6 sept 1854 año - Snow Concludes His Case

Descripción:

Snow draws maps of the locations that the victims live and where their closest water pump is located (page 141). He usesFarr's Weekly Returns to prove his theory (Page 150). He also looks for imperfections in the outbreak such as the brewery and the factory that should have been affected but didn't (Page 154).
