The physiology and anatomy of the kidney are relatively well known due to the large number of investigations which have been carried out. One aspect of kidney function which has been neglected is that dealing with the excretion and reabsorption of biocolloids. In many disease conditions large quantities of a great variety of proteins may be excreted in the urine. The nature of the pathological changes involved in many of these diseases is not understood. One of the reasons for this lack of understanding is the absence of direct evidence concerning the normal processes involved.
