eyelids, followed by the secretion of a liquid which is 

 first clear, then gray and slimy. This either dries on 

 the feathers or becomes a yellowish cheesy mass in 

 the eye-socket. 



Combined with the above symptoms there are 

 often patches of a grayish yellow exudation firmly 

 adhering to the mouth and throat. These are called 

 false membranes, and when they are seen the disease 

 is called diphtheretic roup, which is the most serious 

 of all. 



Treatment. — The only effective treatment is 

 prevention. Housing in open-front houses, avoiding 

 drafts by carefully closing all cracks and knot-holes 

 about the roosts, keeping houses sanitary and feed 

 clean and wholesome, taking care to avoid contagion ; 

 and above all, breeding only from vigorous birds, 

 and especially from birds which have never had roup, 

 will soon do away with all fear of the disease. I 

 have not seen a case in three years, and I am satis- 

 fied that attention to the simple rules of sanitation 

 and hygiene is a sure preventive. 



Especially important is it that the ground on 

 which poultry houses stand should be well drained 

 and that houses should be dry and sunny. 



For those that feel they must treat roup, the potas- 

 sium permanganate treatment is as good as any and 

 easier than most: Press the nostrils together 

 between thumb and forefinger two or three times in 

 the direction of the beak, and press upward between 

 nostrils and eyes to loosen the discharge, then plunge 

 the bird's head twenty or thirty seconds in a one to 

 two per cent solution of permanganate of potash. 

 Give this treatment twice a day till all symptoms 

 have disappeared.
