I repeat that the fact just stated in general terms is incontestable,inasmuch as it obviously refers to the axis of the cavity: but Xaegelegoes beyond this, and pushes his conclusions much further than thefacts of the case warrant, when he says that the sagittal suture is nearerthe promontory of the sacrum than the symphysis pubis, and that thebiparietal measurement can never during labor coincide with the planeof the pelvic entrance. I may mention here that, although I beganmy study of the suhject with a firm conviction that Xaegele was rightin this particular, I have been step by step driven to the conclusion Fig. Fig. 199 shows ili great amount of lateral obliquity [qui the horizon) ofthe head advancing in theaxis nf the brim, the centre of the sagittal suture being, although mneh nearer thesaeratm, exactlymidway between the it. montory of that bone and the symphysis pubis, it showsalsohon -luriui:the whole of this stage of labor, the right tuber parietale may bedi scribed, in general terms, a- the1 art w hich drat meets the linger, oraa lowest In the peh Is, adTanclng as it does In the direction ofthe dotted Line parallel to the axis of the brim, [f the bead were in the transverse poaitloa, ti the tuber parietale would be -till more decided, bnt In that ease it won;.. to tli left of tin- middle Line. a b, th plane of the brim meeting the boriion al as angle of 0 at a. o d, the axis of the brim passing through the centre of the sagittal intnre and the eoeeyx, andg the horii >n at d al an i that he is perfe
