further evidence of the banking up of abyssal water, and of water 
from the middepths, against the slope. The curves show that the 
salinity was rather higher in the middle of the profile than either 
farther west or farther east, instead of lower, like the temperature; 
but on the slope of the Bermudas salinity, like temperature, sug- 
gests a shght upwelling of abyssal water—i. e., it is only in the mid- 
layers that salinity and temperature fail to agree. Below about

Fic. 10.—Salinity sections east of the Bahama Bank; stations 10193, 10210, 10212, and down to 1,800 meters 
in the northeast Providence Channel, station 10196. 
1,800 meters abyssal water with practically uniform salinity (34.9°/.,) 
was encountered. 
The upper layers of water were colder over the southern slope of 
the Bermuda Bank (station 10179, fig. 13) than over the northern 
(station 10177, fig. 11), the difference being greatest (3°) at 1,200 
meters; but below 1,400 meters the northern slope was the coldest. 
Along the line running southwest from Bermuda (fig. 13) the 
surface layers grew gradually warmer toward the south, the curve 
for 15° dipping from 550 to 700 meters, while near the surface the
