Three-quarter-length portrait of the Duke of Sussex, seated on the President’s chair of the Royal Society, the red leather upholstery surmounted by the Society’s coat-of-arms. Sussex is turned slightly to the right as viewed. On a table to the left rests a portfolio of papers and the Society’s silver gilt mace. The table is covered by a blue cloth edged with a gold fringe. Sussex wears a black velvet suit with matching tasselled cap, knee breeches and grey silk stockings. On his left leg is the garter with the motto partly visible ('Honi soit qui mal y pense'). He wears the Order of the Garter star and blue ribbon with an additional red ribbon from the neck, from which hangs the oval medallion of Knight Grand Cross, Order of the Bath. Beneath these a white high-collared shirt and waistcoat, the latter colourfully embroidered.
