They consist in dulness, lassitude, loss of appetite, nausea, flatulence, diarrhoea, infrequent, full pulse (reduced 6-10 beats in the horse), and contracted pupils. There is vomiting in dogs. In fatal cases these symptoms are followed by severe colic and tympanites; rapid, feeble, dicrotic, irregular or intermittent pulse (120-140 in horses), while the heart may be heard and felt beating wildly and strongly, and a systolic blowing murmur can frequently be detected. This is due to or tricuspid regurgitation caused by ir- regular contraction of the columns cams. The pulse is imperceptible because of the failure of the heart to fill the vessels. The extremities are cold, the eye is protruding, and salivation occurs. Bloody diarrhoea is very often present and the urine may be suppressed. The breath- ing finally becomes difficult and death ensues within a few hours, or as late as several days. Treatment.âEvacuation of the stomach and bowels.
