In addition to the fossil fish, however, it would appear from the contents 

 of a letter from Mr. Christie, that the blue shale of Gamrie has been also 

 found to contain vegetable impressions and other fossil remains, of an obscure 

 character ; but these are not sufficient to enable us to determine the exact 

 place of this deposit in our secondary series * : it gains, however, additional 

 interest, from the fact that chalk flints, with their characteristic organic re- 

 mains, had been discovered in considerable abundance on the granite of the 

 neighbouring shire of Aberdeen near Peterhead ; an important observation, 

 first made by Dr. Knight, and afterwards verified by Dr. Buckland and 

 Mr. Lyell. 



* It is to be remarked that some of these calcareous nodules upon being broken transversely 

 exhibit portions of galena.
