Landauer investigated these cellsin many species of vertebrates and also in man and con-cluded that the convoluted tubules and the ascending limljof Henles loop are lined by cells which are sharply out-lined and provided with longitudinal folds, whichinter-lock, and it is these folds that give these cells the striatedappearance (rod structure of the authors). Zimmermanndescribes in detail the epithelium lining the different por-tions of the uriniferous tubules, especially emphasizing thepresence and relations of the Centralkorper or Ceutral-geissel in these cells. He also distinguishes the darkercells showing striation and brush-like border and cellswhich are large and clear, the structure of which isquite indistinct. He describes fine densely placed fibres.
