Destructive Distillation of Animal Substances^ 467 



tables, sometimes very distinct, at other times confused and ir- 

 regular. It dissolves very readily in cold water, and still more 

 abundantly in boiling, and appears also to be very easily soluble 

 in excess of hydrochloric acid. Numerous analyses of this salt 

 were made, of which the following are the results : — 



No. 1. This was the analysis of the salt prepared from the 

 oil distilling between 315° and 325*^ in the seventh rectification. 



6*377 grs. of platinochloride gave 6*187 of carbonic acid, and 

 1*915 of water. 



6*810 grs. platinochloride gave 2*146 grs. platinum. 

 64*76 ... ... 2*051 



No. 2. Portion of the oil distilling between 295° and 300° in 

 the fourteenth rectification ; the platinum salt of picoline was 

 separated by crystallization, and the salt analysed precipitated 

 by alcohol and aether. 



7*906 grs. gave 2*491 grs. platinum. 



7*835 grs. of the salt recrystallized gave 2*470 grs. platinum. 



No. 3. Another preparation from the same portion of oil. 



7*330 grs. of platinochloride gave 7*070 carbonic acid and 

 2*090 water. 



6*830 grs. gave 2*155 grs. platinum. 



No. 4. Portion of the oil boiling between 300° and 305° in the 

 thirteenth rectification. 



7*40 1 grs. gave 2*328 grs. platinum. 



No. 5. Portion boiling between 325° and 335° in the seventh 

 rectification. 



7*194 grs. gave 2*256 grs. platinum.
