following statements 
1. If the bottom of a vessel (filled with atmospheric air) be coveredwithanaipieiB 
solution of any of the salts mentioned, and a piece of phosphorus haring idaa 
surface placed in it, w that half iia bulk risranborellie level of the fluid, the fcnstfis 
of ozone win immediately begirt, provided the temperature be 
these circumstances the solution aKsiimes gradually a beautiful deepreddnt. Ihn
