In thecavity, the most note-worthy feature of thefemale pelvis is thediminution in the per-pendicular depth, thesymphysis being in themale nearly double thedepth, while the sac-rum is shorter as wellas broader, and placedso as to offer a moreample concavity. Itwill also be noticed,in looking downwardsand backwards, as isshown in Figs. 10 and11, that three projec-tions are seen—poste-riorly the sacrum andcoccyx, and on eitherside the convergingischial planes, culmi-nating in the ischialspines. These projec-tions, encroaching, asthey manifestly do, oncertain measurements of the lower parts of the pelvis, have, as will beexplained afterwards, a very important bearing upon
