INFLAMMA TION. 



after the injury, but only in that portion of the cartilage lying 

 nearest the osseous border. 



With an augmentation of the corpuscles, a retrogression of 

 the bioplasson to the juvenile condition takes place. As red 

 blood-corpuscles are formed out of this bioplasson substance, 

 I have termed it " haematoblastic." This rejuvenescence and 

 transformation into red blood-corpuscles occurs in the inflam- 

 matory process, not only in cartilage corpuscles, but also in the 

 corpuscles of synovial membrane, periosteum, and tendon. (See 

 Fig. 154.)

FlG. 153. CONDYLE OF FEMUR OF AN OLD BABBIT, ON THE EIGHTH DAY 

 OF INFLAMMATION, PRODUCED BY INJURY AT THE LATERAL SURFACE. 

 [PUBLISHED IN 1873.] 



EC, unchanged cartilage ; IN, large medullary space in place of the formerly calcified car- 

 tilage; T, unchanged trabeculaof bone ; IS, medullary space in the bone-tissue, penetrating 

 the calcified cartilage: MS, unchanged vascular canal. Magnified 200 diameters. 



Feeding of Cartilage-corpuscles with Insoluble, Granular Sub- 

 stances. I have injured with the red-hot iron the middle portion 

 of the articular cartilage of the condyle of the femur, and that 

 of the tibia of a young, nearly grown dog, and killed the animal 

 seven days afterward. Around the jagged border of the wound,
