organisms was the stomachs of the Salps, whose pharynx, fine as its walls

' The ' Challenger ' Keport on Deep-Sea Deposits ' by Murray and Renard 

 was published in 1891. It was the first attempt to deal with marine deposits 

 as a whole, and became at once the standard book on this subject, a position 

 it occupies to the present day. It was in every sense of the word " epoch- 

 making." The amount of research work entailed in the preparation of this 

 monograph was stupendous ; the detailed microscopic study and chemical 

 examination of thousands of deposit-samples from all parts of the world and 

 from all depths, and of the various constituents contained therein, involved 

 the expenditure of much time and labour. 



The terms applied to the various types of deposits, with the exception of 

 " Gldbigerina ooze," already in use before the time of the " Challenger " Expedi- 

 tion, were devised by Murray on board the " Challenger," some of them being 

 subsequently more or less modified in collaboration with Renard. The 

 nomenclature and classification finally adopted by them have stood the test of 

 time. Notwithstanding the numerous contributions to the subject published 

 in the interval, and the many attempts to improve upon either the divisions, 

 the terms, or the methods originally employed, the " Challenger " Report 

 remains the model and standard upon which all studies of deep-sea deposits 

 are based, and it appears to satisfy all the demands made upon it. This is 

 conclusive evidence of the abundant foresight, care, and scientific precision 

 brought to bear upon the study of the " Challenger " material and of material 

 collected by other ships up to the time of publication. 



Murray came to be recognised as the, authority on all matters relating to 

 the floor of the ocean. His reputation became world-wide, and his advice was 

 solicited on all hands in connection with the fitting out of expeditions and 

 with the scope of deep-sea researches of various kinds. Needless to say his 

 extensive knowledge and practical experience were freely placed at the 

 service of scientists, and many further additions to our knowledge of the sea 

 and its laws are due to his initiative. 



The bottom samples collected by nearly all the surveying ships, cable 

 ships, and oceanographic expeditions of all nations, found their way to the 

 " Challenger " Office in Edinburgh for examination and report, and Murray 

 was thus enabled to bring together a magnificent collection of marine deposits, 

 a collection which is unique in the world. 



One may quote here an appreciation of his work given by the well known 

 Arctic explorer, General Greely. "Writing two years ago in the ' National 

 Geographic Magazine,' of Washington, U.S.A., General Greely says : 

 " Nearly 40 years since, a distinguished scientist, born on the continent of 

 North America, Sir John Murray of ' Challenger ' Expedition and fame, and 

 one of the eight honorary members of the National Geographic Society, 

 considered the mooted extent of South Polar lands and finally outlined their 

 logical continental form as the continent of Antarctica — a fitting and largely 

 accepted name. This great feat of constructive geography depended on a few
