Roup Symptoms and Treatment 339 



the nostrils, followed by obstructed breathing. A 

 few cases of harsh breathing that had not pre- 

 viously been manifest should be looked upon with 

 suspicion. These cases may be readily detected 

 by passing through the poultry house in the eve- 

 ning when all is quiet. In the later stages of the 

 disease the watery discharge at the nostrils becomes 

 thicker and more sticky, which causes frequent 

 sneezing in order to prevent the air-passages from 

 becoming completely closed. 



Dr. D. E. Salmon says* that the inflammation 

 extends, as the disease advances, from the mem- 

 brane of the nasal cavities to those of other con- 

 necting passages. As the orbital space which sur- 

 rounds the eye connects with the nasal passage, 

 this is frequently involved. The membrane of 

 the orbital cavity becomes inflamed and swollen, 

 and in severe cases apparently forces the eye from 

 its socket. The sides of the head become unduly 

 swollen and the fowl frequently becomes entirely 

 blind, the birds presenting a most unsightly appear- 

 ance. Breathing is performed with difficulty, and 

 a thick discharge at this time, may escape from 

 the nostrils. Death frequently follows after these 

 serious symptoms. 



Treatment. Prevent healthy birds from becom- 

 ing contaminated by removing them to clean 

 quarters, or by the removal of the sick birds and
