The folloAving year the machine was remodelled,and constructed entirely of galvanized iron, save the heating ar-rangements, which are of copper. The growth of this machine may really said to have begun in1865, at which time the writer began his first experiments in Arti-ficial Incubation, but it was not until 1878 that The Centennial ap-. peared in its present form and took its hard-earned position as theStandard Incubator of America, if not of the world. As nearly one hundred of them are in use on the ostrich farmsof South Africa, and fully fifty more distributed in England, Ger-many, Australia, Cuba, Mexico and Brazil, the title is not inappro- PIThe Incubator consists of a copper boiler and tank, the boiler THE CENTENNIAL INCUBATOR. 83 encased with an outer jacket of galvanized iron, and the space be-tween packed with mineral wool. The tank is enclosed by a caseof galvanized iron, outside of which is still another case of samemetal, with intervening space also packed with non-conductingmaterial; this space is from two to three inches thick. Inside thetank is a system of tubes which bring the water from the boilerand so distribute it that the outer edges of the tank are the hot-test ; the water, as it cools, is taken up by the return flues andconveyed back to the boiler, to b
