A paper was then presented by Dr. J. S. Newberry, illustrated

 in it at six dollars per karat. It is now sold at twenty-five cents 

 per pound in quantity. 



The President remarked on the character of the alteration,

 realgar from Felsobanya, Hungary, of square prisms of humboldt- 

 ilite, in slag, and of spines of Gyracanthus tuherculatus (?) Ag., 

 from the Coal-measures at Lesmahagow, Scotland. 



Mr. G. F. Kunz then exhibited a collection of gems, some from
