Our main result is that if mu is an s-admissible measure in R-n and nu is an element of A(p)(d mu), then the measure d nu = nu d mu is ps-admissible. A two-weighted version of this result is also proved. It is further shown that every strong A(infinity) -weight omega in R-n, n greater than or equal to 2, is n/(n - 1)-admissible, that its power omega (1-1/n) is 1-admissible and that the weights W1-p/n With 1 < p < n are q-admissible for some q < p. A counterexample showing that we cannot take q = 1 in general is also given. Finally, a new class of p-admissible weights is described.
