Thanks also for the elucidation on "doubly positive." I had suspected that was the connection, but because Bosanquet didn't use that terminology, I wasn't absolutely sure. Digging up a copy of XH 2, I see now that in Erv Wilson's classification of tonal systems, he goes up to "triply positive" systems; however, he lists no corresponding "doubly negative" (e.g. 50-tET) or "triply negative" (e.g. 33-tET) systems. As far as using systems other than 12-tET to determine positive- and negativeness, I need to study Wilson's article in XH 3 in much greater depth before I can venture a coherent comment.
