2. The 5^th lumbar vertebra belonging to a subadult female aged about 16 years (T.50; S.43-84 B). The two laminae are not joined posteriorly to form the spine; a case of spina bifida (arrow).

3. Four separate teeth belonging to an adult male about 45 years of age (T.50; S.70 C). Notice the calcarious deposits at the roots of the teeth (arrows).

4. Lateral view of a skull of an adult male aged about 45 years (T.50; S.70 D). Notice the flat occiput and the rounded contour of the skull (arrow).

5. The 7^th cervical vertebra belonging to an old adult male over 50 years of age (T.55; S.28-50). The upper surface of the body shows marked degenerative changes in the form of pitting (arrow).

6. Lateral view of fused lower thoracic vertebrae belonging to an old adult male over 50 years (T.55; S.28-50). Notice the ossified anterior longitudinal ligament (arrows); a case of dystrophic idiopathic skeletal hyperostosis (DISH). Notice also the projecting osteophytes at the upper and lower margins of the bodies of the vertebrae (arrowheads).

7. The 2^nd and 3^rd lumbar vertebrae of an old adult male aged over 50 years (T.55; S.28-50). The anterior surfaces of the bodies of the vertebrae show marked trabeculations (arrows).

8. Two broken parts of the parietal bone of a skull belonging to an old adult male over 60 years of age (T.56; S.50-79 A). The cut sections of the bones show that they consist mainly of diploe whereas the outer and inner tables are no more distinguished (arrows).

9. The lower end of the left humerus of an old adult male over 60 years of age (T.56; S.50-79 A). The articular surfaces of the trochlea and capitulum show marked degenerative osteoarthritis in the form of pitting together with elevated areas of bone formation (arrows). Lipping of the edges of the articular surfaces can be seen (arrowheads).
