human. The mouth smells sour. As a result there will be a 

 lowering of temperature, i. e., subnormal. The amount of the 

 fall of temperature depends upon the nervous prostration which 

 results from the evacuations. The mucous membranes become 

 blanched and they become paler as death approaches ; tlie pulse 

 gets small, weak and hard; animal has a dejected appearance; 

 he sometimes sweats in patches, as death approaches ; ultimately 

 he dies from syncope, or collapse. 



Diarrhoea runs a very rapid course; in young animals 6-10 

 hours may be fatal. In case of superpurgation ( an overdose or 

 injudicious repetition) the course is very rapid. Do not repeat 

 a dose of aloes under seven days, for you are liable to get serious 

 results. Be very careful about repeating purgative doses. Some 

 say that oil will kill a horse. 'T know better." You can give 

 him a gallon in some cases when needed. It is better to let the 

 horse die from other trouble than from superpurgation. 



The bowels of the horse are very sensitive ; I do not believe 

 in severe purgation for it is weakening. The danger lies in 

 injudicial repetition of the dose. 



The strongylus tetracanthus sometimes sets up an enteritis 

 rather than a diarrhoea. 



In all cases where the temperature runs down, the surface 

 gets cold, especially in young animals. Foals shut up from their 

 mothers should not be separated for more than four hours, for 

 the milk will spoil and produce diarrhoea in the foal. Let the 

 colt suck some every four hours. Never overheat a mare 

 suckling a colt; for this produces an unthrifty condition of the 

 colt. 



Post mortem. — General pallor ; the mucous lining of the bow- 

 els is pale ; intestinal epithelium eroded in places over extensive 

 areas ; may find inflammation ; peritoneal coat spotted ; ecchy- 

 mosis ; contents of the rectum more or less bloody, called by 

 some dysentery, but it is really bloody diarrhoea. In dysentery 

 we have a rise of temperature ; in diarrhoea, a lowering. 



Treatment. — Remove the cause. For the excessive peris- 

 talsis opium is the only remedy; for the acid condition of the 

 bowels give antacids. If the fermentation is microbic, give anti- 

 septics. Salol is the best ; it is effectual and harmless. Opium
