 are killed or, at least, the diseased products which are discharged are 

 removed, and the irritation caused by them ; also the transformation 

 into large cheesy masses is prevented. 



We had chickens badly affected with roup of the eyes, which 

 were cured with boracic acid and chamomile. On account of the small- 

 ness of the nostrils and nasal canals, it is very difficult to get the 

 antiseptic solutions into the nose and nose cavities ; but it can be done 

 with a small syringe. If this treatment is too troublesome, then the 

 nostrils, at least, should be washed and opened several times a day, to 

 allow the secretions to pass away. We have treated chickens for 14 

 days by daily washing with a 2| per cent, solution ot creolin and 

 glycerine. After the washings, small plugs of cotton wool, filled with 

 mixture, were placed in the nostrils and lachrymal ducts. This remedy 

 did not cure the roup in the head, although the same mixture readily 

 kills the roup bacillus in cultures in from 2 to 3 minutes. The great- 

 est hindrance to a sure cure by remedies which have been used locally, 

 is the ability of the germ to penetrate into the tissue and the many 

 secondary cavities of the nostrils which cannot be reached by the 

 antiseptics.

Another method of treatment which gives excellent results, 

 especially in the earlier stages of roup, is the use of a 1 to 2 per cent, 

 of permanganate of potash. Fowls are treated in the following 

 manner : the nostrils are pressed together between thumb and fore- 

 finger in the direction of the beak two or three times. Pressure 

 should also be applied between nostrils and eyes in an upward direc- 

 tion. This massage helps to loosen the discharge in the nostrils and 

 eyes. The bird's head is then plunged into the solution of permanga- 

 nate of potash for twenty or thirty seconds, (see Fig. 10) in fact the 

 head may be kept under the solution as long as the bird can tolerate
