title: THERMOSTAT FOR LOWER TEMPERATURES.
abstract: Details are given concerning the construction and operation of relatively simple thermostats which permit maintaining precise temperatures down to 0 degrees C. (with water), or temperatures above that of the ordinary room, and in which the temperature may be quickly altered at short intervals to new levels.
