Print shows Fox firing a blunderbuss at a post which roughly suggests George III in back view: it is surmounted by a short wig and a hunting-cap decorated with the royal arms; round a protuberance simulating posteriors a circle is drawn with a bull's-eye at which Fox is firing. Fox wears a slouch hat with the inscription 'Ca-Ira' and behind him Priestley (left) and Sheridan (right) face each other with conspiratorial smiles. Sheridan is ramming the barrel of a pistol, saying, "Well! this new Game is delightful! - O Heavens! if I could but once Pop the Post!!! then you and me, - Dear Brother P, - Would sing with glee, - Full merrily Ca-ira! Ca-ira! Ca-ira!" Priestley holds out to him two books: "on the Glory of Revolution and on the Folly of Religion & Order", saying, "Here's plenty of Wadding for to ram down the Charge with, to give it force, & to make a loud Report.".
