Case from the case-book of the SATTERLEE HOSPITAL, West Philadelphia, Pennsylvania, Surgeon Isaac I. Hayes, U. S. V., in charge. Autopsy made by Dr. Joseph Leidy, Professor of Anatomy in the University of Pennsylvania. At the time of the organization of this hospital a number of the leading teachers and medical practitioners of Philadelphia volunteered their services as ward physicians, and accordingly received contracts as acting assistant surgeons. To Dr. Leidy was assigned the task of conducting the autopsies, and a report of the results was forwarded by him, at the time, to the Surgeon General. This report was accompanied by a number of valuable pathological specimens, which have been preserved in the Army Medical Museum. . . . [Many] patients were sent to Satterlee hospital from the Army of the Potomac . . . and had contracted their disease . . . during the ill-fated Peninsular campaign.
