278 Description of FERGUSONITE. 



regular forms of Cerite are unknown, or, at least, as long as 

 they have not been compared with those of Allanite. Professor 

 MITSCHERLICH, however, informed me, that he had a crystal of 

 Cerite in his possession, which the crystal of Allanite, described 

 above, immediately recalled to his memory, when he was looking 

 over that department of Mr ALLAN'S collection which contains 

 the minerals belonging to the order Ore.
