  We present results from a first test of the Gaussianity of degree-scale
cosmic microwave background (CMB) anisotropy. We investigate Gaussianity of the
CMB anisotropy by studying the topology of CMB anisotropy maps from the QMAP
and Saskatoon experiments. We also study the QMASK map, a combination map of
the QMAP and Saskatoon data. We measure the genus from noise-suppressed
Wiener-filtered maps at an angular scale of about 1.5 degrees. To test the
Gaussianity of the observed anisotropy, we compare these results to those
derived from a collection of simulated maps for each experiment in a Gaussian
spatially-flat cosmological constant dominated cold dark matter model. The
genus-threshold level relations of the QMAP and Saskatoon maps are consistent
with Gaussianity. While the combination QMASK map has a mildly non-Gaussian
genus curve which is not a consequence of known foreground contamination, this
result is not statistically significant at the 2 sigma level. These results
extend previous upper limits on the non-Gaussianity of the large angular scale
(> 10 degrees) CMB anisotropy (measured by the COBE DMR experiment) down to
degree angular scales.
