    f INDIAN NOTES spaces between the arches of the former and the edges of the entrance into the sacral canal. The latter is laid open along its full extension, as shown in fig. 12, causing a complete longi¬ tudinal gap whose edge-to-edge width attains 10-17 iTirn* This condition of rhachischisis sacralis prevailed apparently during life, since the edges of the gap are smooth, showing no sharpness from breakage in the skeletal state. The ribs (vii-xii) are likewise completely fused with their vertebral articulations, both in the vertebral bodies and in the transverse processes. Finally, the left hip bone through the greater extent of the sacroiliac articulation, is fused with the sacrum; in the lower part, however, the articulating edges are separated by a very narrow fissure having the appearance of an extended rift in the diffuse osseous growth. This is the most extreme case of arthritis deformans known to the writer. [56]
