3 grms. of this peroxide require 4 grms. of chloride of silver as equivalent to the 
oxygen it contains. Thus the experiments from 1 to 6 in this series, were made with 
a proportion of the chloride, on the whole greater than the experiments 5 to 9 on the 
first Table. Yet a great diminution is to be observed in the loss of oxygen ; in experi-
