From personal experience I believe Skutschspelvimeter is the best, although I have long ago given up attemptingto measure the internal pelvic capacity with instruments. Quite a new principle characterizes the ingenious invention ofNeuman and The principle involved in the pelvigraphis that of parallel rulers. One arm localizes the various points withinthe pelvis, while the other has attached to it a dial. The various.

I understand that it has not come up to expectation. Certainly itis far too complicated for practical purposes, and this is the conclusioncome to b}T Radiography has not proved of practical value; for although withX rays one can obtain an idea of the general pelvic formation, sofar it has been impossible to make exact measurements of the pelvicdiameters. i Zeit. f.
