injections of the tincture TTlxv—xxx are valuable in sudden heart
depression resulting from any cause, such as shock or collapse
from hemorrhage, or surgical operations, etc., etc. Digitalis must
be used with care in fatty heart, aneurism, and cerebral endo-
carditis.
ELECTROZONE.
Derivation.—Electrozone consists of a fluid which is nothing
but sea or salt water subjected to an electrolytic current. It is
a clear liquid, neutral in reaction, with the odor of free chlorine,
and a disagreeable, salty taste. It was discovered by A. E.
Woolf, who has succeeded in sterilizing polluted water with it
on a large scale.
Properties and Dental Uses.—Dr. C. F. W. Bodecker recom-
mends electrozone as an efficient antiseptic, and claims that it
has given him uniformly satisfactory results in the treatment of
purulent pulpitis. His method is to open the pulp-chamber
freely, and then syringe with tepid water. The electrozone is
then introduced into the pulp-chamber on a small piece of cotton
saturated with it, followed by one or two smaller pledgets mois-
tened with the electrozone. The patient is then directed to
renew only the last piece of cotton, from three to five times
daily, or at least after every meal, using the precaution to rinse
the mouth with a weak solution of electrozone (about a teaspoon-
ful in a tumbler of water) previous to the removal of the cotton.
Every pledget of cotton, previous to its introduction, should
be moistened with pure electrozone, and packed as tight in the
cavity of the tooth as possible. When the tooth has been treated
in this manner for two or three days, the pulp-canal may be
cleaned out and filled at once, without any fear of future perice-
mentitis, provided that an infection of pericementitis has not
already occurred.
ENZYMOL.
Derivation.—Enzymol is a purified solution of the proteolytic
enzyme for external application, and is obtained by a direct solu-
tion from the stomach glands in a sterilized menstruum, being
