C. RETICULUM The careful observation of Bielschowsky preparations alsoyields valuable data as to the finer structure of reticular tissueand the relation of its fibrils to the fixed connective tissue cells. The coarser fibers of reticulum may be readily seen and, wheresuch fibers come into relation with the knots of the reticularnet, one can observe these fibrils breaking up into a plexus within,or about, the cells as pointed out by Balabio (08). Somewhat.

The appearance of abrupt endingmight if only occasionally observed, be due to the passage of fibersout of the plane of the section, but it occurs far too often so thatthis certainly is not always the case. The finer fibrils, as well asmany of the coarser ones, appear as single fibrils though becauseof the complete opacity of the impregnation one cannot say thatthis is actually the case. Certainly the larger f
