10. Ischial part of the left innominate bone of an old adult male aged aver 60 years (T.56; S.50-79 A). The ischial part of the articular surface of the acetabulum shows degenerative osteoarthritis in the form of pitting (arrows).

11. Head of a femur belonging to an old adult male aged over 60 years (T.56; S.50-79 A). There is marked degenerative osteoarthritis in the form of pitting (arrows) and new bone formation (arrowheads).

12. Tibial plateau of a tibia belonging to an old male aged over 80 years (T.56; S.50-79 A). There is marked degenerative osteoarthritis in the form of areas of pitting (thin arrow), bony projections (arrowheads) and lipping (thick arrows).

13. Right and left patellae belonging to an old adult male aged above 60 years (T.56; S.50-79 A). Notice the marked degenrative osteoarthritis of the articular surfaces of both patellae in the form of pitting (arrows) and bony elevations (arrowheads).

14. The under surface of a talus belonging to an old adult male aged over 60 years of age (T.56; S.50-79 A). The lower part of the articular surface of the head of the talus shows degenerative osteoarthritis in the form of pitting (arrows) and osteophytosis (arrowheads).

15. The 5^th and the 6^th cervical vertebrae belonging to an old adult male over 60 years of age (T.56; S.50-79 A). The surfaces of the bodies of both vertebrae show degenerative changes in the form of pitting and roughness (arrows).
