Annotated record of the detailed examination of Mn deposits from various ship expeditions in the Atlantic Ocean from 1876 until 1911

The greater part of this Monograph is devoted to detailed descriptions of 1426 samples of deposits from the floor of the Atlantic Ocean stored in the Challenger Office, Edinburgh, which had been collected during thirty-five cruising expeditions between 1857 and 1911. The remaining part discusses the results of the work. The work of examining and describing in detail this abundant mass of material was in progress when the late Sir JOHN MURRAY met his death in March 1914. By that time about three-fourths of the descriptive work had been completed under his supervision. Sir John's trustees arranged for the completion of the descriptive work by Mr Chumley, and this was done in the Challenger Office during the two succeeding years. Later, after he had removed to Glasgow, Mr Chumley prepared the notes discussing the results. The trustees have pleasure in recording, on the suggestion of Mr Chumley, the courtesy of Dr G. W. Lee of the Geological Survey of Scotland, for help in determining many of the rarer mineral particles contained in the deposits.本专题专著的主体内容，详细记述了1857年至1911年间，通过35次巡航考察采集、现收藏于爱丁堡挑战者办公室（Challenger Office）的1426份大西洋海底沉积物样本。其余章节则阐述本次研究的成果。已故约翰·默里爵士（Sir JOHN MURRAY）于1914年3月逝世时，针对这批海量样本开展详细检测与描述的工作仍在推进中；截至其逝世前，在他的主持下已完成约四分之三的描述性工作。约翰爵士的受托人委托查姆利先生完成剩余的描述工作，该项任务于后续两年间在爱丁堡挑战者办公室内完成。此后，查姆利先生迁居至格拉斯哥后，撰写了阐述研究成果的相关笔记。应查姆利先生的提议，受托人特此致谢苏格兰地质调查局（Geological Survey of Scotland）的G·W·李博士（Dr G. W. Lee），感谢其协助鉴定这批沉积物中的诸多稀有矿物颗粒。
