DEFORMITIES OF THE PELVIS 573 terval between the points with the scale. (Extract from the Memoir of M. VanIluevel.) Quite recently (February, 1855), the ingenious accoucheur of Brussels hasstill further improved his first pelvimeters, besides suggesting another, whichappears to me quite as simple, and of more general applicability than the pre-ceding. I therefore think it right to give a detailed description of it. It is simply a pair of callipers (Fig. 89) composed of two branches, one of Fig. Fig. 91. which is fixed, and the other movable. The first, A B, is eleven inches in length,slightly curved, and flattened at its extremity; it is inserted into the vagina for 574 DYSTOCIA. the internal measurement, and bears a hooked ring near its middle, beyond which,is a non-graduated arc of a circle. It articulates below, like an ordinary pair ofcompasses, with the prolongation of a sheath, in which is inserted the lowerextremity of the other branch. The curvature, length, and hooked ring, are thesame as in the small geometric pelvimeter. The second or external branch, c B, may be lengthened or shortened at plea-sure.
