Made to accord with rec- ommendations of Professor N, J. Giddings, of the West Virginia Experiment Station, Morgantown; incubator proper is standard, water-jacketed type, with outer air space and covered with heat in- sulating material; beneath incubator is ice chest fitted with coils of pipe, which are connected with water jacket of incubator so that water may circulate freely; in pipe line is pump, operated by elec- tric motor which is controlled by thermostatic bar, making and breaking the circuit through a solenoid switch, energized by the line, thus rendering operator independent of the troublesome dry battery; regulation is effected as easily and quickly as with ordinary electric incubator, temperature for which thermostat is adjusted re- maining constant within % °; all parts readily accessible and con- struction very simple; to put equipment into operation it is only necessary to connect feed wires and turn on current; cooling ar- rangement permits practically any desired temperature below that of room to be maintained; if temperature below freezing point is desired, cracked ice and sodium thiosulphate (hypo) are placed in ice chest, while from 4 to 12 liters of water are drawn off and re- placed by solution consisting of 50% of glycerine and 50% of alcohol (95%); by this method it is practicable to use apparatus with temperatures down to —5°C; incubator is of solid and com- pact appearance.
