We present an alternate interpretation to the comments by P. Thalmeier (preceding paper, Phys. Rev. B 44, 7120 (1991)) based on the assumption that the antiferromagnetic transition is a secondary effect of some other phase transition at {ital T}{sub {ital N}} (C. M. Varma (unpublished); see also Palstra {ital et} {ital al}., Phys. Rev. Lett. 55, 2727 (1985)). This view is motivated by the observation that the ordered moment in URu{sub 2}Si{sub 2} is very small ({similar to}0.02{mu}{sub {ital B}}) and similar to the ordered moment in UPt{sub 3}, another heavy-fermion system, and yet the specific-heat anomaly is at least 2 orders of magnitude larger in URu{sub 2}Si{sub 2} than in UPt{sub 3}.
