Rev. J. J. Wilkinson and 

 Mr. MiCHELL Whitley ; and Captain Williams, of St. Austell, 

 described the workings of the Delabole Quarries, in relation to 

 their geological strata and the catastrophe of last year ; after 

 which discussion took place — mainly between Eev. J. J. Wilk- 

 inson and Mr. Whitley — concerning the origin and antiquity 

 of Tintagel Castle ; the contest being chiefly on Mr. Wilkinson's 

 theory that what is called " The Island " was always really an 

 island, and that the present isthmus between it and the mainland 

 is not the last vestige of a more substantial communication form- 

 erly existent, but the result of falling dSbris from each side.
