Thefirst portions that pass overare mixed with air, and shouldbe rejected, as the mixture isdangerously explosive. One of the most strik-ing properties of free °hydrogen is its levity. It is the lightest body in nature,being fourteen and a half times lighter than common is hence used in filling property is its combustibili-ty; it inflames on contact with alighted taper, and burns with a flamewhich is intensely hot, though scarce-ly luminous if the gas be pure. Final-ly, it is itself incapable of support-ing the combustion of a taper. Exp. 13.—All these characters may be shown by the following singleexperiment. A bottle full of hydrogen is lifted from the water overWhich it has been collected, and a taper attached to a bent wire, fig. 7, is.
