band at station 10165; otherwise the temperature was very uniform 
east of station 10163 above 650 meters, the curve for 15° being 
almost horizontal at that level, to swing up to the surface near the 
land as described elsewhere (p. 47). And, again, the temperature 
was nearly uniform at 1,800 meters east of station 10163. But in the 
middepths there is a very pronounced upwelling of cold water, 
revealed by the curves for 5° and 10°, in the center of the profile, 
between 800 and 1,600 meters. At the western dandward) end of the 
profile all the curves swing sharply upward, showing a very pronounced

banking up of cold water against the continental slope, which need 
be merely mentioned here, being discussed at length on page 47, 
and there was evidently a minor banking up of abyssal water against 
Bermuda below 1,200 meters. Down to the 700-meter level salinity 
(fig. 12) agrees closely with temperature, the curve for 36°/,, 
practically coinciding with 15°, the warm surface water at station 
10164 finding its counterpart in high salinity (86.5°/,.). On the 
continental slope the successive curves for salinity dip, like those 
for temperature, very steeply from west to east—i. e., they afford
