CHLOROXALIC ACID. 



M DUMAS has obtained a compound of chlorine and oxide of 

 carbon, to which he has given the above name. This compound 

 contains the same quantity of oxide of carbon as the chlorocarbonic 

 acid, but combined with only half the quantity of chlorine. It is 

 prepared by treating crystallizable acetic acid with chlorine, ex- 

 posed to solar influence 5 the chlorine must be in excess. 



It crystallizes in rhombs, is fusible at45 c Fahr., is deliquescent and 

 volatile 3 it dees not act either upon the salts of lime or of silver. Its 

 taste is very remarkable, and is both bitter and sharp. The impres- 

 sion produced upon the tongue is so caustic, that the skin whitens 

 immediately, as if oxygenated water had been applied to it. All the 

 chloroxalates are soluble. Le Globe, 14 October. 



POTASH FROM FELSPAR. 



According to M. Fuchs, this important alkali may be extracted 

 from minerals containing it, by the following method : They are 

 to be calcined with lime, then left for some time in contact with 

 water, and the liquor filtered and evaporated. M. Fuchs says he 

 has thus obtained from nineteen to twenty parts of potash from fel- 

 spar, per cent, and from fifteen to sixteen from mica. Royal Inst. 

 Journal. Ann. de V Industrie, v. 278. 



We presume, from the quantity of potash stated to be obtained 

 from these minerals, that it is estimated in the form of hydrate.
