This is a solution of ammoniacal gas in spirit; in which a small portion
of the sub-carbonate is also generally present. It is not easy to
compare the strength of this preparation with that of the _Liquor
Ammoniæ_, or _Liquor Ammoniæ Sub-carbonatis_, so as to give their
medicinal equivalents, because the ammonia exists in a very different
state of combination. The first is a mere solution of ammoniacal gas in
water; in the second, as already stated, the ammonia exists as a
_sesqui-carbonate_, while in the one now under consideration the alkali
is in the state of a _carbonate_. This fact will explain the reason of
the present preparation being superior in pungency to the _Liquor
Ammoniæ Sub-carbonatis_. The Incompatibles are the same as those
enumerated under the head of _Ammoniæ Sub-carbonas_. It is a powerful
stimulant, but it is principally employed as the basis of the following
compounds; viz. _Spirit: Ammoniæ Aromat_. L.E.D. _Spirit: Ammoniæ
Succinatus_. L. _Tinctura Castorei Comp:_ E. _Tinct: Guaiaci comp:_ E.
_Tinct: Opii Ammoniat:_ E.
