The front is furnished with double glassdoors through which the eggs and thermometer are visible with-out opening the machine. By the scientific manner in which;he heating apparatus is constructed, every particle of heat isatilized and a great saving of oil is effected.

The formation of -the heating apparatus is such that neithersmoke nor gas can enter the egg chamber, in which the air isconstantly changing, therefore it must always be pure and whole-some. Underneath the eggs a current of cool—not cold—air iskept circulating, which, as it becomes impregnated by carbonicacid gas from the eggs, passes out through the bottom ventilators. The new Patent Eegulator is the Perfection of Simplicity, isstrong, reliable and will last a lifetime; it is connected directlywith the lamp and turns the flame up or down wit
