Cholera mapping
Grainger created detailed density maps illustrating the cholera epidemic's impact. These maps highlighted the intensity of cases by political district and sub-district, offering a visual representation of the epidemic's spread.
Reporting
His findings were included in the General Board of Health report, "Report on the Epidemic Cholera of 1848 & 1849." This report, published in 1851, detailed the epidemic's progression and the board's investigative efforts. Dr. Grainger's observations and maps were integral to understanding the cholera outbreak.
