{"value"=>"<p>Materials supporting E.B. Elliott's work at the Bureau are often identified as covering a fifteen month period in two segments: the nine months starting June 1861 up to and including February 1862, and the next six months up to and including August 1862. Data for June 1861-February 1862 was analyzed by E. B. Elliott and summarized in Sanitary Commission Document No. 46, published in 1862. Further analysis for the six month period from March through August 1862 was presented in Elliott’s On the Military Statistics of the United States of America (1863), which also covered sickness in the Army of the Potomac for a later period up to April 1, 1863. Aside from any interim work done by T.J. O’Connell and staff following Elliott’s departure for Europe in the summer of 1863, original data for August-September 1862 onward was compiled and/or tabulated under B.A. Gould's direction, beginning in late 1864. See Minutes of the U.S. Sanitary Commission for October 28, 1864 (Washington, D.C., 1865), p. 207; Gould's Report of the Actuary (1867); and his Investigations in the Military and Anthropological Statistics of American Soldiers (1869).</p>"}
