Scale line

The map has a scale line of 4 miles, chequered in quarter
miles:-
Mill. Angl. quoru~ 4 uni Germanico aequip.
The scale 4 miles = 37.1 mm gives a scale about 3 map miles to
1 inch; the map miles are not statute miles. Another estimate of
scale can be got by comparing the position of a number of towns
with their known positions, using modern ngr positions. This
gives a scale:-
1 to 220000
3.5 miles to 1 inch
and provides an estimate of the map mile used by Blaeu, an:-
old english mile = 1.26 statue miles
