By the death of Frederick Gordon Pearcey at Newport, Mon., on Jan. 26, at the age of seventy years, there passed away the last survivor of the scientific staff of the Challenger Expedition. Mr. Pearcey was attached to the biological laboratory of the Challenger in 1872 as taxidermist and general assistant, and on the completion of the voyage he assisted Sir Wyville Thomson and Sir John Murray in the Challenger Office at Edinburgh, acquiring great skill in identifying species, especially of Foraminifera, on which he wrote several papers. He devised methods for cutting microscopical sections of marine deposits, and became proficient in all branches of practical oceanography and museum arrangement. His alert intelligence and obliging disposition made him a favourite with all contributors to the Challenger memoirs. When the last of the Reports was published he worked for a time at the Marine Biological Station at Granton and at Millport on the Clyde. In 1889 he went to the Owens College Museum in Manchester. Nine years later he joined the staff of the Scottish Fishery Board, but in 1905 he returned to museum work, going to the Bristol Museum as assistant curator of zoology; there he remained until his retirement after the breakdown of his health last year.
