594 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, gruel, or arrowroot. Inject hypodermically (p. 64?:) 



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

 oz. of laudanum in water as a drench. 



Corrosive Sublimate i^Perchloride of Mercury). 



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

 Its great weight is characteristic. Abou^ a drachm and a half is 

 a poisonous dose for a horse. 



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

 mucus and blood ; skin oold 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.

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 the 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 camphor, 

 which may be repeated four or five times ; spirits and water ; or 



6 oz. of laudanum. 



Indian Hemp.
