The development of clearance methods for measurement of glomerular filtration and tubular reabsorption.

This essay looks at the historical significance of four APS classic papers that are freely available online: Jolliffe N, Shannon JA, and Smith HW. The excretion of urine in the dog. III. The use of non-metabolized sugars in the measurement of the glomerular filtrate. Am J Physiol 100: 301-312, 1932 (http://ajplegacy.physiology.org/cgi/reprint/100/2/301). Shannon JA.

The renal tubular reabsorption of glucose in the normal dog. Am J Physiol 122: 765-774, 1938 (http://ajplegacy.physiology.org/cgi/reprint/122/3/765). Shannon JA, Farber S, and Troast L.
