residual matter in hot water, and evaporating 

 the solution in order to obtain the antimonite 

 which separated in the state of a white powder. 

 According to the analysis of Berzelius, the con- 

 stituents of the salt are 



Deutoxide of antimony 76-6 or 19-641 

 Potash . . . 23-4 - 6 



100-0 



It is obvious that the salt contained an excess 

 of deutoxide ; had it been a binantimonite, it 

 would have been composed of 



2 atoms deutoxide of antimony 14 or 70 

 1 atom potash . . . 6-30 



20 100 



chlorides 4. There are two chlorides of antimony, though 

 only one of them has hitherto been described ; 

 both of them may be easily obtained by dissolv- 

 ing sulphuret of antimony in muriatic acid, 

 and distilling the solution in a retort. There 

 distils off' a liquid having a straw yellow colour, 

 containing both muriatic acid and antimony. 

 The liquid in the retort, which was at first of 

 rather a deep yellow, becomes gradually lighter, 

 and at last quite colourless and transparent. 

 When the concentration has been carried a cer- 

 tain length, the fire must be withdrawn, and the 

 apparatus left untouched for twenty-four hours*
