THE DISTINCTIVE DIAGNOSIS BETWEEN EXTERNAL AND INTERNAL INGUINAL HERNIAE, THE TAXIS, SEAT OF STRICTURE, AND THE OPERATION.
Both herniae compared as to position and structural characters. The co-existence of both rendering diagnosis difficult. The oblique changing to the direct hernia as to position, but not in relation to the epigastric artery.
