When the breech is the presenting part, one of the ischia (usually the most anterior, or that nearest to the pubis) descends lower than its feUow, and fii'st meets the finger of an ex- aminer. The breech is usually transmitted through the outlet with one hip dii-ected obliquely toward the pubis, and the other toward the sacrum. The shoulders pass the brim with their breadth in the line of the obliqiie diameter, but in passing the out- let, they have their position changed, being then inclined, the one toward the pubis, and the other toward the sacrum: by this inclination the head is brought through the brim with the forehead towards the sacro-ihac synchondrosis, and the occiput toward the opposite acetabulum. The shoidders having been expelled, the face turns into the hoUow of the sacrum, the chin is depressed toward the chest, and so escapes posteriorly; and, lastly, the vertex passes out from imder the pubis.
