194 Mr. Levi/ on Two new Minerals. [March, 



requires further elucidation, and I am sure Dr. Thomson is too 

 candid to object to its being fully discussed, however clear the 

 evidences may appear to his own mind.

Descriptions of Two new Minerals. By Mr. A. Levy, MA. FGS^ 

 (To the Editors of the Annals of Philosophy.) 



GENTLEMEN, 



Among many very interesting specimens, and several unde- 

 scribed substances, which were in the collection of Marquis de 

 Dree, and which Mr. Heuland, who lately bought it, has added 

 to his own private collection, are the two of which 1 now send 

 the descriptions for insertion in the Annals of Philosophy, and 

 which belong, I believe, to two new species. For one of them 

 I propose the name of Beudantite, in honour of Mr. Beudant, 

 and for the other, at the suggestion of Mr. Heuland, the name of 

 Kdnigine, in compliment to Mr. Konig, of the British Museum. 



K'dnigine. 



The characters which distinguish this substance from any 

 hitherto described, were ascertained before the arrival of Mar- 

 quis de Dree's collection into this country upon a specimen now 

 in the possession of the Dowager Countess of Aylesford. The 

 specimen which subsequently was found to belong to the same 

 species had the following ticket {cuivre muriate et phosphate). 

 In both cases the mineral occurs in small crystals, emerald-green 

 and blackish-green, translucent, and of either of the forms 

 represented by figs. 1, 2, 3. These crystals cleave only and 

 very easily in a direction parallel to the plane P of the drawing ; 

 the face obtained by cleavage is very brilliant, and at right angles 

 to the lateral planes m. These lateral planes are generally dull
