f any vegetable in
common use likely to be confounded with this. It might by chance be
mistaken for the smaller tubers of Jerusalem artichoke.

In foliage it comes near to the other species of Aconitum, and to the
perennial Larkspurs.

However, as this is a plant much grown in pleasure-grounds on account of
its beautiful blue flowers, great care should be taken not to use any
roots taken from such places that cannot be well ascertained.

629. ACONITUM Lycoctonum. YELLOW WOLFSBANE.--Every part of this plant is
accounted poisonous. In fact, I think it is proper that all the species
should be considered as such, and never be made use of, either in
medicine or otherwise, without great care in their administration.

630. ACTAEA spicata. BANEBERRY.--This plant is also considered as a
deadly poison; but we have no authentical accounts of its mischievous
effects, although Parkinson has mentioned it in these words:--

"The inhabitants of all the mountaines and places wheresoever it
groweth, as some writers say, do generally hold it to be a most
dangerous and deadly poison, both to man and beast; and they used to
kill the wolves herewith very speedily."

This is not a common plant, growing only in some particular situa-tions,
as near Ingleborough in Yorkshire.

631. RHUS Toxicodendron. POISON-ASH.-The juice of the leaves of this
plant is so very acrid as often to corrode the skin, if the leaves are
gathered when the dew is on them. Great care should certainly be taken
in the giving such a medicine internally, as also in its preparation, it
being usually administered in a dried state.

Planta affinis.

Rhus radicans differs from this in having a more trailing habit of
growth; otherwise it is scarcely different, so little so, as to baffle a
distinction being made by description alone.

STUPEFYING POISONS.

The substances that deaden the effects of the poisons of this class are
vegetable acids, which should be thrown into the stomach in large
quantities. After the operation of emetics, cream of tartar is also
considered of great use, as also oxymuriatic acid, infusions of
nut-gall, oak bark; warm spices are considered also of use, for they may
separate some part of the deleterious matter, as is shown by their
effect when mixed with decoction of these plants; acerb and astringent
wines are also of great use.

632. AETHUSA Cynapium. FOOL'S PARSLEY.--Fool's
