J According to these observations the gaseous mixture contains 26.0 of carbonic acid, and 74.0 of combustible gas, of which (experiment VII) 29.23 vols, require 101.37 vols, of oxygen for complete combustion, producing 58.4 vols, of carbonic acid, which closely corresponds with the ratio, 1 : 3^ : 2 ; hence it appears that the gas evolved with carbonic acid, at the positive pole, is actually methyl, containing not even a trace of marsh-gas, which requires the double volume of oxygen for its complete combus- tion, and produces only an equal volume of carbonic acid. acid (dry).
