compounds in contradistinction to the former class, which are tetr- 

 ethylated. 



The platinum-salt is readily obtained by dissolving the triethylated 

 base in hydrochloric acid, and adding dichloride of platinum. The 

 precipitate may be crystallized from boiling water without decompo- 

 sition. The salt forms beautiful rhombic prisms of the composition 



C 8 H 18 N0 a Pt C1 8 = [(C a H 5 ) 3 ( C A ')N]C1, Pt C1 2 . 



The gold-salt crystallizes in needles difficultly soluble in cold, 

 easily soluble in boiling water, in which they fuse. Their composi- 

 tion is analogous to that of the platinum-salt, 



C 8 H 18 NO, Au CI,= [(C, H s ) 3 ( C g> )N] Cl, Au C1 3 . 



The nitrate is formed by dissolving the triethylated compound in 

 nitric acid, evaporating the solution to dryness, dissolving the residue 

 in alcohol, and adding ether, when the salt crystallizes out in splendid 

 needles very soluble in water. The combustion of the compound led 

 to the formula 



c. H 18 N a o s = [(c, H 5 ) 3 ( c .)N]NO,. 



The only additional salt of this series which I have examined is 

 the iodide. It is formed by dissolving the triethylated compound 

 in hydriodic acid, evaporating, washing the crystalline residue with 

 strong alcohol, and recrystallizing from boiling alcohol. The crystals 

 are generally well-formed ; they are extremely soluble in water. 

 The composition of this salt presents some interest. Analysis proved 

 it to contain 



C 18 H 3J N,OJ= [(C 2 H 5 ) 3 ( C -')N]I. C 8 H I7 N0 2 . 



From the analysis of these salts it is evident that the action of oxide 

 of silver upon the compound of triethylamine with chloracetic ether 

 is twofold : in the first place, the chloride is converted into the cor- 

 responding base ; in the second place, this base loses an equivalent of 

 ethyl, which separates in the form of alcohol : 



=AgCl+ * l 0+> O.
