DISEASES OP THE DIGESTIVE ORGANS. 43 



or after the fowl has been exposed, and lasts from 

 one to three days. 



The most reliable methods of diagnosing cholera 

 are its rapid spreading through a flock, showing its 

 highly contagious character; its being very fatal in 

 a few days; the greenish diarrhoea; upon examin- 

 ing a dead fowl the internal organs are nearly all more 

 or less involved; the liver, kidneys, heart and spleen 

 are often found swollen, red or congested; the bowels 

 show patches of congestion and inflammation and 

 occasionally the lungs will be found engorged. 



Prevention: Because of cholera being due to 

 germs and therefore infectious, all efforts possible 

 should be put forth to prevent its spreading, by such 

 mediums as explained above, and where there is an 

 outbreak the sick should be isolated from the well, 

 the premises cleaned and disinfected at least twice a 

 week by washing the floors and roosts with a carbolic 

 acid solution, one pound dissolved in three gallons of 

 hot water, and, if possible, the walls whitewashed. The 

 droppings and dead birds should be burned daily. The 

 drinking water should be previously boiled and given 

 in vessels that are scalded and cleaned each day. 

 Feeding and watering should be done through a slat- 

 ted partition to prevent carrying infection on the food 

 and water with their feet. 



For those that are not yet afflicted, a teaspoonful 

 of dilute sulphuric acid may be added to each quart 

 of drinking water once a day.
