plant. The leaves of the first year die in the autumn. The 
leaves of the second year are large, long, and deeply inverse, 
sessile, and nearly embrace the stem, and having decurrent 
lobes, which are of a more delicate texture than the blade of 
the leaf. These lobes are important points to observe in ex- 
amining a specimen. The leaves are very clammy and fetid, 
having an odour very similar to that of the black currant; these 
are the true medicinal leaves, and they should be gathered as 
soon as the flowers are blown.

the name Henbane, but goats and swine eat it with impunity. 
Moirond (op. cit.) states that, given in large quantities to 
horses, it causes only slight dilatation of the pupil, spasmodic 
movements of the limbs, and increase of the pulse. 
On Man.—In small and repeated doses, it allays nervous 
irritability, irritation, and preternatural sensibility in any organ. 
In large doses, it causes headache, giddiness, dimness of sight, 
dilatation of the pupil, a greater or less tendency to sleep, and 
painful delirium. In some cases these symptoms are followed 
by thirst, nausea, griping, and either purging or constipation ; 
and in a few instances, febrile heat and irritation of the skin. 
Very large doses are apt to be followed by delirium rather than
