ABSTRACT
The black material seen in paraffin preparations of tissues fixed with osmium tetroxide is not merely reduced osmium. The lipid is still present in combination with osmium. Osmicated lipid globules are insoluble in chloroform or benzene. They regain their solubility in lipid solvents when the blackness caused by osmium tetroxide is bleached away.
