Perceval, in back view, and in barrister's wig and gown, holds a magic lantern by which he displays the Pope in the guise of a ragged beggar, for the benefit of John Bull and the King. George III is seated on the throne and looks at the screen through a telescope held by Eldon, inscribed 'Ill-done's Patent Magnifying Papascope'. The King, much alarmed at what he sees, clutches the mace which Eldon holds, with the Purse of the Great Seal attached to it. Beside the King (right) stand a bishop in back view, and a man wearing academic cap and gown. Perceval' s lantern is inscribed 'Percev[al] Humbu[g]'. Canning stands in front of it; Castlereagh beside it, both pointing at John Bull, a yokel in a smock, who has fallen to the ground in terror at the lantern-display, guineas falling from his pocket. The figure on the screen is an old man with patched robes, two keys hanging from a girdle, a sack of 'Bulls' on his back. In place of his triple crown he wears three hats like an old clothes' man, and for a crosier he has a branching stick. Close to the screen and with his back to it, Portland sits on a block of stone, talking to Hawkesbury. On the stone is drawn a wig on a block with the inscription 'Retrospective View of Portland' [i.e. as a former Whig]. In the shadow, between and behind Canning and Castlereagh, stands Melville in Highland dress; on his sporran: 'Ex Privy' [Counsellor]. Three other figures are not characterized. In the foreground a dog, its collar inscribed 'John Bull', is biting the 'Union Bill 1800', where it is headed by an Irish harp; a fragment, with the Royal Arms, has been torn off. The dog befouls a 'Catholic Petition'. On the wall is a large playbill: 'Theatre Royal St Stephens By his Majesty's Servants Feby 1807 Horrid Tragedy of Raw Head and Bloody Bones in a Red Cloak Mesrs Percivall, Canning, H-b-y [Harrowby], Portland Castlereagh Wonderful Deceptions, Messrs Proteus & Ill-done.' Below the design: 'What is this spectre of affright, / With which they would delude our sight? / A shadow thrown upon the wall / A magic-lanthorn-shew! thats all! Page 15.'
