Manual of the Dozen System (MODS)
 |
|
||||||||||
This is a classic manual which was distributed to Members and interested corresponders, which contains descriptions of various basic dozenal concepts. Tables of logarithms, exponents, and fractions are included. Also includes part of Henry Churchman’s dozenal system of measure and a section offering dozenal references. This document definitely shows its age, but still provides a useful introduction to dozenal counting and mathematics. |
