which yields the tallow. This is obtained by first steaming the
seeds, then bruising them to loosen the fat without breaking the
seeds, which are removed by sifting. The fat is then made into
flat circular cakes and pressed, when the pure tallow exudes in a
liquid state and soon hardens into a white, brittle mass. Candles
made from this get soft in hot weather, which is prevented by
coating them with insect wax. A liquid oil is obtained from the
seeds by pressing. The tree yields a hard wood, used by the
Chinese for printing blocks, and its leaves are used in dyeing
black.

201. EXOGONIUM PURGA.--This plant furnishes the true jalap-tubers of
commerce. They owe their well-known purgative properties to their
resinous ingredients. Various species of Ipom[oe]a furnish a
spurious kind of this drug, which is often put in the market as
the genuine article.

202. EXOSTEMMA CARIBAEUM.--This West Indian plant has become naturalized
in southern Florida. It belongs to the cinchona family and is
known as Jamaica bark. It is also known as Quinquina Caraibe. The
bark is reputed to be a good febrifuge, and also to be employed as
an emetic. It is supposed to contain some peculiar principle, as
the fracture displays an abundance of small crystals. The
capsules, before they are ripe, are very bitter, and their juice
causes a burning itching on the lips.

203. FERONIA ELEPHANTUM.--The wood apple or elephant apple tree of
India, belonging to the family _Aurantiaceae_. It forms a large
tree in Ceylon, and yields a hard, heavy wood, of great strength.
It yields a gum, which is mixed with other gums and sold under the
name of East Indian gum arabic. The fruit is about the size of an
orange, and contains a pulpy flesh, which is edible, and a jelly
is made from it, which is used in cases of dysentery. The leaves
have an odor like that of anise, and the native India doctors
employ them as a stomachic and carminative.

204. FEVILLEA CORDIFOLIA.--The sequa or cacoon antidote of Jamaica. It
belongs to the cucumber family, and climbs to a great height up
the trunks of trees. The seeds are employed as a remedy in a

effects of poison; they also contain a quantity of semisolid fatty
