“ On this trip the engines were in operation for 73 hours without being stopped for a moment, and without requiring the slightest adjustment, the consumption of fuel being only five tons in 24 hours; but her speed was not great enough, and the caloric engines were subsequently replaced by steam engines. For several years Ericsson devoted himself to the improvement and perfection of the caloric engine and its application to pumping, printing, hoisting, grinding, sawing, turning light machinery of various kinds, working telegraphic instruments and sewing machines, and propelling boats. ”

“ The lightness and compactness of this boiler led to many new applications of steam, and among others to Ericsson's construction of a steam fire engine, which was entirely successful. He constructed a similar engine of greater power for the king of Prussia. For this invention he received the prize medal of the mechanics' institute of New York. In 1833 he reduced to practice his long cherished project of a caloric engine, and submitted the result to the scientific world in London. ”

“ He has since devoted much attention to the construction of solar engines.—His brother Nils, born Jan. 31, 1802, served in the Swedish army, and from 1858 to 1863 in the navy. He was director of Swedish railways, constructed the canal between the Saiman and the gulf of Finland, the docks of Stockholm, and other public works, and was ennobled. He died in Stockholm Sept. ”
