  "title": "Nightingale 1858: every printed rate recomputed",
  "description": "Every annual rate in Nightingale's 1858 Table No. 2 recomputed from its deaths and strength, one row per month and cause (72 rows): deaths, strength, deaths as a percent of strength in that month, our rate (deaths x 12 x 1,000 / strength, rounded half up to one decimal), the printed rate and the difference. Each row also gives the sum of that month's three printed rates and, for the 15 months whose label we could read, the all-cause figure printed on the folding plate Diagrams of the Mortality in the Army in the East in the same copy.
