Fig. 3 shows an atrophic arthritis in which the car- tilage is atrophied, but it is to be noted that the bone salts have been washed out so that the bones appear very thin. Fig. 4. A normal knee is presented for contrast with Fig. 5 in which joint the cartilage is atrophied so that the bones are in actual contact. Fig. 6 shows a later stage of the atropic process 76 CLASSIFICATION AND TREATMENT OF RHEUMATISM. when the cartilage has practically disappeared and bony anchylosis has actually taken place. Fig. 7 shows the overgrowth of bone or hypertrophy at the upper border of the patella and also along the edges of the joint surface of the fermur. Fig. 8 shows the two rows of joints in the lingers with the cartilage atrophied and bone destruction taking place. In the terminal joints the lipping of the bone at the sides is apparent, thus showing the mixed type. Fig. 9 is the picture from a demonstrated general infection with multiple joint involvement. Fig. 10 shows the ultimate stage in an infectious arthritis. Fig. 11 shows a wrist joint involvement from a gon- orrhoea. Fig. 12 is interesting when compared with Fig. 14, a gouty elbow, and also that one of the joints might be considered (from the X-ray alone) a Charcot joint, but here again is a case of known infection. Figs. 13, 14, and 15 are all from one patient who has a (demonstrated) gout. There were tophi in the ears and he could write on the blackboard with the fingers, there was so much urate of Soda deposited in crystals. Fig. 16 was also a demonstrated case of Charcot joint in a man suffering from Tabes. Fig. i. Villous Arthritis.
