north of New Zealand and near the Galapagos 

 Islands, and in the Indian Ocean 44° F. 

 in the western portion of the Arabian Sea. 



At a depth of 900 fathoms the highest 

 temperature (42° F.) is still in the North 

 Atlantic to the west of Gibraltar, from which 

 the temperature steadily falls westwards in 

 the same manner as at lesser depths, but only 

 to the extent of two degrees. In the South 

 Atlantic temperatures are relatively higher, 

 and in the Pacific there is a tendency towards 

 an equalised temperature more than in any of 

 the other oceans. 



At a depth of 1500 fathoms the highest 

 temperatures are : in the North Atlantic 

 88° F., in the South Atlantic 37-5° F., in the 

 Indian Ocean 37° F., in the North Pacific 

 36-5° F., and in the South Pacific 36° F. 

 The North and South Atlantic have nearly 

 the same temperature, while the Indian Ocean 

 is now the coldest ocean, a large portion 

 being below the mean, due evidently to an 

 underflow from the Antarctic. 



At a depth of 2200 fathoms the temperature 

 of the North Atlantic is everywhere above 

 the mean, observations at fifty-five stations 

 giving an average of 36-4° F., or 1-2° above 

 the mean. Over the whole of the South 

 Atlantic to the south of latitude 10° S. the 

 temperature is under the mean — slightly on
