A history of nitrous oxide and oxygen anaesthesia IVE: Henry Hill Hickman in his time.

More evidence is presented: a questionable letter from a grateful patient; Hickman's stewardship at a Charity Ball; the baptism of his children at Shifnal. The identities of "John" and "Glover", mentioned in Hickman's letter from Paris, and the marriage of one of Hickman's cousins to the son of a French emigré, are discussed. A recorded gift places Eliza in Paris with Henry on November 10, 1828. The need to assess the evidence in the context of its time and place is stressed.
