nodules, with a few other invertebrates, seemed to be all that lived at these 
great depths, in 2500 to 2900 fathoms, far away — say from 700 to 1000 
miles —from the nearest land. 
The bottom temperatures of the deep Moser basin varied between 34.6° 
at 2628 and 2740 fathoms, to 35.2” at 2440 fathoms, and 35° at 2475 
fathoms, about 176 miles from the Marquesas. At Station 23, off the 
Marquesas, in 1802 fathoms, the temperature was 35.5. 
Owing to the failure of many of our deep-sea thermometers, we were not 
able to make any satisfactory serial-temperature observations. At Station 
11, lat. 14° 38’ N., long. 136° 44’ W., in 2646 fathoms, we obtained : 
79° at surface. 48.9° at 200 fathoms.

These temperatures are somewhat higher than those obtained by the 
“Challenger” in similar latitudes on their line to the westward of ours 
between the Hawaiian Islands and Tahiti. At Tahiti a temperature of 
40° is found to vary between 500 and 600 fathoms, off Hawaii a temper- 
ature of 48° obtains in 224 fathoms, at Hilo 40° was found in 400 fathoms, 
much colder than on the eastern lines. 
The temperatures of the bottom between the Marquesas and Paumotus 
were 34.9° at 1932 fathoms, 35° at 2456 fathoms and 2451 fathoms, and 
35.1° at 2527 fathoms. 
We did not take any bottom temperatures between the Paumotus and 
Tahiti. 
Our deep-sea nets not having reached San Francisco at the time we 
sailed, we limited our pelagic work to surface hauls, of which we generally 
made one in the morning and one in the evening, and whenever practi- 
cable, some hauls with the open tow-nets at depths varying between 100 
and 350 fathoms. The results of these hauls were very satisfactory. The
