The cells of the spleen are proliferated from a peritoneal thicken- ing, which may be compared in this respect to the germinal epithelium. It is recognizable at ninety-six hours, and the mass formed by its proliferation grows rapidly, forming a very consid- erable projection into the left side of the body-cavity above the stomach, at six days (cf.

Other abbreviations as in Fig. 195 According to Choronschitzky, the peritoneal cells invade the neighboring mesenchyme, and, spreading through it, form an ill- defined denser "area, the fundamental tissue of which is therefore mesenchymal. The meshes of the latter are in immediate con- tinuity with the vena lienalis, but the vascular endothelium is.
