Muriate of Potash. — Wodan Pyrites,-^ Piper Culeba. 227 



ceeding up the Sound when the Cambrian was returning ; but 

 whether they would go further up or not, is uncertain. Some 

 shins have this season been as far norih in Baffin's Bay as SO 

 degrees. The general opinion among the whalers is, that Parry 

 has discovered an inland sea ; but whether he will be enabled to 

 get through, or not, is problematical. Captain Fleming, of the 

 Lady Jane whaler, just arrived at North Shields, was told by 

 Captain MacWilliam, of the British Queen, whom he spoke on 

 the 15th of August, that he had discovered what he took to be 

 a new race of people ; but whether the same as was seen by 

 Captain Ross, he could not ascertain. 



MURIATE OF POTASH IN RO€K SALT. 



Dr. Wollaston's discovery of the existence of muriate of potash 

 in sea water, induced M. Vogel to examine whether this salt 

 might not be detected in common salt obtained from springs, or 

 dug solid out of salt mines. He subjected salt from Hallein and 

 from Berchtesgaden to experiment. Nitromuiiate of platinum 

 produced no precipitate in the simple solutions ; but when they 

 were concentrated till a large portion of the common salt was 

 extracted, they gave a yellow precipitate with this nitromuriate, 

 indicating the presence of potash. Brine from Rosenheim treated 

 in the same manner gave a similar result. — {Gilbert's Annalen.) 



WODAN PYRITES. 



Some time ago it was announced that M. Lampadius, of Frei- 

 berg, had discovered 20 per cent, of a new metal in this ore, 

 differing as much from nickel as tellurium from antimony, and 

 to which he had given the name of loodanium. 



The same mineral has since been analysed bv M. Stromeyer, 

 but without detecting in it any new metal. 100 parts contain 



Nickel 162390

ANALYSIS OF THE PIPER CUBEBA. 

 The seeds of this plant, according to a late analysis by 

 M. Vaufjuelin, contain: — 1. A volatile oil, almost concrete. — 

 2. A resin refiembling that of the balsam topaiva. — 3. Anoilter
