perature requisite for this reduction is so nign, 

 that the greatest part of the muriate of potash is 

 volatilized. The weight of palladium obtained 

 from 10 grains of the triple salt was 3*08 grains. 

 Now, it was shown by a preliminary experi- 

 ment, that the potash in this salt bears to the 

 palladium the ratio of 6 to 7 5 consequently, 

 10 grains of the salt must contain 2*64 grains of 

 potash. 



The palladium in the salt is doubtless in the 

 state of oxide. If the atomic weight of palladi- 

 um be 7> and that of oxide of palladium 8, then 

 (since 7:8:: 3-08 : 3-52,) 3-52 grains must be 

 the weight of oxide of palladium in 10 grains of 

 the triple salt. 



Both of these bases in the triple salt are com- 

 bined with muriatic acid. Now, the atomic 

 weight of muriatic acid being 4*625, it is evi- 

 dent that 8 grains of oxide of palladium will be 

 just saturated by 4*625 grains of muriatic acid ; 

 and 3 '52 grains of oxide will require for satura- 

 tion 2-035 grains of muriatic acid. 



And, since 6 potash require 4*625 of muriatic 

 acid, 2*64 grains of potash must require for sa- 

 turation 1 -526 grain of muriatic acid. 



From this it appears, that 2*035 grains of mu- 

 riatic acid are in combination with the oxide of 

 palladium, and 1*526 grain with the potash. 



These calculations enable us to state the con-
