HYDES INCUBATOR. This was designed and constructed for the pleasure and use of HYDES INCUBATOR. 81 the inventor, but as several of them have been made and foundtheir way into other hands, it is well to give a short descriptionof it. The heating arrangement is similar to Vallees; the machinestands on four legs like a table; on the opposite end from the lampis placed the regulating apparatus. This consists of a short andlong arm revolving on the axis of a clock movement, and catchingalternately on the notched arc of one end of a lever, the other endof which is moved by a thermostatic bar in the egg chamber of themachine. Attached to this axis is also a crank, from which a very. FlG. 66.—THE CENTENNIAL INCUBATOR. light wooden rod connects with the lamp, raising or loweringthe llame as needed. Under the egg drawer are placed spongessaturated with water, to give the necessary moisture to the air. THE CENTENNIAL INCUBATOR. This machine, illustrated at Fig. 66, is the outgrowth of a greatmany experimental machines, two of which are illustrated atfigures 56 and 61. The principles embodied in the present Incubator were firstcombined and shown at the International Exhibition at Philadel-phia in 1876, from which it received its name. At that time thecase of the Incubator was of wood, and the boiler, tank and lamp 82 THE CENTENNIAL INCUBATOR. only of metal. 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-
