POISONS. 141 



pawing and rolling; the membrane of the eye is of a 

 deep scarlet ; the saliva runs from the mouth : while 

 the purging is profuse, fetid, and sometimes will be 

 passed with blood. 



The case may not always be quite so plain ; but 

 the owner may wish to ascertain the truth or falsehood 

 of some horrible suspicion. The presence of arsenic 

 is very easily detected by chemical analysis properly 

 conducted. The process, however, is too complex to 

 be here detailed ; and the reader is therefore referred 

 to any of the many excellent works which dwell par- 

 ticularly upon this subject. 



The treatment will rarely be successful. The poi- 

 son will too frequently have done its work when the 

 symptoms become sufficiently urgent to be recognized. 

 Plenty of thin gruel or whitened water, which the 

 horse will drink with avidity, and two drachm doses 

 of opium repeated every half-hour, afford the best 

 chance of saving the animal. 



Poisoning from Corrosive Sublimate is usually 

 the result of unskilful treatment. Lotions of it are 

 employed for the cure of mange ; or for the destruc- 

 tion of vermin ; and, unfortunately, it is much more 

 easily absorbed than arsenic. Sometimes, also, the 

 animal may lick from its body a fatal portion of the 

 drug. 



The symptoms are nearly the same as those from 

 poisoning by arsenic. The remedy will consist of the 

 whites of eggs mixed with starch or gruel, and the 

 frequent administration of opium.
