DISEASES OF THE DIGESTIVE TRACT 131 



purplish red. There was slimy mucus in the mouth. The general 

 condition of the plumage was fairly good. The carcass had a fair 

 amount of fat on it. The liver appeared dark, but normal in size. 

 The gall-bladder was full of bile. The peritoneal surfaces were 

 covered by a mildew-like material. The carcass was cold due to 

 the fact that it had been in refrigeration over night. This mildewed 

 condition may have been due, in part, to this cause. The spleen 

 was normal in size and appearance. The intestines appeared normal 

 except for the above described condition. Ingesta and a small 

 amount of gas were contained in the intestines. The ceca and 

 large intestines contained a small amount of ingesta. The pancreas 

 appeared normal. The kidneys were of a light mottled grey, the 

 anterior lobes appearing swollen and highly congested — apparently 

 blocked with the pasty, white urinary secretions. There was 

 present cloudy swelling. The ureters were distended with urinary 

 secretions of a pasty nature. The ovary was inactive and of a 

 pinkish color. The accumulated material of the right ureter was 

 thinner and more slimy than the left, and upon a microscopic ex- 

 amination, was found to be teeming with short, chained, strep- 

 tococci; pus cells of both mononuclear and polymorphonuclear 

 varieties and sodium urate crystals were present. There was about 

 5 cc. of a thin, milky liquid in the peritoneal cavity. The strep- 

 tococci seemed to be confined to the abdominal region affected with 

 purulent inflammation. Microscopic examination of the pleural 

 fluid, lungs, blood and heart blood revealed nothing abnormal. 



A microscopic examination of sections from the kidneys stained 

 with hematoxylon and eosin showed both active and passive con- 

 gestion, with cloudy swelling. There were pus cells and hemorrhage 

 into the collecting tubules. Areas here and there showed localized 

 nephritis as evidenced by the area being packed with polymor- 

 phonuclear and mononuclear leukocytes, similar to those found in 

 the peritoneal exudates. 



INTESTINAL DISEASES OF CANARIES 



Intestinal troubles in canaries are usually due to errors in 

 feeding and watering. In diarrhea remove all green feed and 

 do not give any soft feed. Give just the normal seed supply. 

 Feed the bird with a small piece of wet bread on which has 

 been sprinkled subnitrate of bismuth. If the case does not 

 yiekl to this treatment place in the drinking cup one ounce 

 of clear water in which has been placed four drops tincture 

 of opium and fifteen drops whisky or brandy. 



In case of constipation give plenty of green feed such as 

 Jettuce, apph\ chick weed. Add a pinch of Epsom salts to the 

 drinking water. IMake the water so that it has a faintly saline 

 taste of the Epsom salts.
