18 IN CASES OF POISONING 



interval the animal uttering sharp, shrill, ear piercing cries, to be stifled 

 by a recurring spasm. 



Treatment;— If possible, give an emetic. This can, however, rarely be 

 done after the convulsive stage has set in. Then the dependence must be 

 on chloral hydrate, from twenty to thirty grains, administered by the rec- 

 tum. Of a mixture of this agent, (one drachm to an ounce of water), a 

 tablespoonful contains thirty grains of the chloral. After giving the injec- 

 tion, pressure should be made against the anus, to prevent its being 

 evacuated. If in twenty minutes the convulsions have not ceased, repeat 

 the injection, dose being the same. "When the convulsions are finally con- 

 trolled, allow the animal to sleep as long and quietly as possible, and when 

 he arouses up and shows a disposition to move about, give, every three or 

 four hours, one teaspoonful of aromatic spirit of ammonia well diluted, and 

 continue at intervals until perfectly conscious. 



Carbolic zicid: — Symptoms ; Great depression, trembling, shivering, 

 and loss of motion, indicative of approaching paralysis, diarrhoea, the dis- 

 charges at times bloody. 



Treatment; —Hot mustard bath, friction, and stimulants of brandy and 

 ammonia. 



IPIiosphorus: — Symptoms; Burning pain in the throat and stomach, 

 vomiting, purging, great inflammation and tenderness of the abdomen, 

 convulsions. 



Treatment; — Give promptly an emetic, followed with either magnesia, 

 chalk, or whiting in water. Avoid oils, as they dissolve the phosphorus. 



Jfercuty: — Symptoms; Acts much like arsenic, but quicker and more 

 violent, corrosion of mouth, burning of throat, distress in stomach and 

 bowels, excessive thirst, vomiting and purging of bloody mucus, skin cold 

 and clammy, convulsions. 



Treatment ; — If vomiting does not occur, induce it with an emetic ; give 

 freely white of eggs with milk, or flour and water, or flour and soft soap 

 thinned with water. The protosulphuret of iron is an antidote, but is use- 

 less ten minutes after the poison has entered the stomach. Mercury, it 

 must be remembered, occurs in many forms, the more common being 

 corrosive sublimate, red precipitate, tchiie precipitate, cinnabar, vermillion, and 

 cyanide of mercury. 



Lead Satis: — Symptoms ; Depend on the mode of poisoning. In large 

 doses, the usual symptoms are irritation, distress, and vomiting, colic, 

 constipation, cramps, and paralysis. 



Treatment ; — Give epsom salts with milk and eggs freely. 

 GENERAL ANTIDOTE — In cases of poisoning, when the nature of the 

 poison is unknown ; — calcined magnesia, powdered charcoal, sesqui oxide of 

 iron, equal parts of each in a sufficient quantity of water.
