These deposits occur in lenticular masses in crystalline limestones, 



intercalated in a series of talcose schists of Laurentian age. The author 



has discovered three horizons of the ore. The deposits at Licone- are 



the most important. The ore is associated with asbestos, green and 



black acicular amphibole, &c., and occasionally with brucite in thin 



veins or strings ; noble serpentine is also met with. G. A. L.

Gives the name Rauite to a zeolitic mineral produced by the altera- 

 tion of eloeolite, on the island of Lamo, near Brevig, Norway. Analysis 

 leads to the formula, 2{Aip3-h(|GaO|Na,0)SiOJ +5H,0. The name 

 is derived from Ran, an old Norse goddess of the sea. F. W. R.

Contains analyses of triclinic felspars from dolerite of the Frauen- 



berg, near Heubach, and from basalt of the Steinbiihl, near Weilburg. 



Both appear to be andesine ; and the author argues in favour of the 



existence of this felspar as a distinct species. F. W. R.
