CORRIGENDUM. 



At page 69, in the abstract of a paper by the Rev. D. Williams, it is stated that 

 ** the soft and rotten condition of the Syenite has no doul^t obtained for it the name 

 of pottle stone, by which it is locally known, since it was formerly wrought for 

 skins and other culinary vessels.' Tliis does not give a proper ^iew of the author's 

 meaning. He intended only to infer from the name of 'pottle stone' locally 

 applied to the rock in question, which is a free-working talcose or steatitic Syenite, 

 that it might have been formerly worked for culinary purposes.
