 8 atoms water . . = 9

Whether the gold and the sodium exist in this 

 salt in the metallic state, or in the state of ox- 



*M. Figuier has more recently published the result of a new analysis 

 of this salt, which approaches exceedingly near what I have given in the 

 text. Probably the small differences are owing to the different data from 

 mine, according to which his calculations Were made. He found the con- 

 stituents as follows : 



Bichloride of gold . 34-99 



Chloride of sodium . 7-13 



Water . . . 8-38 



50-50f 



Chloride of potassium likewise forms a triple salt, with the solution of 

 gold. It crystallizes in prisms, is not altered by exposure to the at- 

 mosphere, and has a striking resemblance to the salt described in the text. 

 It has been analyzed by M. Javal, who found the constituents to be 



Chloride of gold . 68-64- 



Chloride of potassium . 24- -26 



Water . . . 7-10 



100-00 

 Probably it consists of 



1 atom bichloride of gold . 34. 

 1 atom chloride of potassium 95 



4 atoms water . . . 4, .5 



48 



Javal's analysis does not agree very well with the preceding supposition. 

 His quantity of chloride of potassium indicates very nearly 2 atoms. I 

 have not myself made any experiments on this triple salt. See for Javal's
