686 TOXICACEOUS HERBS. 



The Foxglove (Digitalis purpurea, L.) is a scrophularinaceous bien- 

 nial, a native of Britain, and common in copse-woods and hedge- 

 wastes. The whole plant is poisonous, and may be used for the same 

 purpose, and in the same manner, as the tobacco. 



The Henbane (Hyoscyamus niger, L.)) and the Thorn-apple (Datura 

 Stramonium, L.), are well known indigenous annuals, of highly nar- 

 cotic properties, which, if treated like the tobacco, would probably be 

 equally efficacious in the destruction of insects.
