This small book contains five lectures on the following topics: (1) the structure of nuclear material in plants and animals and the metabolism of nucleins, (2) the chemistry of the pigments of the blood and bile, (3) the place of formation of biliary pigment, (4) the production of icterus and (5) the lipoidoses: xanthoma, Gaucher's disease and Niemann-Pick's disease.
The presentation is scholarly and critical; each lecture contains a review which brings the subject up to date by including the more recent contributions. Thannhauser is professor of medicine in Freiburg. He speaks with special authority in the fields of purine chemistry and bile. His "Lehrbuch," a monograph on metabolism and diseases of metabolism, is widely recognized as a masterpiece of medical writing in this field. The "Stoffwechselprobleme" is lacking in a bibliography, much to the disappointment of the reviewers.
