  We explore the possibilities for measuring the quark content of the proton
and neutron using neutrino beams produced at a muon storage ring. Because of
the nature of the beams, small nuclear targets such as hydrogen and deuterium
can be considered, as well as polarized targets. The statistics expected from
these targets are calculated using nominal muon storage ring intensities, and
the resulting statistical errors on the numerous structure functions available
are given, for both polarized and unpolarized targets. It is shown that with a
relatively small target, the structure functions F_2, xF_3, xg_1 and xg_5 for
neutrinos and antineutrinos on protons and deuterium, either unpolarized or
polarized, could be determined with excellent precision over most of the
accessible kinematic range.
