Thehorizontal portions of thepubes have become almostparallel, narrowing, of course,the antero-posterior diameter,and approximating the ex-tremities of the transverse aswell as the oblique diameters,so as to render hopeless anyattempts to extract the child through it alive. It appears to me needless to follow the example of writers whohave reduced the deformities of the pelvis into a sort of is evident that softening of the bones, which may attack the wholeor any part of the osseous structure of the basin, may yield any con-ceivable irregularity of form; and those that I have already spokenof in this article being sufficient to show the Student what is the natureof these deformities; and as he is already acquainted with the meandimensions of the foetus, he may be considered qualified to give judg-ment on questions of obstetrical operations arising under 522 DEFORMED PELVIS. It is necessary that he should be aware of the methods which areadopted for ascertaining the dimensions of the pelvis. As a generalrule, the indicator finger of the accoucheur will scarcely be foundcapable of extending further than three and a quarter inches or threeand a half inches beyond the crown of the pubal arch. It is true that,by the introduction of half the hand, the palp of the indicator fingercan be made to explore a region four and a half inches distant fromthe crown of the arch ; but, as the introduction of half the hand inthe woman not in labor or affected only with the earliest stages oflabor, is so painful as to excite repugnance and resistance on the partof the patient, the vaginal taxis alone is generally preferred. Suppose there should be some suspicion of a deviation of the pelvis—one in which the pubis has retreated towardsthe sacrum, or one in which the promontoriumhas descended towards the symphysis.
