The Measurement of the Capacity of the Pelvic Cavity.—The capacity ofthe pelvic cavity must be estimated by vaginal examination. There is no plan by which accurate meas-urements can be made. It issufficient to estimate the sizeand the shape of the pelviccanal by palpating the lateralv. walls of the pelvis; by deter-// mining the curve, perpendicu-\\ larly and laterally, of the sa-il crurn; by noting the height•/ of the sacro-sciatic notches,.
