  Recoil proton polarization observables were measured for both the p($\vec
{\rm e}$,e$^\prime\vec{\rm p}\,$) and d($\vec {\rm e}$,e$^\prime\vec{\rm
p}\,)$n reactions at two values of Q$^2$ using a newly commissioned proton
Focal Plane Polarimeter at the M.I.T.-Bates Linear Accelerator Center. The
hydrogen and deuterium spin-dependent observables $D_{\ell\ell}$ and
$D_{{\ell}t}$, the induced polarization $P_n$ and the form factor ratio
$G^p_E/G^p_M$ were measured under identical kinematics. The deuterium and
hydrogen results are in good agreement with each other and with the plane-wave
impulse approximation (PWIA).
