oak-bark,
and Peruvian bark, are recommended as capable of neutralizing the
poisonous principle of mushrooms. It is however the safest way not to
eat any of these plants until they have been soaked in vinegar. Spirit
of wine, and ether, extract some part of their poison; and tanning
matter decomposes the greatest part of it.

Agaricus bulbosus.
-------- necator.
-------- mamosus.
-------- piperitus.
-------- campanulatus.
-------- muscarius.

These are kown to be poisonous. But the fungi should all be used with
great caution; for I believe even the Champignon and Edible mushroom to
possess deleterious qualities when grown in certain places.

SECTION XIV.--PLANTS NOXIOUS TO CATTLE.

The foregoing lists of poisonous plants are most of them of less
dangerous tendency to cattle than to the human species: for although
many of them may be mistaken for wholesome, yet, when they are growing
wild, it will be observed, that the discriminating powers of the brute
creation in this point are so correct, that very few have been known to
be eaten by them.

The following are a few of a different class, which, as not containing
any thing particularly disagreeable to the taste of cattle, are
frequently eaten by them to their injury.

The agricultural student should make himself perfectly acquainted with
those.

652. CICUTA virosa. COWBANE.--Linnaeus observes, that cattle have died in
consequence of eating the roots. It is fortunate that this plant is not
very plentiful: it is poisonous to all kinds of cattle except goats. The
flower of this plant is not unlike that of water-parsneps, which cows at
some seasons will eat great quantities of.

653. BEAR'S GARLICK. Allium ursinum.

654. CROW GARLICK. Allium vineale.

These plants very frequently occur in meadow-land, and have property of
giving a strong garlick flavour to the milk yielded by cows that feed
there; and which is often also communicated to the butter.

655. DARNELL GRASS. Lolium temulentum.--This grass has the faculty of
causing poultry or birds to become intoxicated, and so much so that it
causes their death.

656. LOUSEWORT. Pedicularis palustris.--This plant, which abounds in wet
meadows, is said to produce a lousy disease in cows if they eat of it.

657. MAYWEED. Anthemis cotula.--This is altogether of such an acrid
nature, that the hands of persons employed in weeding crops and
