On the Mode of Communication of Cholera is the book in which the London physician John Snow argued that cholera is spread by contaminated water rather than by bad air. A short first edition appeared in 1849, after the epidemic of 1848–1849; the second edition of 1855, much enlarged, added the evidence from the epidemic of 1854 that made the work famous.
