What is actually true about Snow’s 1854 cholera map?
Hints
- The map served an argument its maker was already making.
- Its force came from the exceptions, not the cluster.
Show the answer
- A. Snow already believed cholera was waterborne before drawing it
- C. Its power lay in anomalies, the brewery workers, the widow across town
- D. The outbreak was already declining when the pump handle was removed
Why
The map was a rhetorical instrument in an argument Snow was already having. It did not find the answer, it made a spatial argument checkable, which is a different and more useful thing.
