198 NOTES ON THE NEWER REMEDIES.
TETRA-ETHYL-AMMONIUM.
This substance, supposed to be a normal constituent
of the animal body, is obtained by decomposing its iodide
by moist nitrate of silver, or its sulphate by means of
baryta. It has the chemical composition NEt4OH.
Physical Properties.- Tetra-ethyl-amnmonium occurs
in deliquescent hair-like needles. It is a very bitter sub-
stance, strongly alkaline, and absorbs carbon dioxide from
the air. This drug forms numerous salts with the various
acids, and beautiful double-salts with metals such as gold,
mercury, platinum, etc.
Physiological Action.-Locally applied to the skin,
it is said to act as a caustic, and in concentrated form to
burn the tongue. It has the power of saponifying fats.
It is said to exercise no deleterious influence on the cir-
culation, the respiration, or the bodily temperature.
Therapeutic Applications. This recently-introduced
remedy has been found of unusual value as a solvent for
urea and uric acid, being considered superior to piper-
azine. It has given very satisfactory results in the treat-
ment of acute rheumatism, and appears to be indicated
in gouty and other rheumatic conditions.
Administration. -Tetra- ethyl- ammonium may be
given in daily doses of from Io to 20 minims (o.6o to
1.20 gramme) of a Io per cent. solution. Hypodermat-
ically, it may be administered in amounts of not more
than io minims (o.6o gramme) of I per cent. solution.
The latter solution can also be employed by cataphoresis,
especially in cases of gouty joints or rheumatic tophi.
Toxicology.-Unlike tetra-methyl-amioniumz, which
is a poisonous substance, tetra-ethyl-ammonium appears
to be a safe remedy and destitute of noxious properties.
TETRONAL.
This term is applied to diet/zyl-slp/zon-diethzylmethane,
which is represented by the formula (CH5)2,C,(SOC2H,)2.
Physical Properties.-Tetronal appears in the form
of brilliant scales which melt at 185 F. (850 C.) and
