  The stability of the bright solitary wave solution to the perturbed
cubic-quintic Schroedinger equation is considered. It is shown that in a
certain region of parameter space these solutions are unstable, with the
instability being manifested as a small positive eigenvalue. Furthermore, it is
shown that in the complimentary region of parameter space there are no small
unstable eigenvalues. The proof involves a novel calculation of the Evans
function, which is of interest in its own right. As a consequence of the
eigenvalue calculation, it is additionally shown that N-bump bright solitary
waves bifurcate from the primary wave.
