In the vascular trabecula of thespleen (fig. 7) the collaginous fibers of the blood-vessels acquirea typical brown while the close network of reticular fibers take onan intense black and have a characteristic, either somewhatregularly spiral, or a reticular course, very different from theirregularly wavy collaginous Fig. 7 A vascular trabeculum of a childs spleen. The blackened ofreticulum (r) show clearly in contrast to the collaginous fibers (c/) which in the sec-tion are a golden brown. The reticulum surrounds the vessels and is continuouswith that of the splenic pulp. Bielschowsky stain. Drawn with Edinger pro-jection apparatus, X 255. In the trabecula of the Ijanphatic glands the distribution is notso apparent, the collaginous and the reticular fibers pursuing some-what similar courses, though the latter are apt to be more dis-tinctly spirillar. From careful examination I am led to believethat the relation simulates, in reverse, that already described (seefig. 2) for the elastic fibers, in that it would appear with consider-able certaint}^ in many places that the black reticular fibers areinvested or enveloped by a sleeve or coat of collaginous fibrils,so that the latter fibrils consequently assume a spiral course cor-responding closely to that of th
