  Reduced large N gauge theories have a phase with unbroken center symmetry and
phases in which that symmetry is broken for Polyakov loops in one or more
lattice directions. The phase with unbroken symmetry is associated with the
zero temperature, infinite volume, infinite N theory while the phase in which
the symmetry is broken in just one lattice direction has been conjectured to be
the spatial reduction of the high temperature, infinite volume, infinite N
theory. Measurements of the scaling properties of the latent heat of the
transition between these phases test that hypothesis. The results indicate a
non-zero latent heat in the continuum limit. Substantial finite spacing effects
remain, and finer lattices will be needed to confirm physical scaling.
