* (As several plants of this Class are powerfully deleterious, it may be here stated, that 
the most prudent and effectual domestic treatment to arrest the progress of vegetable poi¬ 
son, (where medical aid or the use of the stomach pump cannot be promptly obtained), is 
to excite vomiting by repeated doses of salad or sweet oil, or hour of mustard, with warm water, 
followed by a moderate quantity of vinegar or lemon-juice, and purgatives. Some valuable 
remarks on this important subject, with a perspicuous tabular view of vegetable poisons, 
their symptoms and treatment, will be found in the Popular Lectures of W. Lempriere, 
M.D. 8vo. 1827* It is a curious fact, lately ascertained by M. Morcet, that these poisons 
prove equally destructive of vegetable, as of animal life. Bean plants, which will continue to 
live several days in spring water, were quickly killed by the infusion of a few grains of 
opium in an ounce of water in which they were immersed. Hemlock produced similar 
effects ; and six grains of powdered Fox-glove, in an ounce of water, exhibited its dele¬ 
terious effects by wrinkling the leaves of the plants in a few minutes, and destroying them 
in twenty-four hours, E.)
