1~ Tix have usually only poor convergence propernonlinear case the averages~ i= o ties, namely weak convergence. In addition to these aforementioned averages, there are several others, which are identical to the usual Cesaro averages, if T is linear. In this note we study an iteration scheme, first considered by Halpern [2]. There a sequence~=(~ n) in [0, i] is given and A~ x is defined inductively by
