The system which was found tobe the most practical w as finally employed in the man-ufacture of the Cyphers Incubators. The porous dia-phragms form the upper and lower divisions of thechamber, and through them the air has to pass inentering anil leav ing the egg chamber. The fresh warm air is first distributed evenly overthe whole area of the upper diaphragm before enteringthe hatching chamber, and after diffusing through theminute pores the air is gradually forced down aroundthe eggs and through the chamber in a slow but pos-itive manner. It is there diffused through anotherporous diaphragm placed above a shallow chamber inthe bottom, whence it is forced out into the heater,carrying with it the poisonous gases thrown off by theeggs, and is dissipated in the outer air. This methodgives a larger volume of pure air than is employed inother machines, and without the drying effects ofprofuse direct ventilation. 23. CONSTRUCTION OF THE CYPHERS INCUBATORS ; MATERIALS USED. The heater is so arranged that the fresh air gainsmoisture as it gains warmth, and by the time it entersthe egg chamber its relative humidity is equal to thatof the outer air. Thus, in the Cyphers, the tensionof the moisture around the eggs is always equal to that,out of doors, as is the case with the hen upper and lower diaphragms keep the air fromentering and leaving at one point, thus diffusing it overthe entire area of the chamber ; while the rarefactionof the air in the heater keeps the downward movementthrough the egg chamber positive, though slow. Theeggs arc never dried down too much, though they aresupplied with an abundance of fresh air, enabling usto run ha
