Summary The kidneys of low and higher animals were investigated with microelectric methods and chiefly with vital staining. These methods and others as well demonstrate conclusively that the kidneys are also electrical organs with a complicated electrocytology. Among a plurality of chemical and electrical forces there is a strong electric field of preponderantly positive nature in the cortex and a more negative one in the medulla, the ureter and in the wall of the urine bladder. The bulk of the blood filtrate, some 99%, is electroosmotically shifted through the wall to the circulations of blood and lymph and a very small part, less than 0,1%, as ions electrolytically through the wall to the blood capillaries. Mitrochondria play a great role in the organs as formerly, assumed, as Kisch and other authors demonstrated by electron micrographs. This is demonstrated for they kidney by Fig. 28–14, p. 462 of Maximov-Bloom, Textbook of Histologie, Philadelphia 1957, 7th edition, the mitochondria are the blackest structures among all tissus tubules only grey: U.
