Tits May 1960 issue contains a technique by Peter Weaner or counting the nmnber of ones in a word. The text seems to reply that techniques other than the ones mentioned are not mown. The following description of a technique for achieving he same results has been known by the writer and several of his ~ssociates for some time; it may be beneficial to the membership ,o publish it, although I have no knowledge of its origin or pre~ious publications.
