Rufus P. Williams, writing in 1131 in the journal School Science and Mathematics, hypothethesizes a "pure" dozenal system of weights and measures, with a foot for length; a bushel for weight; and a pint for volume, and the superiority of this system over decimal alternatives. While he's very pessimistic about the potential success of dozenals at all, he does make some excellent observations about twelve as the ideal basis for a system of measures.
