CALX carbonata. 

 Fasciculated Carbonate of Lime. 



Div. l. Crystallized. 



These Crystals of Carbonate of Lime, I believe, are 

 rather scarce. The representation of a regular Crystal so 

 neatly formed by a bundle of spiculae is truly curious ', and 

 it is generally found that they have a light ochraceous or 

 brown tint with an opaque glaucous appearance, prettily 

 contrasted with the brilliancy of the Quartz on which they 

 lie. This is, we understand, one of the rarest of the 

 numerous productions of Derbyshire, and is found at a 

 considerable depth in the ground.
