TOXIC GASmO-ENTEBITIS. 



229 



Autopsy. Lesions of corrosive gastro-enteritis ; sometimes 

 stomatitis and pharyngitis. 



Treatment. Mucilages and opium are to be given ; later stimu- 

 lants must be used. 



Poisoning may be produced by croton seed as well as by the oil. 

 It is rare to see poisoning produced by cutaneous absorption ; this 

 most frequently results from errors made by administering the drug 

 in too large doses. Fatal doses : for the horse, 20 drops j for the 

 ox, 40 drops ; for the sheep, 15 drops ; for the dog, 5 to 10 drops. 



17. Poisoning by Euphorbia {Euphorbia lathy ris). 



Symptoms. They are colic, constipation, abundant and bloody 

 diarrhea ; hematuria, tympanites ; the pulse is light, the heart 

 tumultuous. We observe stupor in the ox and sheep. 



Autopsy. Lesions of acute gastro-enteritis. 



Treatment. Symptomatic. 



18. Poisoning by Mercurialis annua et perennis. 



Symptoms. Gastro-enteritis, hematuria, strangury, sensitive 

 # condition of the region of the kidneys ; accelerated respiration, 

 tremblings ; small, accelerated pulse. 



In one case the symptoms appeared ten minutes after the inges- 

 tion of the plant. 



Autopsy. We find lesions of gastro-enteritis and nephritis. 



Treatment. Symptomatic. 



H. Schulz has made experiments in feeding pigs and rabbits 

 with Mercurialis perennis ; none of these animals died. The urine 

 showed a red coloration, but this was not due to coloring matters 

 of the blood. The urinary secretion was considerably increased, 

 the bladder much distended (paralysis of the bladder), and its 

 neck was spasmodically contracted. The intestinal functions were 

 diminished. 



19. Poisoning by Daffodils (Narcissus poeticus et N. pseudo- 

 narcissus). 



Symptoms. Intense gastro-enteritis, abundant diarrhea; stupor 

 and weakness ; convulsions and spasms. 

 Autopsy. Lesions of gastro-enteritis. 

 Treatment. Symptomatic. 

 The stem and bulbs are poisonous.
