it. The solution is thus distributed through the nostrils and other 

 canals and has an astringent and slight disinfecting action. This 

 treatment should be given twice a day and continued until all sym- 

 ptoms have disappeared. 



If there are solid tumours in the eye-lids, they should be opened 

 so that the skin may bleed freely. The cheesy matter should be 

 removed, and the surrounding membrane touched with a 5 per cent, 

 carbolic acid or silver nitrate solution, and then a cotton plug filled 

 with some antiseptic solution, put into the cavity. The cavity has to be 

 washed out daily with an antiseptic mixture, and a fresh cotton plug 

 put in again to prevent the cavity from healing too quickly. We 

 have cured chickens in this way in about a fortnight. 



As all these methods of treatment demand a great deal of time 

 and care, they cannot well be used for whole flocks, but the more 

 valuable fowls may be treated in this manner. Farmers and poultry- 

 men should first try the permanganate of potash method of treat- 

 ment as it is the easiest to employ. 



Food remedies influence roup only by strengthening the fowls 

 and assisting nature to throw off or conquer the disease. 



As in other infectious diseases, the most important thing is to 

 prevent an outbreak, or to suppress it as soon as possible. All diseased 

 fowls should be separated from the healthy ones ; and the healthy ones 

 should be examined daily, with a view to isolate newly aflfected birds. 

 After the isolation of the diseased birds, the poultry yard should be 

 disinfected thoroughly with a 5 per cent, solution of carbolic acid, 

 followed by a careful white- washing of the walls, etc. Slightly dis- 

 eased fowls, or any of special value, can be cured, if much care be 

 taken. Less valuable birds, which it will not pay to treat, should be 

 killed as soon as manifest symptoms of the disease appear, especially 

 when the face becomes swollen. These fowls, unless the best care is 

 taken, will remain diseased for months, or perhaps years, and give rise 

 to fresh outbreaks whenever an unfavorable season (with much wet, 

 cold weather) occurs. 



The most effective preventive for roup is to keep fowls in good 

 sanitary conditions — in dry, roomy yards and dry, clean, airy houses 

 which are free from draughts and can easily be cleaned and disinfected.
