<p>In this paper, we consider the recently proposed bosonic/heterotic duality that relates the heterotic superstrings to the noncritical bosonic string. Although the latter is nonsupersymmetric, it can be viewed as pseudo-supersymmetric in that the theory admits a consistent set of Killing spinor equations whose integrability conditions are satisfied by the equations of motion. We construct two classes of the dual pairs of BPS and pseudo-BPS solutions in the respective heterotic and bosonic strings and obtain their explicit Killing spinors. The existence of such dual pairs lends support to the proposed duality.</p>
