In the year 1709, the inhabitants of Rome (without including eight or ten thousand Jews), amounted to 138,568 souls (Labat, Voyages en Espagne et en Italie , tom. iii. p. 217, 218). In 1740, they had increased to 146,080; and in 1765, I left them, without the Jews, 161,899. I am ignorant whether they have since continued in a progressive state.
