  We calculate the energy and condensate fraction for a dense system of bosons
interacting through an attractive short range interaction with positive s-wave
scattering length $a$. At high densities, $n>>a^{-3}$, the energy per particle,
chemical potential, and square of the sound speed are independent of the
scattering length and proportional to $n^{2/3}$, as in Fermi systems.
