  We have analyzed the far UV-spectrum of the globular cluster M79. We show
that the nearly Gaussian mass distribution of zero-age horizontal-branch stars,
as derived by Dixon et al.(1996), is able to reproduce the far-UV Hopkins
Utraviolet Telescope (HUT) spectrum, if there is a luminous UV-bright star of
about an effective temperature of 9,500 K within the HUT entrance slit, or,
more likely, if the horizontal branch morphology becomes considerably redder in
the core of M79, as observed in some other centrally condensed globular
clusters. Agreement between the synthetic and observed far-UV spectra for M79
would also be improved if the surface abundances of the heavy elements in the
hot horizontal-branch stars were enhanced by radiative diffusion. Contrary to
Dixon et al. (1996) we do not need extremely low gravities to reproduce the
width of Ly alpha.
