 the outer membranes and shell. 



A double egg is an tgg within an egg and is formed when 

 the original egg by some cause is forced back into the oviduct. 

 A new layer of albumen is formed around it and, as it passes 

 onward, a new shell is formed. Thus we have the strange 

 phenomenon of an egg within an egg, an egg with two layers 

 of albumen and two shells. 



Wormy eggs are caused by the passage of worms from the 

 cloaca into the oviduct, where they become enveloped by the 

 albumen before the shell is formed. 



Stale fresh-laid eggs, which are foul in odor and offensive 

 in taste, may be traced to individual hens and may be due 

 either to the feed consumed or to a diseased condition of the 

 egg organs. 



Gangrene or vent gleet of the cloaca, inflammation of the 

 oviduct, or a disease of the ovary might account for this con-

 of sufficient ash, hens will eat their own droppings, and this
