Excerpts from John Syng Dorsey's Elements of Surgery, 1813
These pages give some telling insight into the process of phlebotomy as it related to medicine. In this first page Dorsey is describing the use of blood-letting to treat strangulating hernias. The commentary describes some of the more common sites for bleeding and the fact that volume wasn't always the determinant of the amount removed from the patient.
Page 2 describes the process sof bleeding and gives us an understanding as to the reason why most lancet cases contain numerous lancets.
Page 3 describes the use of German fleams and describes further techniques used in bleeding and selecting sites.
