There is the usnal retrograde metamorphosisto cheesy degeneration, and very frequently liquefaction andabscess formation follow. In cases of moderate severity that come to autopsy duringthe progressive stage of the disease, one finds, usually, on divid-ing the thickened tissues in front of the spine, a cavity thewalls of which are lined with granulation tissue in variousstages of degeneration, and containing puriform fluid. Theadjoining vertebral bodies present a worm-eaten appearance,and one or more of them is partially destroyed. Small frag-ments of necrosed bone, bone
