Webster's 1828 Dictionary
AMMONIUM
n.A name given to the supposed metallic basis of ammonia. If mercury, at the negative pole of a galvanic battery, is placed in contact with a solution of ammonia, and the circuit is completed, an amalgam is formed, which, at the temperature of 7 degrees or 8 degrees of Fahrenheit, is of the consistence of butter, but at the freezing point is a firm and crystallized mass. This amalgam is supposed to be formed by the metallic basis, ammonium.
