✦ Synopsis

Organic selenium compounds are of theoretical and practical interest due to the similarity of selenium to sulfur in its chemical behavior. Selenium, either as the free element or in combination, exhibits important physiological effects and marked toxicity when introduced into the animal organism (H. C. Dudley, U. S. Public Health Reports, 53, 281 (1938)). Its highly injurious properties have been strikingly demonstrated in the "alkali disease" of Western cattle.

Comparatively few micromethods are known for the analysis of selenium in organic compounds where selenium is one of the major constituents. The procedures of Wrede
