and sometimes a red eruption. It is eliminated chiefly by the
urine.
Opium is the antidote, or hypodermic injections of morphine.
When applied to the eyebrows, belladonna causes dilatation of the
pupils.
Therapeutic Uses.—Belladonna is extensively employed, either
alone or in combination with sulphate of quinia, in the treatment
of neuralgia ; also in mania, Bright's disease, epilepsy, lead colic,
spasmodic affections, diseases of the cerebro-spinal system, as a
preventive of scarlatina, night sweats of phthisis, etc.
Dose.—Of powdered belladonna, gr. ss to gr. j, daily ; of the
extract, gr. y^ to gr. j ; of the tincture, gtt. v to gtt. xx. Bella-
donna should not be given immediately before or after meals, as
it decreases the gastric fluids. (See Atropine.)
BENZOIC SULPHIDE OF SODIUM.
Benzoic Sulphide of Sodium is obtained by dissolving a large
quantity of benzoic acid in a concentrated solution of sulphide of
sodium. It is a valuable antiseptic for dressing wounds, and may
be used as a wash, lotion or injection, its antiseptic properties be-
ing very active and healing. Thirty to forty-five grains are used
to the quart of water. Heckel considers it to be equal to car-
bolic acid, and superior both to sublimate and iodoform, as it is
not poisonous like corrosive sublimate, and is free from the dis-
agreeable eflFects of iodoform. It is very soluble in water and
contains the antiseptic properties of its two principal ingredients
benzoic acid and sulphite of sodium. It is harmless, even when
given in large doses.
BISI^UTH SUBNITRAS—SUBNITRATE OF BISMUTH.
Formula.—B\0^0^+ HgO.
Derivation—The metal Bismuth Bismuthum^ Formula Bi,
from which the subnitrate is obtained, is found native in Europe
and America, and generally in combination with sulphur and ox-
ygen. It fuses at 510° F., and is brittle and pulverizable. It is
employed in the dental laboratory for making fusible metal alloys
for dies and counter-dies.
