From a depth of 300 fathoms to a depth of 1500 fathoms the 
temperatures in the North Pacific are greatly lower than those 
in the North Atlantic. In both oceans the temperature gradu- 
ally falls for every zone of equal depth in passing from west to 
east, as the influence of the reflux of the equatorial current be- 
comes weakened. The table given on page 368, which is con- 
structed from the same serial soundings which are represent- 
ed graphically in Figs. 100 and 101, shows at once the east- 
ward cooling, and the much greater condensation and accumu- 
lation of warm water in the basin of the North Atlantic. The 
most marked phenomenon of the Gulf-stream, the condensation 
and superheating of the water of the equatorial current in the 
Caribbean Sea and the Gulf of Mexico, and its ejection in a de- 
fined hot stream through the Strait of Florida, has no parallel in 
the Pacific, and the Kuro Siwa must be regarded as represent- 
ing that diffused portion of the reflux of the equatorial current 
which passes northward outside the West Indian Islands. 
On the 26th we sounded in 2650 fathoms. Serial tempera-
