The map, with a dot marking the location of each case of cholera in Boston during the outbreak of 1849, is among the earliest of such maps, predating by five years Jon Snow's similar mapping of the Cholera outbreak in London. A landmark in medical topography. The report hints at the unsanitary conditions with sewage and water distribution that led to the outbreak but falls short of identifying the source. Front wrapper dated 1850, title page dated 1849. OCLC locates only 7 copies. Scarce. Sabin 6634.
