3. The alcohols
obtained are wholesome, and can be put on the market without danger. 4.
Their superior quality gives these alcohols an extra value difficult
to calculate, but which is very notable. 5. The whole operation being
performed in closed vessels, there is absolutely no waste. 6. For the
same reason there is scarcely any danger of fire. 7. The management of
the works and the service are performed by the pressure of the gases
entirely; there are only a few cocks to be turned to perform all the
interior maneuvers, empty and fill the vessels, etc. Hence economy in
_personnel_.

ELECTROLYTIC DETERMINATIONS AND SEPARATIONS.
[Footnote: NOTE.--Each of these determinations was accompanied by a
series of results in which the practical determinations obtained from
the method described were compared with the theoretical contents of the
solutions of the various elements. These, however, would take up too
much room for insertion in these columns.]
By ALEX. CLASSEN and M.A. VON REIS; translated by M. BENJAMIN, Ph.B.,
F.C.S.
Ever since the electrolytic method for the estimation of copper came
into general use, numerous chemists have endeavored to adapt this
peculiarly simple and elegant method to the determination of other
metals.
