areas of low temperature in all the oceans are 

 found some distance to westward of the 

 continents, apparently proportional to the 

 breadth of the ocean. 



At a depth of 300 fathoms the higher tempera- 

 ture of the North Atlantic as compared with 

 the South Atlantic is even more pronounced 

 than at lesser depths ; the highest temperature 

 in the South Atlantic (48° F.) covers a very 

 small area, whereas in the North Atlantic 

 that temperature covers about half the ocean, 

 and includes two areas within which the tem- 

 perature rises to fully 60° F., in the more 

 westerly one in fact it rises to 63° F., or fifteen 

 degrees higher than anything found in the 

 South Atlantic. The highest temperature 

 in any other ocean at this depth is 53° F., or 

 ten degrees lower than that of the North 

 Atlantic, thus emphatically distinguishing this 

 ocean from all other oceans in this respect. The 

 Pacific Ocean has temperatures above the 

 mean uninterruptedly through eighty degrees 

 of latitude in its western division, and through 

 forty degrees of latitude in its eastern division, 

 the highest temperatures being 51° F., about 

 ten degrees of latitude south 6i Japan, and 

 50° F. the same distance north of New Zea- 

 land. A low temperature (under 45° F.) still 

 prevails in mid-ocean immediately south of 

 the equator. The Indian Ocean at this depth
