Mr. Walchner, who teaches with great success in an establishment devot- 

 ed to the arts and sciences, has conceived the project of writing a ma- 

 nual, which should present mineralogy principally in its technieal rela- 

 tions, and which may serve as a basis chiefly of his own lectures. The 

 manual will consist of two volumes, the first of which has alone appear- 

 ed. The author has arranged minerals according to their electro-posi- 

 tive elements, and, with some slight changes, has followed the system 

 which Berzelius published in his first system of mineralogy in 1819. 



Commentatio Ae Ursi longirostris Sceleto. In 4to. 20 Pp. Two 

 Plates. By Hermanni de Pommeresche. Berlin, 1829. 



The animal represented in the memoir, first figured by Cotton, (Anim. 

 Drawn, &c. 1788,) who calls it Peter bear, has been described by a num- 

 ber of naturalists, and under diiferent names, till Mr. Tiedemann gave 

 it that of Ursus longirostris, which the author is inclined to preserve. 

 The memoir only contains the figure and description of the skeleton of 

 the animal.
