In other words, unites with the oxygen

the oxide Of tin gradually takes leave
Of the iron by evaporating into the air,

work for them These forces unite the
atoms Of the metals with those of the
oxygen. Then the molecules of these
oxides are carried away by the atmos-
pheric electricity and disposed OF ac-
cording to circumstances.
If a small bottle or other piece OF
glass be placed on damp gronnd and
an old wornout tin bucket is turned
over it, the particles Of iron oxide will
be taken away by electric currents
from the old bucket and will be de-
posted partly on the glass, the re-
