Adieu. The more I see of the Musée, the more am I delighted. I often take advantage of the hospitable privilege accorded to foreigners, and come here on those days when the public are not admitted. I have then the united advantages of looking on uninterrupted by the noise of crowds, and of seeing the number of artists, of both sexes, (some professional, and some amateurs), who are busily employed in copying the most esteemed productions. I think it certain, that so favourable an opportunity will soon revive, in all its ancient splendour, the art of painting, which, for some years back, has been, undoubtedly, on the decline. I am, &c.

Paris, march the 26th, 1802 (5 germinal). MY DEAR SIR, We have had for some days delightful weather; and the parisians have taken advantage of it in the best manner, by passing several hours in the “_bois de Boulogne_,” which answers in some respects to our Hyde-park. From three till six o’clock, the champs Elisées, through which the road runs, leading to this favourite spot, and all the adjoining streets have been crowded every day during this week, with carriages of all descriptions. Berlins, chariots, curricles, gigs, cabriolets, sociables, &c. These united to innumerable horsemen and pedestrians, make the whole city assume a lively appearance.
