VII.—The Composition and Character of Oceanic Red Clay

Abstract

The chemistry of this not the least interesting of deep-sea deposits, though it has received attention from several investigators in the past, still presents some uncertainties as regards both the analytical composition of the material and its chemical nature. It has therefore been suggested by Sir John Murray, to whom directly or indirectly all our knowledge of Red Clay is due, that the subject might with advantage be reopened from the chemical standpoint. The results of this revision, which was carried out in the Challenger Laboratory at Edinburgh, are set forth and discussed in the ensuing pages.
