OCEANOGRAPHICAL INVESTIGATIONS 17 



being in very deep water, including the deepest cast hitherto 

 recorded, viz. 5269 fathoms, in the vicinity of Guam Island in 

 the Ladrone group. The deposit-samples brought home were 

 examined by Flint, ^ who records many distinct patches of 

 Diatom ooze within the tropics, but Murray has examined these 

 samples, and declares them to be identical with what he has 

 called Radiolarian ooze ; the frustules of the large Coscinodiscus 

 rex are, however, very numerous in these deposits. 



In 1899-1900 the 

 U.S.S. "Albatross" 

 carried on oceano- 

 graphical observations 

 throughout the tropical 

 portions of the Pacific, 

 under the personal 

 direction of Alexander 

 Agassiz,who issued the 

 scientific results in a 

 series of profusely illus- 

 trated memoirs, under 

 the auspices of the 

 Museum of Compara- 

 tive Zoology, Cam- 

 bridge, Mass. 



In 1 899-1 900 the 

 Dutch steamer " Sib- 

 oga " investigated the 

 oceanographical condi- 

 tions in the seas of 

 the Dutch East Indies. 

 Though limited to such 

 a circumscribed area 

 the observations are of great value, and the results are being 

 issued in English, German, or French, under the editorship of 

 the leader of the expedition. Max Weber of Amsterdam.
