CONVERSATIONS on MINERALOGY; with Plates, en- 

 graved by Mr. and Miss Lowry, from Original Drawings, comprising up- 

 wards of 400 Figures of Minerals, including 12 beautifully coloured Speci- 

 mens. 2nd Edition. In 2 Vols. 12mo. Price 14s. boards. 



" The plan of these Conversations is happily conceived, and it is executed 

 with ability and taste. The Author has studiously avoided all unnecessary 

 parade of technical diction, has rendered the doctrine of Crystallography 

 more familiar than heretofore to the Tyro in Mineralogy, and has included 

 some of the most recently discovered substances. We may therefore un- 

 hesitatingly characterize this Work as one of the most desirable Text Books 

 that have issued from the British Press." — Monthly Review.

 scientific description, may be found useful." — Preface.
