ike gum arabic. The nut or
fruit contains a black, acrid, caustic oil, injurious to the lips
and tongue of those who attempt to crack the nut with their teeth;
it becomes innocuous and wholesome when roasted, but this process
must be carefully conducted, the acridity of the fumes producing
severe inflammation of the face if approached too near.

27. ANANASSA SATIVA.--The well-known pineapple, the fruit of which was
described three hundred years ago, by Jean de Lery, a Huguenot
priest, as being of such excellence that the gods might luxuriate
upon it, and that it should only be gathered by the hand of a
Venus. It is supposed to be a native of Brazil, and to have been
carried from thence to the West, and afterwards to the East
Indies. It first became known to Europeans in Peru. It is
universally acknowledged to be one of the most delicious fruits in
the world. Like all other fruits that have been a long time under
cultivation, there are numerous varieties that vary greatly, both
in quality and appearance. The leaves yield a fine fiber, which is
used in the manufacture of pina cloth; this cloth is very
delicate, soft, and transparent, and is made into shawls, scarfs,
handkerchiefs, and dresses.

28. ANDIRA INERMIS.--This is a native of Senegambia. Its bark is
anthelmintic, but requires care in its administration, being
powerfully narcotic. It has a sweetish taste, but a disagreeable
smell, and is generally given in the form of a decoction, which is
made by boiling an ounce of the dried bark in a quart of water
until it assumes the color of Madeira wine. Three or four grains
of the powdered bark acts as a powerful purgative. The bark is
known as bastard cabbage bark, or worm bark. It is almost obsolete
in medicine.

29. ANDROPOGON MURICATUS.--The Khus-Khus, or Vetiver grass of India.
The fibrous roots yield a most peculiar but pleasing perfume. In
India the leaves are manufactured into awnings, blinds, and
sunshades; but principally for screens, used in hot weather for
doors and windows, which, when wetted, diffuse a peculiar and
refreshing perfume, while cooling the air.

30. ANDROPOGON SCH[OE]NANTHUS.--The sweet-scented lemon grass, a native
of Malabar. An essential oil is distilled from the leaves, which
is used in per
