My use of the various filigrees in twenty-two cases has led to certain definite conclusions with reference to the mechanical side of the question.

The accompanying illustration will serve well to give an idea of this filigree, which I devised more than five years ago, and which I have used since that time with growing enthusiasm. To demonstrate the firm hold of new-formed scar tissue on the loops, I can do no better than
