 veined gneiss; that it had, while in a fluid state, acted upon the gneiss, penetrated it in the form 

 of veins, and raised up its mass in such a way as to produce all the phenomena of elevation. The 

 sutors of Cromarty are good examples of what is here stated. Many other examples may, if we 

 mistake not, be derived from the works of Dr. MacCulloch. 



* The Crinoidal remains mentioned in this table were obligingly examined by Mr. Miller, who 

 found them to be identical with those occurring in the limestone of the Avon beds 1. and 9. —
