 Describes the Neogene freshwater beds of Vaspatak, &c. in S.E. 

 Transylvania. The lower beds are clays with valuable lignite and 

 iron-ore ; these belong probably to the base of the Congeria-beds. 

 Above are sands, &c. with abundant Congerice, followed by conglo- 

 merates, which, perhaps, may not belong to the Pliocene series. [For

 Nickel and cobalt occur on the Crete d'Omberenza, between Turt- 

 mann and Anniviers valleys, at a height of 2990 metres at the Turtman 

 Glacier, in the green metamorphic slates. In the former valley the 

 cobalt and nickel ores occur in veins, in the latter in layer-like deposits; 

 and in those at Kaltberg bismuth occurs. The depth reached is only 

 18 metres ; but the ore-bearing localities are so far separate in hori- 

 zontal distance and in level that the deposit will probably prove to 

 be of great depth. Analyses of ores are given. E. B. T.
