This disease may, also, re- sult from the inhalation of irritating vapors, dust, and other foreign substances. A careful discrimination should be made between bronchitis arising from such causes and that due to contagious catarrh (roup), tuber - culosis, gape worms, and the aspergillus fungus. Symptoms.â The birds are some- what dull, with loss of ap])etite, ac- celerated breathing and cough. On listening to the respiration a blow- ing or whistling sound may be heard in the air tubes, in the early stages of the disease, caused by the air lieing drawn over the dry and thick - ened membrane; later, a rattling oi bubbling sound is heard caused by air passing through accunuilations of mucus. In the majority of cases the symptoms are not serious, and, under favorable conditions, they soon disappear. Occasionally, the malady increases in intensity, the ])lumage becomes rough, the wings droop, the breathing is labored and difficult, the bird frequently opens its beak in order to obtain sufliicient air, it is sbepy, torpid and exhausted. In such severe forms of the disease a large proportion of the affected birds die. Treatment.â The first indication in simple bron- chitis is to place the affected birds in a comfortable, dry and reasonablj^varm place, where the}^ will not be subjected to draughts of air, but where the ventilation is good. Give soft and cooling food, such as stale bread^.
