The analysis resulted as follows : — 



0.2060 gr. substance gave 0.6 10 1 gr. carbon dioxide and 

 •0.1452 gr. water, equal to 0.16638 gr. C. and 0.01613 gr. H.

Derivatives of Diphenisamylamine. 



The Platinum Double Salt — (Coo Hg,, NH . HCl), Pt CI,. 



The salt was best prepared by conducting dry hydrochloric 

 acid gas into an ether solution of the base. The ether was 

 evaporated and an oily compound obtained which dissolved 

 readily in absolute alcohol. 



The addition of an alcoholic solution of platinum-chloride 

 to this solution, gave after some days' standing a compact, 

 dark-golden, slightly crystalline body, which was difficultly 

 soluble in hot alcohol. After thorough washing with water 

 it was dried over sulphuric acid, and finally at ioo°-i 10°. 

 The analyses were as follows : — 



I. 0.2416 gr. substance gave 0.04450 gr. platinum. 

 II. 0.3396 " " " 0.06384 "
