4. Ingenhousz traveled a more circuitous route than he had anticipated, only arriving in Paris on Dec. 29. He detailed his itinerary in a paper on air quality written to the Royal Society on Jan. 22, 1780, published in Philosophical Transactions, vol. LXX (1780), part one, pp. 354–77. The date of his arrival in Paris is specified in the revised version of that paper: Ingenhousz, Nouvelles expériences et observations sur divers objets de physique, I (Paris, 1785), p. 320.
