Made of well sea- soned quarter-sawed oak, of five-ply construction, and finished in attractive hand-rubbed light oak; insulation consists of tar paper, animal hair and transite; regularly heated by electric carbon lamps, which heat and cool quickly and are easily exchanged, provided with steel chimneys for protection and for promoting even distribution of heat; if desired, can be furnished with pilot lamps, instead of carbon, at same cost; heat is automatically controlled for tempera- ture of 37%°C by electro-thermostat, built upon principle of unequal expansion of substances when heated; incubators are so ventilated that there is a continuous current of air within chamber, thus keep- ing temperature uniform in all working parts of apparatus; con- denser, located in base of thermostat, prevents arcing at contact points when circuit is broken, provided electric current passing through same does not exceed three amperes; maximum current consumption of models below, one ampere; provided with three shelves and one door; inside dimensions: height, 75 cm; width, 50 cm; depth, 45 cm.
