The changes are progressive, retrogressive or a combination of both, depending on the predominance of passive or active hyperemia. Alternations of active and passive congestion are more influential in upbuilding than the steady continuation of either. I1 have seen a similar pathologic condition of the ribs in more than 200 cardiovascular cases (fig. 1) of long standing. The changes in bone cells and the modification of matrix and marrow were similar to those in the cases I describe here.
