QUALITIES. _Form_, a violet coloured mass, which on exposure to air
becomes green, and is probably converted into a carbonate. _Taste_,
styptic and metalline. _Odour_, ammoniacal. CHEMICAL COMPOSITION. It is
a triple salt, a sub-sulphate of oxide of copper, and ammonia. The
Edinburgh College is certainly incorrect in calling it an _ammoniuret_.
SOLUBILITY, f℥j; of water dissolves ℈j of this salt. INCOMPATIBLE
SUBSTANCES; _Acids_; the _fixed Alkalies_; _Lime water_. MEDICINAL USES.
It is tonic and antispasmodic. Dr. Cullen first proposed its exhibition
in epilepsy, and it has frequently been employed with evident advantage
in that disease. It has been also given in chorea, after a course of
purgatives. Brera considers it quite equal to Arsenic, in the cure of
obstinate Intermittents; other physicians have commended it in cases of
Hysteria. FORMS OF EXHIBITION. It may be formed into pills with bread;
to which an addition of sugar has been recommended, to prevent them from
becoming hard; but we must remember that recent experiments have shewn
that sugar has the power of counteracting the operation of copper. Dose,
gr. 1/4 cautiously encreased to grs. v. twice a day. OFFICINAL
PREPARATIONS. _Liquor Cupri Ammoniati._ L.
