{"value"=>"<p>The documents in this group were originally rolled together and labeled \"Deductions from abstracts of the monthly returns of medical directors respecting the sick and wounded on the armies of the United States.\" They consist of printed forms, each with two sections entitled “Abstract of monthly returns of medical directors respecting the sick and wounded in the armies of the United States” and “Deductions from abstracts of the monthly returns of medical directors respecting the sick and wounded in the armies of the United States,” containing various tabulations of data for the period collected. All entries are in ink; Army of the Potomac and Bank’s Corps each have an additional draft copy in pencil.</p> <p>The data on a single form presents sickness, mortality, and unit strength, typically for one corps or military department. Within the abstract section, the total number of cases is listed under the appropriate sickness and mortality column headings. Within the deductions section, the total number of cases are taken and made into percentages per 1000 soldiers. Data entered in each column are for the months or seasons stated in the far left column.</p> <p>While some information found on these forms can also be found on the “Copies of Medical Reports” (i.e. data under column heading “Taken sick or received in hospital during month”), most of the data is unique to these abstracts and is likely obtained from an original source other than the “Copies of Medical Reports”.</p> <p>Draft copy for Banks' Corps has abstracts and deductions on two separate sheets.</p>"}
