4:82 Wells — Composition of Triple Chlorides. 



Summary. 



The conclusion has been reached from a consideration 

 of Bayer's statements and from calculations made in 

 connection with his analyses that the triple salt Cs 2 Ag- 

 AuCl 6 is a definite, invariable compound, and that Bayer 

 analyzed mixtures of this salt with CsgAiigCln and 

 CsAuCl 4 . It has been concluded also, from Bayer's own 

 analyses, that the rubidium salt is also invariable and has 

 the formula Eb 6 Ag 2 Au 3 Cl 17 corresponding to that of 

 Pollard's ammonium salt. Finally it has been concluded 

 from analogy that Suschnig's confirmation with the 

 bromides of Bayer's incorrect theory in regard to the 

 chlorides must also be wrong.
