    an inner surface; the outer is called dorsum, and may be said to be irregularly convex: it is marked by emi- nences and depressions indicative of the attachment of the three powerful glutaei muscles. The chief extent of the inner surface is concave and smooth, and is called the venter. The lower portion, the base or body, is the thickest part of the bone, and enters largely into the composition of the acetabulum,b a cavity for the reception of the head of the femur,—in conjunction with which it forms the hip-joint. Just above the base the bone nar- rows into a kind of neck, from which springs the ala or wing* rising obliquely upwards, outwards, backwards, and forwards, to protect and support the lower abdo- minal viscera. The ala terminates superiorly in a ridge, running along its whole extent, called the crista ilii, crest or spine of the ilium.c This ridge is tipped with a deep layer of cartilage in the child, as is shown in the first cut. To different parts of the crest are attached the oblique and transverse abdominal muscles, the latissimus dorsi, the erector spinae, and the quadratus lumborum. The crista ilii ends both anteriorly and posteriorly in a jutting prominence, to which the term spinous process is ap- plied ; beneath each of these prominences there is a sligbt sinuosity; and below them, again, another jutting point of bone, also called spinous process: so that there are four spinous processes belonging to the ilium; an anterior su- perior ,d an anterior inferior,e a posterior superior/ and a posterior inferior.8. From the anterior, powerful muscles take their origin. The anterior superior spinous process gives attachment to one end of Poupart's or Gimbernat's ligament; to the tensor vaginas femoris, and the sartorius muscles. From the anterior inferior arises the longer portion of the rectus femoris. Into the posterior are in- serted strong ligaments, which bind this bone most firmly to the sacrum. Below the posterior inferior spinous pro- cess there is a considerable sinuosity or arch,h forming,
