Abstract
We have carried out extensive statistical, bit level and visual tests of several random number generators used in the applications of physics. Two of the generators tested were recently included in a paper by Ferrenberg {\it et al.} (Phys. Rev. Lett. {\bf 68}, 3382 (1992)) who reported correlations in their Monte Carlo simulations. As a possible explanation of this, they suggest bit level correlations in the random numbers. However, our tests find no evidence of such correlations, which highlights the importance of more careful physical tests of random number generators.
