coloured after several minutes' boiling,* and on being decomposed by 

 sulphuretted hydrogen, furnished a solution which, after being evapo- 

 rated on the water-bath and filtered, showed a brown tint, and gave 

 after several days brownish-red crystals. These were purified by 

 crystallisation from boiling alcohol, in which they are very slightly 

 soluble. By the cooling of the solution a salt was obtained, which 

 crystallises in brilliant scales, possessing a brownish tint, and corre- 

 sponding exactly to the formula of a chloroplatinite of oxethyl-a- 

 collidine, C 10 H 15 (PtCl)NOCl.

This salt is derived from the chloroplatinate of oxethyl-a-collidine by 

 loss of hydrochloric acid : — 



(C 10 H 16 NOCl) 2 PtCl i =2HCl+(C 10 H 15 NOCl)oPt01 3 . 



The crude chloride of oxethyl-a-collidine, or the chloride separated 

 from the unaltered chloroplatinate by sulphuretted hydrogen, treated 

 with chloride of gold, furnishes an abundant precipitate, which con- 

 denses directly into dark yellow drops. f These drops soon transform 

 themselves into crystals, which melt under hot water, but are soluble 

 in a large quantity of boiling water. The solution, when cooled, 

 deposits first yellow drops, then magnificent thin needles of golden- 

 yellow colour. They are the chloroaurate of oxethyl-a-collidine, 

 C 10 H 16 NOCl.AuCl 3 .

Action of Ethylene Chlorhydrin upon Quinoline. 



The quinoline which was employed in this experiment was obtained 

 by distilling cinchonine with hydrate of potassium, and possessed, 

 after a great number of rectifications, the boiling-point 238 — 240° C. 

 The quinoline was heated with an equivalent quantity]: of glycol 

 chlorhydrin, to which its weight of water had been added. After 



* In one experiment an elimination of a small quantity of platinum which 

 blackened the liquid was noticed. 



t With the crude chloride a dark coloration, due to a reduction of the gold salt 

 by some impurity, is observed. 



X 16 grs. of quinoline for 10 grs. of chlorhydrin.
