DCKJS, CATS AND POULTRY 
Causes. — It is caused by small germs or parasites get- 
ting into the system and affecting the head. When one 
turkey becomes affected it generally spreads through the 
whole flock. 
Symptoms. — The first symptom noticed is swelling 
around the head, usually in front of the eyes. In some cases 
the swelling only affects one side of the head, and develops 
until it closes the eye right up, and the turkey goes around 
with its head to one side. In other cases both sides become 
swollen at the same time, and closes both the eyes. Al- 
though these swellings are mostly in front of the eyes, they 
may affect other parts of the head, and even the feet in some 
cases. If not treated, it gradually increases- around the head 
until it works into the throat and kills the turkey. If in the 
foot, it swells and becomes so bad that it finally dies. 
Treatment. — When this disease gets into a flock of tur- 
keys, if not treated it kills nearly all the members of the flock 
before it stops. Separate the diseased turkeys from the sound 
ones, and give to a medium-sized bird three drops of spirits
