3. SIMPLE INDIGESTION AND LOSS OF APPE- 

 TITE. 



These conditions result from such a variety of 

 causes that it is rather diiticnlt to classify them as a 

 disease. Usually they are merely symptoms of dis- 

 ease in different organs or of general disease. If, after 

 a careful examination, no cause for loss of appetite

 in large quantities and especially when the bird is un-

 detrimental and when birds are exposed to weakening 

 influences, such as sudden changes of weather, unsani-

 gest the food that they are accustomed to and have 

 been thriving upon. Or, indigestion may result from 

 feeding things that cannot be digested or that are di- 

 gested very slowly and ferment while passing through 

 the digestive canal. Putrid food of all kinds will come 

 within this class. Sometimes, foreign bodies lodge in 

 the crop or gizzard or other point in the digestive tract 

 and if they are sharp and cannot be digested or dis 

 solved, they may remain stationary for a long time, 

 causing .serious inflammation and possibly death. If 

 it is discovered that substances, such as large pieces 

 of glass, or pieces of metal, etc.. are present, they 

 should be removed by an operation similar to the oper-
