In a recent correspondence<sup>1</sup>Lee and Edgar present a logarithmic number system and describe algorithms for the four basic arithmetic operations. Although it is encouraging to see continued interest in the area of specialized number systems, Lee and Edgar's work represents a duplication of work published in this TRANSACTIONS in 1975.
