discharge from the nostrils, and a slight swelling of the eyelids ; in worse 
cases the face is swollen at the sides, and the disease appears to pass on into 
true roup. 
Causes . — The cause is exposure to cold and dampness, such as a long con- 
tinuance of cold wet weather, or sleeping in roosting-places open to the north or 
east. 
Treatment . — In simple cases, removal to a dry warm situation, and a supply of 
food rather more nutritious and stimulating than usual, soon effect a cure. I 
have found a little mashed boiled potato, well dusted with common pepper, very 
advantageous. In severe cases, the disease so closely resembles roup, that it may 
be treated in the same manner. 
BRONCHITIS. 
Symptoms . — If the cold, to use a popular mode of expression, settles on the 
lungs, instead of affecting the head, the symptoms are somewhat different ; there 
is rattling in the throat, from the accumulation of mucus, which the fowl coughs 
up and expectorates at intervals. 
Treatmeiit . — Kemoval to a drier habitation is sufficient in almost all cases to 
effect a cure. 
ROUP. 
Symptoms . — The symptoms of roup are at first identical with those of a severe 
catarrh ; the discharge from the nostril, however, soon loses its transparent 
character, becoming more or less opaque, and of a very peculiar and offensive 
odour ; froth appears in the inner corner of the eye ; the lids swell ; and in severe 
cases the eye-ball is entirely concealed ; the nostrils are closed by the discharge 
drying around them, and the eyelids are agglutinated together ; the diseased 
secretion accumulates within to a great extent, consequently the sides of the face 
swell to an extreme degree, and the bird, unable to see or feed itself, suffers from 
great depression, and sinks rapidly. 
Koup is essentially a disease of the lining membrane of the nasal cavities. 
This being inflamed, becomes swollen, and secretes the discharge before mentioned. 
These two circumstances combined tend to close up the small external aperture of 
the nostrils : as fowls habitually breathe through the nose, the mouth being kept 
closed, it follows that there is even in the early stages some difficulty of breathing, 
and a distension of the loose skin below the under-jaw may be often noticed. The 
frothy matter appearing at the corner of the eye results from the same cause ; the 
air, stopped in its passage through the nose, passes up the tear duct, leading from 
the eye to the nose, and produces the appearance of bubbles in the corner of the 
eye. In very severe cases the cavity of the nose becomes filled with the diseased 
secretion, which cannot escape, owing to the small size and closure of the nostril, 
and then the face swells considerably. 
With respect to the communication of this disease, my experiments prove that
