The Comparison of Caesic and Argentic Chloride. 

 Ag = 107.930 ; CI = 35.455. 



ride were 3.970 and 3.975. The average, 3.972, agrees sufficiently 

 well with the value 3.992, found by Setterberg.* Therefore, for every 

 gram of caesic chloride, as weighed in air, 0.00016 gram has been added 

 to correct the observed weight.
