    QUESTIONS ON THE FORM OF THE PATELLA. Name each of the facets on the posterior surface, telling on what bony surface it rests and in what position of the knee joint? How do you tell the side to which each patella belongs! MODELING OF THE HIP BONE. Rest the bone en symphysis, with a large pillow of clay under ilium that will hold the dorsum ilii and the posterior surface of the ischium about horizontal. Press out a flat piece of clay of sufficient size and one cm. thick and cut in the shape of the dorsum ilii and posterior surface of ischium. Lay this flat on the board, dorsal surface up, with clay pillows of proper size placed underneath the crest at point of greatest convexity and also under the posterior edge, between posterior spines. This preserves the concavity and convexity of the dorsum ilii. Now model this surface, starting with external lip of crest, marking attachment of tensor fascia femoris, external oblique, latissimus dorsi and gluteus maximus muscles. Make posterior superior spine and posterior inferior spine to the latter of which, part of great sacro-sciatic ligament is attached. Bevel anterior border of ilium and put in anterior superior spine for 'Poupart's ligament and sartorius muscle; put in the anterior inferior spine for rectus muscle and J^- ligament. The notch between them gives origin to part of the sartorius. Finish dorsum ilii, putting in superior, middle and inferior curved lines and spaces for gluteus maximus, medius and minimus muscles; indicate attachment of reflected head of the rectus muscle. Finish the borders of the great and small sciatic notches with the spine of the ischium, attaching the lesser sacro-sciatic ligament. Make superior and posterior bor- ders of acetabulum bulging from this surface and also the pos- terior surface of the tuberosity of the ischium,, to which the hamstring muscles, quadratus femoris and gemellus inferior are attached. Place groove for tendon of obturator externus be- tween acetabulum and the tuberositv of ischium. Now turn the copy and rest it on dorsal surface on properly made clay bed. Note that in the pattern bone the pubis and ramus of the ischium stand at right angle to the ilium. Build up inner surface of the ischium and spine, the former attaching
