Summary
The autofluorescence of the kidney has been investigated in nine species of teleosts, comprising marine, euryhaline and fresh water forms. Fluorescence was studied in fresh spreads of the kidney in all species; and in addition the living kidney was observed in situ in the sculpin and eel. The fundamental fluorescent tone of the renal tubules is a bluish-white, usually of rather low intensity. The fluorescence is for the most part so uniform that the attempt to identify, by distinctive fluorescence, the known subdivisions of the nephron in particular species has been almost entirely unsuccessful. Certain exceptional fluorescent pictures which have been observed in the renal tubules are described. It is concluded that, of the two lyochromes demonstrated by Ellinger in the kidney of the frog and rat, one is not present, but the other is quite possibly present at times, in the kidney of teleosts.
