The _thèâtre des arts_ or grand French opera, the _opera buffa_ or Italian comic opera, the _théâtre Feydeau_ or French comic opera, and the _théâtre Français_, chiefly engage my attention. Yesterday evening I went to the last-mentioned theatre purposely to see Mademoiselle CONTAT, who played in both pieces. The first was _Les Femmes Savantes_, a comedy, in which Molière, wishing to aim a blow at female pedantry, has, perhaps, checked, in some French women, a desire for improvement; the second was _La fausse Agnès_, a laughable afterpiece. Notwithstanding the enormous _embonpoint_ which this celebrated comic actress has acquired since I saw her last on the Parisian stage upwards of ten years ago, she acquitted herself with her accustomed excellence. I happened to sit next to a very warm admirer of her superior talents, who told me that, bulky as she was become, he had been highly gratified in seeing her perform at _Rouen_ not long since, in her favourite character of _Roxalane_, in _Les Trois Sultanes_. "She was much applauded, no doubt." observed I. --"Not at all," replied he, "for the crowd was so great, that in no part of the house was it possible for a man to use his hands." LETTER X. _Paris, November 2, 1801._ On reaching Paris, every person, whether Jew or Gentile, foreigner or not, coming from any department of the republic, except that of _La Seine_, in which the capital is situated, is now bound to make his appearance at the _Préfecture de Police_. The new-comer, accompanied by two housekeepers, first repairs to the Police-office of the _arrondissement_, or district, in which he has taken up his residence, where he delivers his travelling passport; in lieu of which he receives a sort of certificate, and then he shews himself at the _Préfecture de Police_, or General Police-office, at present established in the _Cité_. Here, his name and quality, together with a minute description of his person and his place of abode, are inserted in a register kept for that purpose, to which he puts his signature; and a printed paper, commonly called a _permis de séjour_, is given to him, containing a duplicate of all these matters, filled up in the blanks, which he also signs himself. It is intended that he should always carry this paper about him, in order that he may produce it when called on, or, in case of necessity, for verifying his person, on any particular occasion, such as passing by a guard-house on foot after eleven o'clock at night, or being unexpectedly involved in any affray. In a word, it answers to a stranger the same end as a _carte de sureté_, or ticket of safety, does to an inhabitant of Paris.
