shown on a second graduated scale, E. Having obtained the metacentric
height, reference to a diagram will at once show the whole range of
stability; and this being ascertained at each loading, the stowage of
the cargo can be so adjusted as to avoid excessive stiffness in the one
hand and dangerous tenderness on the other. It will thus be seen that
Mr. Taylor's invention promises to be of great practical value both in
the hands of the ship-builder and ship-owner, who have now an instrument
placed before them, by the proper use of which all danger from
unskillful loading can be entirely avoided.--_The Engineer_.

SCRIVANOW'S CHLORIDE OF SILVER PILE.


Considerable attention has been attracted lately at Paris among those
who are interested in electrical novelties to a chloride of silver
pile invented by Mr. Scrivanow. The experiments to which it has been
submitted are, in some respects, sufficiently extraordinary to cause us
to make them known to our readers, along with the inventor's description
of the apparatus.

Mr. Scrivanow's intention appears to be to apply this pile to the
lighting of apartments, and even to the running of small motors, and,
for the purpose of actuating sewing machines, he has already constructed
