    the spinous process of the ischium, covers the sacro-sciatic liga- ment, upon which it spreads in its course, and passes to he inserted into the extremity of the sacrum and side of the os coccygis. The obturator internus is situated on the inside of the obtu- rator foramen, within the pelvis, and covered by the levator ani. It arises, by very short tendinous fibres, from somewhat more than the upper half of the internal circumference of the obturator foramen. It is composed of several distinct fasciculi, which ter- minate in a roundish tendon, surrounded by muscular fibres, then passes out of the pelvis, through the niche that is between the spine and tuberosity of the ischium, to be inserted into the cavity of the trochanter major. The levator * ani, the last muscle I shall have to mention, is a strong muscle, with glossy tendinous fibres, arising from the pubis. The levator ani takes its origin at the upper edge of the obturator foramen, and continues to arise from the aponeurosis which covers the obturator internus, and all the back way to the spine of the ischium. Its fibres tend toward the perinaeum and anus, so that the muscle closes up partially the outlet of the pelvis, t blood-vessels. In the pelvis we meet with blood-vessels, not to be passed in total silence, consisting of the internal and external iliacs. The external veins and arteries lying upon the sides of the false pelvis, beneath the outer margin of the pso® muscles, while the internal iliacs, spreading over a wider surface, are deposited on the sacro-iliac synchondrosis, in the vicinity of which their pulsa- tions may be sometimes fell. ABSORBENTS AND GLANDS. Accompanying the blood-vessels, as is usual, we have lympha- tics and their glands, and there are some lymphatics with their • Levator:—From Zero, to lift up; hence lifted up; and teiator, a lifter up; be cause it raises the anus. + Burn’s Principles of Midwiferi'. 7th Edit. p. 16.
