 Eulenberg recommends charcoal pills for phosphorus 

 poisoning, or sulphate of copper may be given to cause 

 formation of insoluble phosphate of copper. Sulphates 

 of soda, potash, or magnesia may be given in lead 

 Doisoning with the object of forming insoluble sulphate 

 of lead. 



Among the vegetable poisons ergot of rye is one of 

 the most common. It causes trembling, vertigo, in- 

 toxication, coma, great weakness, and gangrene of the

BACTERIAL ENTERITIS. 



Inflammation of the mucous surface of the intestines 

 due to the multiplication of irritating bacteria must be 

 classed among the most common and most injurious 

 diseases of fowls. This disease occurs in chickens, 

 turkeys, ducks and probably most other kinds of birds 

 and is frequently mistaken for cholera. It is caused 

 by several distinct varieties of bacteria, and may be 

 either acute or chronic in its form. 



Causation. — The principal germs which have been 

 studied in connection with outbreaks of enteritis in 

 birds are : 



1. The bacillus gallinarum (Klein, Lucet), a short 

 bacillus found in great numbers in the intestines of 

 affected birds, and, also, in the blood. The disease 

 may be produced in chickens and turkeys by inoculat- 

 ing this germ beneath the skin. If the germs are fed 

 with ordinary food they do not cause disease, but if 

 fed with animal food the disease may be produced. 

 Fowls die in about five days after inoculation. In- 

 fection occurs from contaminated food or drinking
