582 POISONING. 



Chronic poisoning occasionally occurs among animals depastured 

 in the neighbourhood of copper-smelting works, but such effects 

 are apt in part to depend upon the arsenic present in these ores. 

 The prominent symptoms are impaired appetite, constipation, im- 

 perfect nutrition, muscular weakness, and occasionally bloody 

 urine (Finlay Dun). 



TREATMENT. — Large quantities of white of egg (raw) and 

 water, milk, gi-uel, or arrowroot. Inject hypodermically (p. 633) 

 5 grains of morphine hydrochlorate dissolved in water, or give 6 oz. 

 of laudanum in water as a drench. 



Corrosive Sublimate {Perchloride of Mercury) 



may be given by mistake for some other white powder. Its 

 great weight is characteristic. About a drachm and a half is a 

 poisonous dose for a horse. 



SYMPTOMS. — Great pain ; profuse purging ; dung mixed with 

 mucus and blood; skin cold and moist; breathing difficult. The 

 intelligence remains unimpaired up to the last. Death results 

 from failure of the heart. 



TREATMENT.— Unlimited amount of white of egg, which forms 

 an insoluble albuminate ; or gruel made with flour, arrowroot, or 

 oatmeal. Give spirits and water if depression be extreme. 



Creosote. 



See "Carbolic Acid." 



Croton. 



The oil or seeds are sometimes ignorantly given to the horse 

 as a purgative. Twenty drops of the oil, or a similar number of 

 the seeds, would probably kill a horse. 



The symptoms are those of violent purgation and inflammation 

 of tlie stomach and intestines. 



Give large draughts of soothing drink, such as gruel, white of 

 egg and water, and arrowroot; half an ounce of spirits of cam- 

 p^hor, which may be repeated four or five times ; spirits and 

 water; or 6 oz. of laudanum.
