A system of surgery : theoretical and practical . he laminse, &c., and consequently (in agree-ment with the law that wherever physiological energy or growth is most active,there is the greatest proneness to inflammation), the bodies are more liable to inflam-matory change than the laminee, &c. As to which of the vertebrae aie most frequently affected opinions still differ,however. Billroth states that from his own statistics the starting-point appearsmost often to be the sixth, and next to this the fifth, seventh, and eighth , on the other hand, regards the last dorsal and first lumbar vertebrae asmost commonly affected, and from my own observation I am inclined to regard thisas nearer the truth. In fact, the disposition to disease appears to diminish as weascend the column, morbid change being least often met with in the cervical region.

S)\ows also that the starting-point may be on theposterior aspect of the bodies (6), which could not be affected by violence without injurj at the same time to theanterior part. The dark lines at either surface of the softening spot (6) indicate the inflamed area of the bonearound. The anterior part of the inter-vertebral disk- (6) is healthy. The relations of both the anterior andposterior common ligaments to the broken-down material is well seen, as also that of the cord. In this we have only another aspect of the general law just stated. For it has beenestablished that growth of the spine is most rapid in the lumbar region, less so inthe dorsal, and slowest of all in the cervical. The same law, too, applies to the ageat which inflammatory changes are met with here. In by far t
