In =verminous thrombosis=, to the symptoms just named there are added the reckless method of throwing himself down, hyperthermia, constancy of the pain, rapidly running down pulse, cold sweats, and profound prostration. When blood is passed per anum it is all the more significant. In =enteritis= or =peritonitis= the hyperthermia and the constancy of the pains are sufficiently pathognomonic. In =intestinal anthrax= there are the dusky brownish yellow mucosæ, the marked prostration, the hyperthermia and the constancy of the suffering. There is also the fact that the region is subject to anthrax and bacilli may be present in the blood. In =acute hepatic disease= there is hyperthermia, dusky or icteric mucous membranes, great tenderness when percussion is made over the short ribs, and sometimes lameness of one shoulder (usually the right). In =disease of the urinary or generative organs= the stiff or straddling gait, tender loins, and the frequent stretching as if to urinate, are nearly pathognomonic. In =pleurisy= the hyperthermia, the transient duration of the colic, and the tenderness on manipulating the intercostal spaces will usually differentiate. =Ruminants.= In cattle, as in the horse, the symptoms of spasmodic colic are restlessness, constant movement, looking round at the flanks, wriggling of the tail, uneasy lifting of the hind feet, kicking at the abdomen, and abruptly lying down and rising again. The animal does not roll on the back nor sit on the haunches. Fæces may be passed in small quantity or entirely suppressed, and there may be a slight tympany of the paunch. =Swine.= The animal is attacked abruptly, starts with a grunt or scream, moves around uneasily, lies down, rolls, gets up, and repeats the motions. Vomiting is not uncommon, and the belly may be tense, tympanitic and even tender. The bowels may be confined or relaxed. =Carnivora.= The colicy dog is very restless, changing from place to place, sitting on his haunches, lying down curled up, starting up suddenly with a yelp, and repeating the restless movements. He looks anxiously at his flank, sometimes bites at it, and cries plaintively. The bowels are usually torpid, and defecation effected with straining. There are distinct intermissions but these are cut short by a new accession of pain. The attack is usually transient and ends in recovery.
