There is colic, nausea, retching, vomiting of septic or bilious 

 matter, ardent thirst, dry mouth, furred tongue, redness of the 

 buccal mucosa, and tenderness of the abdomen. Diarrhoea sets 

 in early and may become bloody, foetid and dysenteric. There 

 is usually much prostration and debility so that apart from his 

 compulsory' movements inider the colics the animal remains most 

 of the time cui'led up. Fever is usually slight but the tempera- 

 ture may rise to 105° F. Death may take place in 3 hours, or 

 may be deferred 24 hours or longer. 



Lesiofis. There is usually gastroenteritis, the mucosa being 

 congested, red oedematous, with petechise, and congestion and 

 swelling of Peyer's patches, the solitary glands, the mesenteric 

 glands, the liver and kidneys. The contents of the bowel are 

 browni.sh red, and an effusion into the peritoneum is common. 

 The .spleen is often engorged and enlarged. Congestions of the 

 lungs and brain are common. 



Treatment. Evacuate the stomach by ipecacuan, etc., and the 

 bowels by a purgative. Next seek elimination of the toxins by 

 potassium iodide and other diuretics. Antiseptics (calomel, salol, 

 naphthalin) to counteract the further formation of toxins, and 

 demulcents hy draught and enema are indicated. In cases of 

 great prostration, heart and nerve stimulents may be useful.
