title: A history of nitrous oxide and oxygen anaesthesia. IVC: Henry Hill Hickman in his time.
abstract: Previous verdicts on Hickman set the scene. The genealogy of Hickman and his wife is explored, disclosing the identities of "Poor Mrs  Dudley of Shut End" and "Thomas Dudley of Kingswinford". Some previous evidence is explained by the bankruptcy of Hickman's father-in-law. The dubious means whereby Hickman qualified prematurely are examined.
