PROFESSOR J. W. MALLET ON THE ATOMIC WEIGHT OF GOLD. 
437 
the experiments of Stas, and representing, with greatest probability, the values as at 
present known to us. They are as follows :— 
H = 1. 
Ag = 107 66. 
Cl = 35-37. 
N = 14-01. 
C = 11-97. 
Calculated Results. 
The following are the values obtained for the atomic weight of gold from the 
different series of experiments ;—
