One of the most common diseases of the air passages is catarrh (cold). It is often hard to distinguish this disease from early stages of roup and diph- theria. The characteristic symptoms of the latter dis- ease should be carefully looked for, lest the flock become infected with a dan- gerous contagious disease. In cases where there is a suspicion of either of these diseases it is better to iso- late the sick birds. Catarrh is non-contagious. It usu- ally affects only a few indi- viduals in the flock, but in cases of exposure of the flock to the unfavorable conditions which cause the disease it may occur in quite a number of birds at the same time. Diagnosis. Salmon gives the following description of the symptoms of this disease: "In simple, non-contagious catarrh, the affected birds are more or less dull, they are disinclined to move, their appetites are diminished, they sneeze and the mucous membrane is thickened, causing some obstruction to breathing through the nostrils. There soon appears a thin, water dis- charge which later becomes thicker and glutinous, the eyes are often watery, the eyelids swollen and sometimes held together b}' a thick, viscid secretion. In very severe cases, the birds are somnolent, the plumage is erect and roughened, the nostrils are completely obstructed by the thick secretion, the breathing is entirely through the mouth and is accompanied by a wheezing or snoring sound, the appetite is entirely lost, a thin liquid es- capes from the mouth and the bird soon becomes exhausted and ; Fig 14 A.—Lobule of the lung of a bird represented in ideal longi- tudinal section; a, a, secondary ; b. b. tertiary bronchi.
