According to certain authors, the canal system of the kidneycomes from the ureter, according to the usual form of glandular to others the kidney develops from two separate formations:the medullary substance and the collecting tubules from the ureter, thecortical substance and the twisted tubules from a specific formation, thekidney blastema: Ovary.—In embryos of eight to twelve millimetres the celom epi-thelium on the inner side of the Wolffian body becomes thickened. This constitutes the germinal fold, which has been outlined distinctlyfrom the stroma of the Wolffian body. Through a decided increase in thecells of this germinal epithelium and a change of a large part of thesecells into primitive ova, the parenchymatous ovary is formed. Connec-.

(Nagel.)1, External layer of primary ovary (later germinal epithelium of the ovary) ; 2, com-partments of ova; 3, stroma (vessels). tive-tissue cells and vessels grow from the stroma of the Wolffian bodyinto the germinal epithelium, dividing it into compartments. These com-partments consist of primary ova and germinal epithelia, and are dividedinto constantly smaller compartments by the growth of connective-tissuestroma. Finally, we have primary ova surrounded by a layer of germinalepithelium, the so-called primary follicles. The superficial layer ofthe germinal epithelium remains as a simple layer of cylindrical epithe-lium covering the ovary. Most authorities believe that the follicle epithe-lium is derived from the germinal epithelium. Others claim that itorigi
