_Dolichos
biflorus_(_?_). Oil is also expressed in India from the seed of the
_Argemone mexicana_, which is used for lamps and in medicine; and from
the seeds of the cashew nut (_Anacardium occidentale_), from _Sapindus
marginatus_, and the country walnut (_Aleurites triloba_.) The fruit
of the _Chirongia sapinda_, (or _Buchanania latifolia_,) yields oil.
From the seeds of the _Pongamia glabra_, or _Galidupa arborea_, a
honey brown and almost tasteless oil is procured, which is fluid at
common temperatures, but gelatinises at 55 degrees.

Other sources of oil are the _Celastrus paniculatus_ (_?_) _Balanites
Egyptictca_ and the saul tree (_Shorea Robusta_).

THE CANDLE-TREE or PALO BE VELAS, (_Parmentiera cereifera_,
Seemann.)--This tree, in the valley of the Chagres, South America,
forms entire forests. In entering them a person might almost fancy
himself transported into a chandler's shop. From all the stems and
lower branches hang long cylindrical fruits, of a yellow wax color, so
much resembling a candle as to have given rise to the popular
appellation. The fruit is generally from two to three, but not
unfrequently four feet long, and an inch in diameter. The tree itself
is about 24 feet high, with, opposite trifoliated leaves, and large
white blossoms, which appear throughout the year, but are in greatest
abundance during the rainy season. The _Palo de Velas_ belongs to the
natural order _Crescentiaceae_, and is a _Parmentiera_, of which genus
hitherto only one species, the _P. edulis_, of De Candolle, was known
to exist. The fruit of the latter, called _Quauhscilote_, is eaten by
the Mexicans, while that of the former serves for food to numerous
herds of cattle. Bullocks especially, if fed with the fruit of this
tree, guinea-grass, and _Batatilla_ (_Ipomoea brachypoda_, Benth.),
soon get fat. It is generally admitted, however, that the meat
partakes in some degree of the peculiar apple-like smell of the fruit,
but this is by no means disagreeable, and easily prevented, if, for a
few days previous to killing the animal, the food is changed. The tree
produces its principal harvest during the dry season, when all the
herbaceous vegetation is burned up, and on that account its
cultivation in tropical countries is especially to be recommended; a
few acres of it would effectually prevent that want of fodder which is
always most severely felt after the periodical rains have
ceased.--("Hooker's Journal of Botany.")
