The new platinum -salt crystallizes in splendid, well-formed crystals 

 of rhombic habitus. They were found to contain 



C 10 H 2a N0 2 PtCl 3 =(C 2 H 5 ) 3 Nci, PtCl 



The chloride corresponding to the platinum-salt is readily obtained 

 by the action upon it of sulphuretted hydrogen. By evaporation in 

 vacua over sulphuric acid, it remains in the form of long needles, ex- 

 tremely soluble both in water and alcohol. From the latter solvent 

 it may be recrystallized. The crystals, however, owing to their de- 

 liquescent character, are but little adapted for analysis. I have 

 therefore been satisfied to corroborate the formula of the platinum- 

 salt by the examination of the corresponding gold-compound. 



The gold-salt crystallizes in needles, which, since they fuse at 100, 

 have to be dried in vacuo. 



Formula: 



C 10 H 22 N0 2 Au C1 4 = [(C 2 H 5 )/g* *N]CI, Au C1 3 . 



I have not been able to obtain the base corresponding to this 

 series of salts. The chloride, when treated with oxide of silver, .yields 

 chloride of silver and a solution which, on evaporation, solidifies into 

 a radio-crystalline compound. Although perfectly neutral to test- 

 paper, this substance forms, with hydrochloric and hydriodic acids, 

 \vcll-defined salts which belong, however, to another series, The 

 \iquid obtained by the action of oxide of silver, in addition to the 

 crystalline compound, contains alcohol which may be separated by 

 fractional distillation. The crystalline substance formed under the 

 above circumstances is rather deliquescent, and was therefore not 

 submitted to analysis. To obtain some insight into its nature, the 

 platinum- and gold-salts, as well as the beautifully crystallized 

 nitrate and iodide, were examined. Their analysis has proved that 

 these salts differ from the saline compound formed by the action of 

 chloracetic ether upon triethylamine, by the substitution of hydrogen 

 for an equivalent quantity of ethyl, a difference of composition which 

 might have been inferred from the elimination of alcohol in the pro- 

 cess of transformation. 



The new set of salts containing only three equivalents of ethyl, I 

 may, for the sake of convenience, designate them as the triethylated
