The curveof Fig. 9 belongs to Station 110, near St. Paul Rocks; thecurve of Fig. 10 to Station 221, in the basin between Papuaand the Caroline Islands. In the former a surface-current,retaining a nearly uniform temperature of 25° C. down to adepth of 30 fathoms, is joined by a steep gradient to anintermediate current which extends from 100 fathoms to 400fathoms, the cold bottom-stratum being reached at a depth of 00 z < tu o o r rr cc UJ UJ I QC H DC D < O m CO ui III o X ~ 1- o z h c?
