    "abstract": "The use of a polarograph in the analysis of photographic fixing baths for aluminum alum, chrome alum, sulfite, and silver is described. A Fisher Elecdropode was used in this work. The polarographic method is shown to have an accuracy within 5 per cent for each of these 4 materials, which is satisfactory for photographic purposes. The reproducibility of the method is shown to be within 3 per cent. This method of analysis for aluminum alum, chrome alum, and silver is in use in this laboratory instead of the gravimetric method which is considered more cumbersome and time consuming. The polarographic method of analysis for sulfite has also been found more convenient in this laboratory than the previously used volumetric method.",
