His condition had been investigated clinically and biochemically in great detail and had previously been reported by Fischer, Gunther and Weiss. Borst reports the gross and microscopic observations of the autopsy. Grossly, there was porphyrin discoloration or "hemosiderosis" of the skin and the entire skeleton, spleen, liver, lymph nodes, pancreas and kidneys, and histologically of practically all of the tissues of the body.
