I shall consider thisphase of the subject in a later paper. At this time it is sufficientto say that I consider the fibers referred to to be collaginous intype. One must therefore finally emphasize the fact that in wellrecognized portions of mature tissues elastic fibers in the silveredpreparations remain entirely colorless while reticular fibers RETICULAR AND OTHER CONNECTIVE TISSUES 285. ^1 \i ?^^^
