    and wedge-shaped, and pressure effects in modifying the shape of bones are also noticed in the upper part of the sacrum. Exostoses may develop about the joints of the displaced vertebrae, apparently elongating them, and the intervertebral joints may be obliterated or the fibro-cartilage may be replaced by an arthrodial joint. The intervertebral disks in the region of the deformity are changed in shape by the pressure, and at times some modification of the articu- lar processes may result from the pressure, but these changes are not uniform. The bony arch connecting the vertebral bodies and the laminae may, as I understand it from the literature, be either thinned and intact, or it may be separated entirely. This may be a unilateral or bilateral condition. Fig. 3. ;Breslau specimen. Instance of slight forward displacement of the fourth lumbar vertebra. (Neogebauer.) The pathological condition may be better understood by a glance at the figures than by any discussion, however lengthy. The amount of displacement obviously varies within very wide limits, and with it the clinical phenomena must vary also. So marked a change in this region of the vertebral column, where the curve is so sharp, results, of course, in a marked disturbance of equilibrium, and the symptoms vary as the direct outcome of the mechanical condition. The posterior superior iliac spines are
