I'm attempting to make some comparative graphics of various units of measure re. type-making history...
I'm trying to suss this out with http://en.wikipedia.org/wiki/Foot_(unit)
Specifically regarding '¶ 2 Of Letter' of Moxon's ...Art of printing:
When he speaks of 'feet' in 1683, should this be regarded as The Roman foot divided by the 10/11 rule of the 'Composition of Yards' law?
∴ 10.59090... modern inches?
Alternately, preferably - does such a chart already exist?
