He was an intimate friend of
John Horne Tooke, to whose house at
Wimbledon Bosville used to drive down in a
coach and four to dinner every Sunday during the spring and autumn for many years, and is mentioned in his
Diversions of Purley. Possessed of a large fortune he was exceedingly generous with his money, and was unbounded in his hospitality. Every weekday he used to receive some of his friends at dinner at his house in Welbeck Street. The party never exceeded twelve in number, and the dinner hour was always five o’clock punctually. A slate was kept in the hall, in which any of his intimate friends might write his name as a guest for the day, Besides Horne Tooke,
Sir Francis Burdett, 5th Baronet, Lords Hutchinson and Oxford, Parson Este, and others, often availed themselves of this privilege. The first stroke of five was the signal for going downstairs, and the host made a point of never waiting for any of his guests. In accordance with his favourite maxim, namely
Some say better late than never; I say better never than late, an old friend who arrived one day four minutes late was refused admittance by the servant, who said that his master was "busy dining". Though his health declined and his convivial powers failed, he still continued his dinner parties to the last. Even when compelled to remain in his bedroom, the slate was hung in the hall as usual, and on the very morning of his death he gave his orders for the dinner at the usual hour. ==Death and burial==
