John Snow, 'On the Mode of the Communication of Cholera', 1849. LSHTM Library & Archives.
The first edition of Snow's report was this slender pamphlet, here bound within a larger volume of other writings about cholera published in Europe between 1848 and 1875. With a growing public health crisis caused by the 1848 cholera outbreak, then in its second year, Snow hastily published this at his own expense. The essay focuses on outbreaks south of the River Thames and contains only one table.
