Fasciculated Carbonate of Lime

These Crystals of Carbonate of Lime, I believe, are rather scarce. The representation of a regular Crystal so neatly formed by a bundle of spiculæ is truly curious; and it is generally found that they have a light ochraceous or brown lint 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.
