Preliminaries were signed in London on 1 October 1801. King George proclaimed the cessation of hostilities on 12 October. Upper-class British visitors flocked to Paris in the second half of 1802. William Herschel took the opportunity to confer with his colleagues at the Observatoire. In booths and temporary arcades in the courtyard of the Louvre, the third French "exposition des produits français" took place on 18–24 September. According to the memoirs of his private secretary, Fauvelet de Bourrienne, Bonaparte "was, above all, delighted with the admiration the exhibition excited among the numerous foreigners who resorted to Paris during the peace." Among the visitors was Charles James Fox, who received a personal tour from Minister Chaptal. Within the Louvre, in addition to the display of recent works in the Salon of 1802, visitors could see the display of Italian paintings and Roman sculptures collected from all over Italy under the stringent terms of the Treaty of Tolentino. J.M.W. Turner was able to fill a sketchbook from what he saw. Even the four Greek Horses of St Mark from Venice, which had been furtively removed in 1797, could now be viewed in an inner courtyard. William Hazlitt arrived at Paris on 16 October 1802. The Roman sculptures did not move him, but he spent most of three months studying and copying Italian masters in the Louvre. The English were not the only ones to profit by the halcyon lull in hostilities. From London, the Russian Simon Vorontsov noted to a correspondent, "I hear that our gentlemen are making extravagant purchases in Paris. That fool Demidov has ordered a porcelain dinner service every plate of which costs 16 gold louis." For those who could not get there, Helmina von Chézy collected her impressions in a series of vignettes contributed to the journal "Französische Miscellen", and F. W. Blagdon and John Carr were among those who brought up to date curious English readers, who had felt starved for unbiased accounts of "a people under the influence [ ] of a political change, hitherto unparalleled... During a separation of ten years, we have received very little account of this extraordinary people, which could be relied on," Carr noted in his Preface. A number of French émigrés returned to France, under the terms of relaxed restrictions upon them. French visitors also came to England.
