would cause its death. The best means of preventing 

 this disease is to use a mild astringent in the drink- 

 ing water several times each week. Alum I have 

 found the best for tliis purpose, but it must be used 

 very judiciously. 



WING PARALYSIS. 



Cause: No direct cause can be attributed to 

 this disease, but it is often seen associated with dis- 

 turbances of the Liver, especially that of congestion. 

 It can also be caused by lead poisoning, the bird 

 having drank water occasionally out of old paint 

 cans or of water standing a long time in leaden 

 vessels or pipes. Wing Paralysis or dropped wing 

 will often be found in the debilitating diseases where 

 there is extreme weakness. It may however, be 

 caused also by an internal disease of one of the other 

 vital organs, such as Congestion of the Lungs, etc., 

 and is sometimes seen in birds suffering from severe 

 atony of the crop. 



Symptoms: The wing or both wings appear 

 powerless and drag upon the ground. There is gen- 

 erally in true paralysis no swelling, stiffness, etc., 

 but if anything, there will be a somewhat emaciated 

 condition of the wing. 



Treatment: As Paralysis of the Wing is merely 

 a symptom of some other disease, it is the main 

 point to make a true diagnosis, and treat the cause 

 rather than commence treatment upon the wing itself. 

 If it be the cause of liver troubles as above men- 

 tioned, then follow the treatment adopted for that 

 complaint, if from weakness from a debilitating 

 disease use a tonic, or if from crop disease use that 

 treatment, but to make a permanent cure the cause
