The motive power employed in the pre-sent instance was obtained from the combustion of charcoal,nitre, and gypsum, as used in the original fire annihilator;the products of combustion mixing with water in the boiler,and forming gas charged steam, which was delivered at ahigh pressure from the extremities of the eight arms.
