    Data on platinum in manganese nodules by a combined fire assay-spectrographic procedure agree reasonably well with data obtained by a fire-assay flameless atomic-absorption spectroscopic method. A plea is made for the contribution of much more data on Pt in these samples for arriving at valid conclusions and for showing their geochemical and economical interest.
