Constructed of heavy asbestos wood, with cast aluminum door and door frame; air space between inner and outer walls is filled with insulating material; interior is fitted with aluminum racks, allowing the perforated metal shelves to be placed at any desired height; has an inner door of heavy glass, fitted in an aluminus frame, cushioned with felt to exclude the air, permitting inspection of the chamber without disturbing the temperature; has opening through top for a thermometer and two snap switches, one for the current and one for lamp illuminating the chamber; supplied with flexible cord and plug to fit ordinary lighting circuit, and high- grade thermometer of special design, with graduations to 70°C; pre- sents following advantages: 1. Accuracy of "all metal" regulating device, which maintains con- stant temperature to fraction of a degree; continuous test at 37% °C for forty days showed fluctuations of temperature to be scarcely perceptible. 2. Ease of setting for the temperature desired, requiring but a few seconds of time; accomplished by simply turning a milled-head screw, which moves indicator up or down the graduated tem- perature scale. 3. Absence of complicated devices for heating, regulation, etc.; rugged construction of all parts is such that, with ordinary care, no parts are likely to get out of order. 4. Water is not required, nor employed, to maintain even tempera- ture throughout chamber, thereby eliminating leakage. 5. No auxiliary devices needed; to operate, it is only necessary to screw the plug into a lamp socket and turn on the current; oper- ates on either direct or alternating current. Incubator is of durable and handsome construction; mounted on heavy iron stand base with legs; dimensions: height, 62% cm; with, 10
