 INCUBATORS FOR HEATING BY ELECTRICITY. 



296 s Incubators with electrical heating and regulating arrangement for 37 C. The heating 

 resistance is wound on and enclosed in mica plates, and are not liable to get out of order. 

 The mica plateswith resistance are inserted into narrow pockets in chamber of Incubator, 

 and can be easily removed as required. A metallic capsule with a fixed boiling point 

 controls the temperature by actuating on an arrangement which cuts off current to heating 

 resistance immediately the desired temperature is reached, and on a slight fall in tempera- 

 ture the heating resistance is again automatically brought into connection with current. 

 The Incubator is made throughout of hard rolled copper and incased in polished oak, with 

 uralite panels well insulated to insure uniformity of temperature throughout chamber, and 

 to prevent loss of heat. Capsules supplied with higher or lower boiling points if required, 

 each suitable for a range of 4 C.
