M. Bonnemain also usedsponges saturated with water in the bottom of the egg chamber,to supply moisture to the air. He also constructed a regulatingbar, formed of two different metals, (probably iron and brass),which acted upon a damper in the furnace door, thus increasingor decreasing the draft of the eggs were lain on slides as shown in the illustration. The. Fig. 50.—carbonniers was not a success, owing to the impossibility of keep-ing the temperature even on the different slides. THE ECCALEOBION. Next after Bonnemains, as near as we can tell, was an inven-tion which was shown in London, and called an Eccaleobion: thiswas heated by steam pipes, with jugs of water in the egg cham-bers to keep the air moist. In 1842, a small machine was exhibited in operation at Bristol,Eng., by a Mr. Appleyard; we have no description of it. Aboutthe same time one was exhibited by Mr. E. Bayer, in New Yorkand Brooklyn, called the POTOLOKIAN. And between this and 1845, a Mr. L. G. Hoffman of Albany, in-vented and had in operation, the AMERICAN EGG HATCHING MACHINE, of which Fig. 49 is an illustration.
