Bas Empire, tom. xx. p. 417) allows Constantinople a million of inhabitants, of whom 60,000 horse, and an infinite number of foot-soldiers. In its present decay, the capital of the Ottoman empire may contain 400,000 souls (Bell's Travels, vol. ii. p. 401, 402); but as the Turks keep no registers, and as circumstances are fallacious, it is impossible to ascertain (Niebuhr, Voyage en Arabie, tom. i. p. 18, 19) the real populousness of their cities.
