to those of the male. There, the superior branch supplies the clitoris, while the inferior goes to the vulva and parts in the perineum. (See Appendix E.) The lesser ischiatic nerve passes out of the pelvis with the internal pudic. One of its cutaneous branches curves around the tuberosity of the ischium, ascends to the scrotum, and there divides. One branch is distributed to the inner surface of the scrotum, and to the testis. The external branch goes to its outer side, and both terminate in the integument of the under border of the penis, or, in the female, to the vulva. To sum up, then, we find that the lumbar nerves give some large posterior branches, which are distributed to the loins, the sacrum, and nates; also, that the three musculocutaneous branches give off those that go to the muscles of the lower abdomen, to the folds of the groin, and to the scrotum or pudendum; another branch to the integument of the lower abdomen, and another to the skin of the upper and inner thigh. A genito-crural nerve-branch also goes to the integument of the scrotum, the groin, and the thigh. Then the sacral nerves give branches to parts in the vicinity of the coccyx ; also posterior branches to ramify the muscles and integuments of the nates. Of these are the hemorrhoidal nerves to the rectum, the vesical to the bladder, the uterine and vaginal nerve branches to the vagina and uterus. A branch of the inferior gluteal goes to the perineum, and the integuments of the posterior parts of the thigh. Then there is the pudic nerve to the perineum, and to the penis, or vulva. The most important neuralgic spots in this region are, first, a series of points along the side of the spinous processes, and but a little removed from the median line where the posterior branches of the lumbar and sacral nerves emerge from their bony passage — the former pierce the lumbo-sacralis, to become distributed to the integument over them; and again, a neu- ralgic extent along and near to the median line over their ultimate cutaneous distributions ; and again, a neuralgic spot at the posterior part of the crest of the ilium, where some of the lumbar branches pass over its edge very superficially, and 39*
