Similar to Minasis first machine, was one constructed by Adrien& Trioche, at Van Girard, France, in 1848. This also had the rub-ber cloth bottom to the water tank, supported on rods of sheet iron cylinder, heated by a charcoal fire, supplied the tankwith hot water. The top of the tank was covered with sand, so as ADRIEN & TRIOCHEs INCUBATOR. 67 to retain the heat. This Incubator was ten feet long by three anda half wide. The drawers were in two ranges, placed back toback; the bottoms of the drawers were of perforated tin or finewire cloth, covered with bran to keep the eggs level.
