He said *density*, as I have already explained.  He did not have
distinct words for weight and density (and perhaps he did not know the
need to be as careful as we are about the difference).  Denser objects
of identical mass and shape do fall faster through a medium, and the
context makes it clear that this.

If you don't like it, get a glass of water and check.
