With plates of copper I roofed it, I hung in its gates folding
doors of cedar wood, silver, gold, copper, and iron which my hands had
acquired in the lands which I ruled, I gathered in great quantities, and
placed them in the midst thereof." O.

DEPOSITING NICKEL UPON ZINC.
By H.B. SLATER.

To those interested in the electro deposition of nickel upon zinc, the
formula given below for a solution and a brief explanation of its use
will be of service.
The first sample of this solution was made as an experiment to see what
substances could be added to a solution of the double sulphate of nickel
and ammonium without spoiling it.
In addition to several other combinations and mixtures of solutions from
which I succeeded in obtaining a good deposit, I found that the solution
here given would plate almost anything I put into it, and worked
especially well upon zinc. In its use no "scraping" or rescouring or any
of the many operations which I have seen recommended for zinc needs
be resorted to, as the metal "strikes" at once and is deposited in
a continuous adherent film of reguline metal, and can be laid on as
heavily as nickel is deposited generally.
