Pus and lymph in the cavity of the joint. Semi-hmar cartilages and' 

 articular cartilages of the femur and patella eroded, with caries of the 

 bones." 



The trochlear surface of the femur is bare, while the 

 surface of the condyles is covered with granulations blanched 

 and shrivelled by the spirit. An aperture in the inner tuber- 

 osity of the tibia (indicated by a rod) passes downwards and 

 forwards from the joint. G. C. 1485.

7. 68. Tubercular Arthritis begrinning- in the Epiphysis 



of the Femur. — Lower epiphysis of a right femur, with 

 upper end of the tibia and fibula, and the patella — macerated, 

 to illustrate the above. 



The femoral epiphysis is excavated and eroded chiefly 

 upon the articular surface of the inner condyle, but partly also 

 upon that of the outer condyle. The cartilage has been under- 

 mined, as if tubercular foci in the epiphysis had gradually 

 extended themselves into the bone as well as towards the joint.. 

 The cartilage upon the outer tuberosity of the tibia, and upon 

 the back of the inner one, is not much affected, but some 

 absorption of the cartilage has occurred on the front of the 

 inner tuberosity, possibly by extension from the femur. The 

 articular surface of the patella has been superficially eroded.

7. 69. Tubercular Arthritis subsiding^.— Bones of a left knee- 

 joint — macerated, shoAving great atrophy of the shafts and 

 alteration of the articular surfaces. The epiphyseal end of 

 the shaft of femur is reduced to a light shell. The epiphysis 

 which has been detached is lightened, but to a less extent. 

 The articular surfaces of both bones are rarefied in many places, 

 while the cartilage has remained at others. The tibia is very
