carbon dioxide absorbed by the eggs is given off for some time after removal 

 from the autoclave. 



The cases, after sterilization, are stored at a low temperature (o to 

 2^ C.), there being no need to make any special provision for ventilation or 

 for drying the air of the store room. On being removed from storage the 

 cases are taken to a room heated to 20" to 25° C, and when the tempera- 

 tare of the eggs has reached 7° to 8" C. (the external temperature of the 

 cases being 150 C.) the cases are opened and the eggs are packed and 

 dispatched to market. A special advantage of the method is evident 

 when the eggs are warmed, for it avoids all condensation of water on 

 the surface (a frequent source of subsequent infection) and for this reason 

 these is no immediate hurry to use the eggs after bringing them out of the 

 store room, 



Eggs which have undergone the above process are perfectly sterile ; 

 evaporation being inhibited, no loss of weight occurs ; after 10 months' 

 storage the eggs is still suitable for boiling ; the air space having remained 

 the same, no difference of any kind can be distinguished between fresh 

 and preser\^ed eggs when tested by light. The method has been in use in 

 France, Itah' and the United States either in special factories or in connec- 

 tion with ice factories.
