THE new church of _Sainte Genevieve_ was begun in 1757; but the building was discontinued during the last war; in 1784 it was resumed, and is at present almost finished. The whole length of the front is thus inscribed in very large gilt capitals: _Aux grands hommes: la Patrie reconnoissante_. To great men: their grateful country. And over the entrance: _Pantheon Francais. L'An III de la Liberte_. As to the size of Paris, I saw two very large plans of that city and of London, on the same scale, on which it was said, that Paris covered 5,280,000 square _Toises_, and London only 3,900,000. A _Toise_ is two yards; and from the plan it appeared to be near the truth. The new buildings which surround the garden of the Palais Royal form a parallelogram, that for beauty is not to be matched in Europe. They consist of shops, coffee-houses, music rooms, four of which are in cellars, taverns, gaming-houses, &c. and the whole square is almost always full of people. The square is 234 yards in length, and 100 in breadth; the portico which surround it consists of 180 arches. The celebrated _Jacobins_ are a club, consisting at present of about 1300 members, and so called, because the place of meeting is in the hall which was formerly the library of the convent of that name, in the _Rue St. Honore_, about 300 yards distant from the National Assembly. The proper name of the club is, _Society of the Friends of the Constitution_. There are three or four other societies of less note. The _Quai_, which was formerly called _des Theatins_ is at present named _Quai Voltaire_, in honor of that philosopher, who died there in the house of the Marquis de _Villette_, in 1778. The street which was formerly called _Platriere_, and in which the general post-office is situated, is called _Rue Jean Jaques Rousseau_, in honour of this writer, who resided some time in this street. I found him here in 1776, and he copied some music for me; he had no other books at that time than an English _Robinson Crusoe_ and an Italian _Tasso's Jerusalem_. He died 1st July, 1778, very soon after Voltaire, at the country seat of le Marquis _de Girardin_ about ten leagues from Paris; and is buried there, in a small island. And the street which was formerly called _Chaussee d'Antin_ is now named _Rue de Mirabeau_, in honour of the late patriot of that name. The church _des Innocens_ was pulled down in 1786, and the vast _cimetiere_ (burying ground) was filled up. Every night, during several months, carts were employed in carrying the bones found there, to other grounds out of Paris; it is now a market for vegetables. Very near this place was a fountain, which is mentioned in letters patent so long ago as 1273. It was rebuilt with extraordinary magnificence in 1550, repaired in 1708, and at last, in 1788, carefully removed to the center of the market, where it now stands.
