=Dew=, _n._ The moisture of the air when condensed on any cold
surface. Dew does not _fall_; it is formed wherever moisture in the
air comes in contact with a substance colder than the air. Hence
there may be dew on the under as well as the upper side of a leaf.
=Dissolve=, _v._ L. _dis_, apart, _solvere_, loose; to separate the
solid particles of a body in a liquid; to melt. Sugar dissolves in
water.
=Double flowers=, _n._ All those whose petals are numerous. Sometimes
the stamens are changed into petals, as in double roses, and
sometimes even the pistils have become petals.
