64 UPON A NEW COMPOUND OF THE DEUTO-CHLORIDE OF PLATINUM, 



Summary. 



23. Making a summary of the foregoing several experiments, we find that 

 the per centage of the platinum, 



By experiment 11, is 41.08 



« 12, " 40.19 



" 13, " 41.51 



" 18, " 41.16 



" 21, " 42.36 



5)206.30 



Giving, as a mean, 41.26 



24. The per centage of the chlorine, 



By experiment 17, is 43.32 



20, " 44.46

2)87.78 

 Giving, as a mean, 43.89 



25. The per centage of the nitric oxide gas, 



By experiment 15, is 4.86 



16, " 5.09 



2)9.95 



Giving, as a mean, 4.98 



26. The platinum and the chlorine have already been shown (19 and 22) to 

 exist in the salt in the proportion of one atom to three atoms. But, of the three 

 atoms of chlorine, two go to form one atom of the deuto-chloride of plati- 

 num, while the remaining one atom, united with one atom of hydrogen, exists 

 in the form of hydro-chloric acid.
