Abstract
From apparent velocities of first arrivals across the Tonto Forest array for epicentral distances from 11° to 29° Niazi and Anderson derived a structure of the upper mantle deviating markedly from other structures as determined of late. It is found that on a different interpretation their data are in good accord with the Lehmann structure of the upper mantle.
