Three interesting examples of medical cartography in Washington, DC in 1887. The first map shows the locations of individual fatalities by city block for three lung diseases in Washington in 1887: Consumption; Pneumonia and Bronchitis; and Other Acute Lung Diseases. The disease types are further broken down racially: "White" and "Colored,” with red symbols for white and blue symbols for colored.
The second map shows the locations of individual fatalities by city block for five zymotic diseases in Washington in 1887: Typhoid Fever, Malarial Fever, Scarlet Fever, Diphtheria and Diarrheal Diseases.
The third map is of total deaths by city block and by race. (At that time, the white mortality rate in Washington was 17.74 per 1,000; for blacks, it was 31.15 per 1,000.)
All three maps show block numbers, outlines of principal federal buildings, and parklands. Uncommon. [ICN 7639.2].
