Vegetable Narcotic Poisons. 49 



One of these dogs I opened in his sleep, and found a 

 greater redness in the tissues than usual, such how- 

 ever as I had previously seen in the human body after 

 poisoning by chloroform. 



Liebreich said, chloral hydrate injected beneath 

 the skin yields nascent chloroform by action of the 

 alkali of the blood, and produces narcotic effects. 



These experiments go a long way to confirm his 

 view.
