Book 1 — Chapter XIII
Arthur John Brock translation
Chapter XIII
Failure of Asclepiades to understand the functions of kidneys and ureters. His hypothesis of vaporization of imbibed fluids is here refuted. A demonstration of urinary secretion in the living animal; the forethought and artistic skill of Nature vindicated. Refutation also of Asclepiades’s disbelief in the special selective action of purgative drugs.
