Use the sulphate of Magnesia for this purpose or 

 Castor Oil, after which the best attention possible 

 must bo given in the way of feeding, allowing the 

 bird nothing that has a tendency to scour. Rye is 

 often used as pigeon feed, and is one cause of so 

 much diarrhoea. When the cause is from a liver 

 complaint give the phosphate of soda. Enteritis 

 caused by worms will be described under Intestinal 

 Worms. 



INFLUENZA, (or Catarrh.) 



Influenza is an infectious disease characterized 

 by great prostration and a more or less catarrhal 

 condition of the mucous membranes, particularly those 

 of the throat and respiratory organs. The intestines 

 are also sometimes affected by the catarrh. Com- 

 plications such as Pneumonia may arise in this dis- 

 .ease and the delicate birds are more subject to this 

 complication than the more robust. It is an exceed- 

 ingly contagious disease and may be contracted to 

 healthy birds from the sick ones. The bacillus of 

 this disease are present in enormous numbers in the 

 head and throat of the afflicted birds. The period of 

 incubation is about from two to four days and un- 

 complicated cases usually recover, but delicate birds 

 and their young often die from the disease itself, or 

 from the extreme weakness following. Influenza is 

 caused by a peculiar miasma in the atmosjAere and 

 is usually epidemic afllicting many birds in the whole 

 community at the same time. 



Symptoms: Fever; eyes are swollen, watery and 

 inflamed. A gummy, sticky discharge will run from 

 the nostrils and from the mouth, collecting, as it 

 were, upon the sides of the mandible or bill. The
