In the last few years there has been a renewed interest in the problem of true polar \udwander (TPW) induced by slowly varying mass redistribution. Moser et al.,(1992) disagrees \udwith our own results, Ricard et. al.(1992) on three different points:(1) The amplitude of the \udnon-diagonal inertia perturbations that should be considered;(2) The importance of a \udpossible relative angular momentum carried by the mantle; and (3) The rotational equations \udfor the Earth. In this comment, we want to briefly restate the basic equations and to discuss ..
