Career
Du Plessis" bizarre 320-page manuscript is illustrated with hand-coloured drawings by the author himself. These include "John Grimes, a Dwarf", "Two Sisters conjoined", "A Woman Seven foot High", "A Woman with a Hog"s Face", "A Spotted Negro Prince" and "The Monstrous Tartar". The section headed "A Wild Girl found Near Chalons in Champagne" contains the earliest-known report in English of Marie-Angélique Memmie Le Blanc, the famous feral child of 18th-century France.
Shortly before his death, Du Plessis offered the manuscript and its illustrations to Sir Hans Sloane and they became part of Sloane"s foundation collection of the British Museum.
Du Plessis" fascination with human strangeness and prodigies of all kinds began in his youth when he dug up the body of a stillborn two-headed child, a cousin, in the garden of his family home at Pithiviers in north-central France.
