blow-pipe, has been discovered by Dr Wohler. It occurs at 

 Grigisholm, near Stockholm, and at Skinnskatteberg, near 

 Riddarhyttan, so that it is no longer confined to the locality 

 of Kararfvet, near Fahlun. 



Carbonate of cerium has been discovered at Bastnaes, near 

 Riddarhyttan, accompanying the cerite, on which it forms 

 white crystalline coatings. According to an analysis by Mr 

 Hisinger, it is composed of 



Oxide of cerium, - - 75.7 



Carbonic acid, - - 10.8 



Water, - 13.5 



which corresponds to the formula Ce C-f2 Aq. From a 

 want of sufficient material, it has been impossible to repeat the 

 analysis, which is called for in particular by the uncertain 

 proportion of water. Along with it is found also fluate of ce- 

 rium, of a nearly orange-yellow, or wax-yellow colour, and 

 semi-transparent. It does not change its appearance, when 

 exposed to a slight red heat, by which it loses 19 per cent, of 

 its weight. It is exceedingly rare.
