In the library, that opens on a terrace, which is to be covered with a _berceau_, and converted into a garden, are two mirrors, _vis-à-vis_ to the two glass doors that communicate from the _salon_; so that on entering this last, the effect produced is exceedingly pretty. Another large mirror is placed at the end of the library, and reflects the terrace. When my books and various treasures are arranged in this suite I shall be very comfortably lodged. My _chambre à coucher_, dressing-room, and boudoir, are spacious, and beautifully decorated. All this sounds well and looks well, too, yet we shall leave the Rue de Bourbon with regret, and Lord B---- now laments that we did not secure it for a long term. Drove in the Bois de Boulogne. A lovely day, which produced a very exhilarating effect on my spirits. I know not whether others experience the same pleasurable sensations that I do on a fine day in spring, when all nature is bursting into life, and the air and earth look joyous. My feelings become more buoyant, my step more elastic, and all that I love seem dearer than before. I remember that even in childhood I was peculiarly sensible to atmospheric influence, and I find that as I grow old this susceptibility does not diminish. We dined at the Rocher de Cancale yesterday; and Counts Septeuil and Valeski composed our party. The Rocher de Cancale is the Greenwich of Paris; the oysters and various other kinds of fish served up _con gusto_, attracting people to it, as the white bait draw visitors to Greenwich. Our dinner was excellent, and our party very agreeable. A _dîner de restaurant_ is pleasant from its novelty. The guests seem less ceremonious and more gay; the absence of the elegance that marks the dinner-table appointments in a _maison bien montée_, gives a homeliness and heartiness to the repast; and even the attendance of two or three ill-dressed _garçons_ hurrying about, instead of half-a-dozen sedate servants in rich liveries, marshalled by a solemn-looking _maître-d'hôtel_ and groom of the chambers, gives a zest to the dinner often wanted in more luxurious feasts. The Bois de Boulogne yesterday presented one of the gayest sights imaginable as we drove through it, for, being Sunday, all the _bourgeoisie_ of Paris were promenading there, and in their holyday dresses. And very pretty and becoming were the said dresses, from those of the _femmes de négociants_, composed of rich and tasteful materials, down to those of the humble _grisettes_, who, with jaunty air and roguish eyes, walked briskly along, casting glances at every smart toilette they encountered, more intent on examining the dresses than the wearers.
