SUMMAEY OF KESULTS.

The organisms in the tow-nets to-day showed that the ship had entered another 
region, where the organisms had a more tropical character, as shown by the re-appearance 
of Pyrocystis, Ethmodiscus, several species of Copepods, and other organisms. The 
surface temperature, it will be observed, was several degrees higher than at the last 
three or four Stations, 
Station 255 (Sounding 397), Yokohama to Sandwich Islands (see Chart 36 and 
Diagram 19).

Density at 60° F. at surface, 1 '02602 ; 2100 fathoms, 1 '02552 ; bottom, 1 '02569. 
Depth, 2850 fathoms ; deposit. Red Clay, containing no carbonate of lime (see 
Murray and Renard, Deep-Sea Deposits Chalk Exp.). 
At 1.15 P.M. stopped to sound. At 2 p.m. sounded in 2850 fathoms. At 3 p.m. 
obtained serial temperatures down to 1500 fathoms. Lowered second whaler for surface 
collecting, some interesting specimens being procured. At 4.30 p.m. completed temperatures 
and proceeded under steam. Albatrosses still numerous about the ship. 
Honolulu distant at noon, 702 miles. Made good 132 miles. Amount of current 
19 miles, direction S. 5° E.
