DOGS, CATS AND POULTRY 587 



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
