MERCURIC GALLA TE.

Administration.-This remedy is best given in pill
form or emulsion, in single doses of from f2 to 2 grains
(0.03 to 0.12 gramme).
MERCURIAL IMIDO-SUCCINATE.
The formula of this compound is given as (C2H4-
(CO)2N) Hg.
Physical Properties.-This substance appears in the
form of a white crystalline powder.
Solubility.-The i;nido-succinatc of mercury is soluble
in water and in alcohol, in the proportion of I to 25 and
I to 300 parts respectively.
Therapeutic Applications.-Jlrcuric imido-sluccinzate
has been used chiefly as an antisyphilitic.
Administration.-The dose of this remedy is 5 grain
(o.o0I2 gramme).
MERCURIC GALLATE.
This combination is said to have a close chemical re-
lation to the tannate and to be more stable than the
latter. Ga//atc of mcrcry contains about 37.17 per cent.
of the metal.
Physiological Action. Owing to a rapid absorp-
tion, the presence of mercury has been detected in the
urine within twenty-four hours after the ingestion of the
gallate. This drug has caused apparently no mercurial
poisoning of any kind, nor even stomatitis or salivation.
Therapeutic Applications.- Mercuric gallate has been
used with good results as a powerful antisyphilitic rem-
edy, ranking in utility with the protiodide and the bi-
chloride, with the advantage, as just intimated, of not
causing ptyalism  when administered in therapeutic
doses. This combination has been employed especially
in the second and tertiary forms of syphilis. It is said
to have rendered marked service in the grave forms of
the second stage of the disease as observed in alcoholic
or cachectic patients. In cases in which general cachexia,
bad teeth, or digestive disturbances are prominent factors
