Fig. 4. Deep transverse saw-section in the femoral shaft of the dog, with slight movement in the gap, when 

 bending the bone. Chondrofibrotic callus formation in the centre of the saw-slot by the influence of discon- 

 tinuous pressure and traction (histolog. section above). Primary bone formation at the ends of the saw-slot, 

 where the amplitude of movement is low (histolog. section below)
