The greater portion of the "work is undoubtedly accomplished by the " bonesheath," a fairly tough but very vital membrane which invests the" bone. This bonesheath not merely takes upon itself the grtater share of bone repair in the case of a-break, but is likewise responsible for restoring large portions of bone when these, from injury or from an operation, consequent upon the removal of diseased portions, have been removed.
