It is the only trulyphysical law observed in the mechanical support of the uterus, which atthe same time corrects the displacement and attempts to cure it perma-nently. The parent instrument of this variety is the original closeddouble lever pessary of Hodge. It is still used in many cases, particu-larly where the vagina is large and roomy, with dilated walls and patu-lous orifice. The broad anterior bar of the pessary rests against the pu-bic bones, and aids its retention. In this case the fulcrum, or rather.

As a supporter for a pro-lapsed and retroverted uterus, this broad pessary is often very serviceable,correcting both displacements. The open lever pessary, in which the anterior cross-bar is wanting, isno longer used, because the two points are liable to injure the anteriorvaginal wall. 342 A TREATISE ON MINOR SURGICAL GYNECOLOGY. But the Hodge pessary is liable to turn in the vagina, so as to lie diag-onally or transversely. To obviate this Dr. Albert H. Smith, of Philadel-phia, modified the original Hodge by lengthening it, to conform more to theshape of the vaginal canal, and by making the anterior arch more pointed, soas to resemble a beak. This pointed extremity reaches entirely or almost tothe pubic arch, but never under or beyond it. A Smith pessary, whichprojects beyond the pubic bones,
