Tanner, a prolific cartographer, wished to provide a geographic account of the spread of the worldwide cholera epidemic of 1817.  Statistics concerning the epidemic, he complained, were "given in such a loose and unconnected manner as to render a reference to them at once irksome and unprofitable." His publication included global, national and local maps, data tables showing number of deaths in different localities by country, and detailed maps of the United States and New York City with small red dots indicating points where the disease had broken out. Digital facsimile from the U.S. National Library of Medicine at this link unfortunately does not include the maps.
