This painting satirically illustrates animal magnetism or magnetic therapy. On the wall are three pictures: Loutherbourg, an artist turned quack, Yeldell (with donkey ears) a follower of Mesmer, and probably de Mainaudiac, a doctor who advertised magnetic cures and animal magnetism. Also in the painting are packets of "Mag Snuff" and an open book that reads, "Magnetic Effluvia" and "List of Cures" with a dog urinating on it., Labels on the back read “1831 From James S. Earle & Sons, Earle’s Galleries, No. 816 Chestnut Street Philadelphia” and “Library Company of Philadelphia. 3775.”, Engraving in The Attic Miscellany. London: Bentley, 1791 (Vol. I, pictured on p. 121). Engraving is signed: Drawn by Collings, etched by Barlow, published by Bentley & Co., 1790.
