Abstract
We show that the reduced Gassner representation restricted to a normal free subgroup U n of the pure braid group, P n , is essentially the Magnus representation of U n / U '' n provided that the indeterminate y, used in defining this representation, is set to be one. Then, as a corollary, Lipschutz's result follows easily that is, in general, the kernel of the reduced Gassner representation restricted to U n is a subgroup of U '' n .
