400 The Diseases of Animals 
common disease, especially when poultry is kept in 
damp and unsanitary quarters. It is due to a germ 
which may be introduced by means of diseased fowls, 
or by infected coops and pens. Good care and food 
enable birds to resist invasion by the germs, Any con- 
ditions that tend to lessen the vitality of the bird favor 
the development of the disease. 
At first, the discharge is thin and watery; but 
later it becomes thick and yellow, collecting about the 
nostrils and in the eyes and throat. The fowl is often 
unable to see, owing to the inflammation, swelling and 
collecting of matter about the eyes. As the disease pro- 
gresses, the comb and wattles become abnormally red, 
and the clogging of the nostrils and throat makes breath- 
ing difficult. Throughout its sickness, the bird is dull 
and weak, with plumage rough and erect. Finally, the 
fowl becomes unconscious and then soon dies. 
In most cases, the best treatment is to kill and burn 
the bird as soon as the disease appears. Antiseptics 
used about the head will usually overcome the disease. 
Creolin, one part to one hundred parts of water, is excel- 
lent; also, boric acid, twenty grains to one ounce of 
water; also, kerosene oil. In all cases, the mucus should 
be washed away, the parts well cleaned, and the remedy 
thoroughly applied. ) 
In the spring or fall it frequently happens that a 
number of birds are noticed sneezing and snuffing from 
eolds, with a slight discharge of mucus from the 
nostrils. For these “colds,” and as a preventive of 
roup, one teaspoonful of pure carbolic acid to one 
gallon of drinking water, is excellent.
