e at night, followed by physic in the morning.

COMMON SALT (_Chloride of Sodium_). Common table salt is an
anthelmintic, and may be used in an emergency. Salt water is a very
common domestic remedy for worms. _Dose_--In solution, one-quarter to
one-half teaspoonful.

BALMONY (_Chelone Glabra_). This is also tonic and anthelmintic, and is
valuable in debility, dyspepsia, jaundice, and hepatic affections. It
also is known as Snake-head. _Dose_--Of the infusion, one to two ounces;
of the concentrated principle, Chelonin, from half to one grain.

MALE FERN (_Aspidium Filix Mas_). Male Fern is the anthelmintic which is
considered especially effectual in removing the tape-worm. _Dose_--Of
the powder, one to two drachms, given morning and evening in syrup,
followed by a brisk cathartic. The dose of the tincture of the buds in
ether is from eight to thirty drops.

POPLAR (_Populus Tremuloides_). The White or Aspen Poplar is a common
tree, and contains active principles termed Populin and Salicin, both of
which are tonic. An infusion of the bark is a remedy for worms.
_Dose_--Of the tea made from the bark, one to four ounces; of Populin,
from one-half to two grains.

ANTIPERIODICS.

It is well understood that malarial diseases are characterized by a
periodicity which indicates their nature. Antiperiodics prevent the
recurrence of the periodic manifestations, and hence their name.

QUININE (_Sulphate of Quinia_). Quinine is a tonic, febrifuge, and
antiperiodic. It should generally be administered during the intervals
between the febrile paroxysms. It is beneficial also in all diseases
accompanied by debility. The dose varies from one to six grains
according to indications. Frequently it is given in much larger
quantities, but we cannot advise such for domestic use.

PRUSSIAN BLUE (_Ferri Ferrocyanidum_). Ferrocyanide of Iron is an
excellent tonic and antiperiodic remedy, and often is combined with
quinine. _Dose_--From two to five grains.

diaphoretic, aperient, and possesses some antiperiodic properties; the
warm infusion is emetic. _Dose_--Of the infusion, one to four ounces; of
the fluid extract, from half to one teaspoonful; of the active
principle, Eupatorin, one to three grains.
