The analysis of these platinum-compounds proved them to be the 

 salts of two bases, the formation of which in the above reaction was 

 pointed out by theory, namely, of 



Diethylene-triethyltriamine C 10 H 25 N 3 =(C 2 H 5 ) 3 



and 



Triethylene-triethyltriamine C la H a7 N 3 =L 2 -g- 4 < 3 I N 3 . 



Both these bases are oily liquids, powerfully caustic, extremely 

 soluble in water, which boil between 220 and 250. I have not 

 prepared them in quantity sufficient for an accurate determination of 

 their boiling-points. Both form neutral crystalline salts which are 

 extremely soluble in water, and also, though less so, in alcohol. 



I have established the composition of triethylated diethylene-tria- 

 mine by the analysis of the chloride and bromide, which contain re- 

 spectively,

I have also determined the composition of the platinum-salt and 

 of the gold-salt. Both are well-defined beautifully crystalline com- 

 pounds containing,

The simple salts of triethylated triethylene-triamine are far more 

 soluble than those of the triamine previously mentioned. I have 

 therefore been satisfied to establish the composition of their base by 

 the analysis of the platinum-salt and of the gold-salt. The platinum- 

 salt is extremely soluble in water, and crystallizes only when the solu- 

 tion is evaporated nearly to dryness. The analysis of these compounds
