The occurrence of hydrogen sulfide in the waters of certain seas, fjords, and basins, as well as the presence of black or "blue" stinking sediments, can hardly escape the notice of any marine scientist. It is not surprising, therefore, that the eminent oceanographer Murray (Murray and Irvine, 1895) concerned himself with the nature of these materials and postulated their bacterial origin even before bacteriologists had described the specific organisms involved.
