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.
