der is, as a rule, empty. In the digestive tract we observe frequently yellovirish 

 discoloration of the mucosa, hemorrhages in the small intestine with catarrhal 

 lesions of the entire canal. The heart is pale and friable and the blood which

Treatment. This is chiefly preventive since there is no specific antidote. 

 Attempts should be made at once to prevent further absorption of poison by 

 administering some acid as acetic or hydrochloric, well diluted with water. 

 Alkalis should be strictly avoided as the poisonous principle is very soluble 

 in alkaline solutions. It is advisable to evacuate the bowels by giving a purga- 

 tive, preferably oil. Potassium permanganate is recommended by some as an 

 antidote. Further than this the treatment is entirely symptomatic. (Stuhr).
