  We investigate the monopole and vortex content of a meron pair by calculating
the points at which the transformation to the Laplacian Center Gauge is
ill-defined and by studying the behavior of Wilson loops. These techniques
reveal complementary aspects of the vortex and monopole structure, including
the presence of closed monopole lines and closed vortex surfaces joining the
two merons, and evidence for intersecting vortex surfaces at each meron.
