The mixed gases were thenmade to stream through the usualform of condensing apparatus, andwere afterwards compelled to passsuccessively through wet and drylime purifiers before they reachedtlie gas-holder. In order to securea uniform mixture of the gas pro-duced in each experiment, it wasallowed to remain at rest in the gas-holder for at least twelve hours be-fore a specimen was withdrawn foranalysis. In the following tables both thepractical and analytical results aregiven. Practical Results. Averageevolu-tion of Gas perhour. Materials Consumed. Products Obtained. Eesin. Coal. Char-coal. Lime.
