These numbers agree pretty closely with those required by 

 the theory, C 10 H 14 N CI, Pt CI 2 , while the excess of platinum 

 obtained in analyses III. and IV., made with a salt recrystallized 

 by the aid of heat, is probably to be explained by the result of 

 an experiment in which we have proved that the cespitine pla- 

 tinum salt yields a platinized derivative when boiled with water. 

 Before proceeding to describe this new substance, we give the 

 results furnished by an analysis of the pure base cespitine.

 The platinum salt of cespitine, which is but slightly soluble 

 in cold water, dissolves readily in boiling water ; and the solu- 

 tion, if kept in steady ebullition for half an hour, deposits bril- 

 liant pale yellow scales, the supernatant liquid becoming colour- 

 less. 



During this transformation hydrochloric acid is evolved in 

 considerable quantity, and may be readily detected at the mouth 

 of the vessel. The reaction proceeds as follows : — 



C ,0 H 14 NCl,PtCl 2 =C 10 H 13 PtNCl 2 + HCl, 

 and is perfectly analogous to the change produced in the pla- 

 tinum salts of pyridine and picoline by ebullition with water, 

 although it is effected with much greater ease, and its produc- 

 tion is not preceded by that of a double compound containing 

 one equivalent of the original united with one of the changed 

 salt. 



The composition of the new crystals was ascertained by the 

 analysis given below: — 



I. 0*3715 grm. gave 0*316 grm. carbonic acid and 0*2085 

 grm. water. 



II. 0*42 grm. gave 0*1605 grm. platinum. 

 III. 0*2595 grm. gave 0*099 grm platinum. 

 IV. 0*2018 grm. gave 0*077 grm. platinum.
