Note 030
See in the Memoires de l'Academie tom. xxxv. p. 747-758,
a dissertation of M. d'Anville on the extent of
Constantinople. He takes the plan inserted in the Imperium
Orientale of Banduri as the most complete; but by a series
of very nice observations he reduces the extravagant
proportion of the scale, and, instead of 9500, determines
the circumference of the city as consisting of about 7800
French toises.
