If we contemplate it in this light, in the skeleton, it will be discovered that its lateral walls are much higher than its anterior or posterior wall, above which, especially the anterior wall, there is a great vacuity, between the anterior superior spinous processes of the ilia. The- posterior of these vacuities, in the re- cent subject, is filled up by the lumbar vertebrae and muscles, etc., belonging to this region, while the anterior is occupied by the inferior portions of the abdominal muscles, with their fasciae and integuments. The inferior portion of the lumbar division of the spine, to a level with the iliac cristee, and the interve- ning soft parts, together with the muscles, etc., occupy- ing the great vacuity in front (namely, the whole of what is called the hypogastric region of the abdomen), may be justly reckoned as belonging to that division of the pelvis which is called, by obstetrical writers, the greater or false, to distinguish it from the lesser or true, pelvis. This greater pelvis is separated from the lesser by a line, the ileo-pedineal, which is sharp on the supe- rior face of the horizontal branch of the ossa pubis or pectinis, and smooth and rounded on the internal face of the ilia. The greater pelvis, however important it may be du- ring pregnancy (affording, as it does, soft cushions lat- erally for the gravid uterus to rest upon, and a yielding wall anteriorly to allow this organ to gravitate forward), possesses no interest in a paturient point of view, be- cause it forms no part of the canal, through which the fetus is transmitted in childbirth. The observations I shall offer will, therefore, have reference exclusively to the true pelvis, and, this being premised, there will be
