Note.—The front of the bones are represented in this and the two following Plates, as if transparent, so that the head may be seen through them.

Plate XXVII.

This Plate represents the head just entering the upper Strait.

PLATE XXVIII.

At this time the anterior fontanelle can scarcely be reached, but the posterior one is easily to be reached, being in the open passage, on the left side. The head is now fairly within the Pelvic cavity, but still lies across from right to left.

Second Movement, Rotation of the Head.—When the Fœtus is thus brought to the bottom of the Pelvis, its head turns completely round, the back of it being brought to the front, or under the pubes of the mother, and its forehead turned against her Sacrum, as represented in Plate XXIX.
