  In a recent letter, R.G. Brown and M. Ciftan (Phys. Rev. Lett. 76, 1352,
1996) reported high precision Monte Carlo (MC) estimates of the static critical
exponents of the classical 3D Heisenberg model, which stand in sharp contrast
to values obtained by four independent approaches, namely by other recent high
statistics MC simulations, high-temperature series analyses, field theoretical
methods, and experimental studies. In reply to the above cited work we
submitted this paper as a comment to Phys. Rev. Lett.
