PLATE VII.—a.

This represents the Male Pelvis, to show the difference in structure.

The letters correspond with those in Plate VII.

PLATE VIII.

Section of the Pelvis, to show the shape and connection of those parts not distinctly visible in the full view. The section is made down the middle of the back bone, and through the symphysis pubes, in front. The letters correspond with those in Plate VII.

A. The right Ilium.—B. The Sacrum.—C. The Coccygis.—b. The Os Pubis.—c. The Os Ischinum.—g. The Foramen Magnum.—o. shows the manner in which the coccygis is bent back through labor.

These bones are all firmly bound together by a cartilaginous substance, which is placed between where they touch, and is firmly attached to each one. This union is called a symphysis. The one at front which joins the pubic bones is called the symphysis pubis; the two which join the Ossa Illii to the Sacrum are called the sacro iliac symphyses; and that which joins the Coccygis to the Sacrum, is called the Sacro coccygeal symphysis. The two pubic bones are separated a little in Plate VIII, simply to show them better. The reader will bear in mind that they are naturally connected by the cartilaginous substance which forms the symphysis.
