f water), one to two ounces.

Sage (_Salvia Officinalis_). The warm infusion drunk freely is a
valuable, domestic diaphoretic.

VIRGINIA SNAKE-ROOT (_Aristolochia Serpentaria_), is an efficient
agent. _Dose_--Of infusion, one to two ounces; of tincture, one-fourth
to one teaspoonful; of fluid extract, one-fourth to one-half
teaspoonful.

JABORANDI (_Pilocarpus Pinnatus_). Jaborandi increases the flow of
saliva, causes profuse perspiration, and lowers the temperature of the
body. In doses of from twenty to sixty drops of the fluid extract,
administered in a cup of warm water or herb-tea on going to bed, we have
found it very effectual for breaking up recent colds. We have also found
it valuable in whooping-cough, in doses of from three to ten drops,
according to the age of the child, given three or four times a day. The
fluid extract may be obtained at almost any drug-store.

May-flower. ]

MAY-WEED (_Maruta Cotula_), is also known as Wild Chamomile, and
Dog-fennel. It is not much used, though it is a powerful diaphoretic.
_Dose_--Of infusion, one to two ounces.

CATNIP (_Nepeta Cataria_). A deservedly popular, domestic remedy, always
acceptable, and certain in its action. The warm infusion is the best
form for its administration. It may be drunk freely.

GINGER (_Zingiber Officinale_). The hot infusion may be sweetened and
drunk as freely as the stomach will bear.

DR. PIERCE'S COMPOUND EXTRACT OF SMART-WEED. This is unsurpassed as a
diaphoretic agent, and is much more certain in its operation than any
simple diaphoretic.

DILUENTS.

Any fluid which thins the blood or holds medicine in solution is called
a diluent. Pure water is the principal agent of this class. It
constitutes about four-fifths of the weight of the blood, and is the
most abundant constituent of the bodily tissues. Water is necessary, not
only for digestion, nutrition, and all functional processes of life, but
it is indispensable as a menstruum for medicinal substances. It is a
necessary agent in depuration, or the process of purifying the animal
economy, for it dissolves and holds in solution deleterious matter,
which in this state may be expelled from the body. In fevers, water is
necessary to quench the thirst, promote absorption, and incite the skin
and kidneys to action. Its temperature may be varied according to
requirements. Diluents are the vehicles for
