The experiments with this peroxide give about the same range of action as with the 
last. On the wliole, however, the loss here, as at 100° with the same substance, is 
rather less, but the ditference is not so apparent. 
Experiments with the Oxide of Silver at 100° C. 
The following are experiments with the oxide of silver at 100° C. The oxide was 
prepared either by precipitation with baryta water or with a pure potash. It contained 
no chloride but some carbonate, and was dried at 100°. The peroxide employed 
was the peroxide P, containing 8*34 per cent, of oxygen ; 3‘63 grins, of the oxide of 
silver are equivalent to 3 grms. of the peroxide.
