About 100 steel guns. of the siX-inch

constructed on the same general principle,
are now IN course OF completion FOR the
larger iron-clads.

4 new electric battery has been made by
TomassI and Radiguet. Both % the elec-

and the other covered on its horizontal
upper surface with fragme' Is Of pla,inized
coke. The two are separated by means Of

Plain this anomaly by the consideration
that the absorption Of heat results no,

c. Schmitt and \. Cobicnzi, the dmcri-
can Chemical journal says, have made 4
careful investigation Of the unfcrmcntlble
substances found in commercial starch,
sugars, and bave succeeded in isolating
8 definite compound, to which they give
the name of "galli>in." PbysiOlog cal cX-
perimeDts on the lower animals and on
human beings demonstrated clearly that
galIiSin has, neither directly nor indirectly,
any bad effect on health.
