meters being only 7°/,. (34.8-35.5°/o. The salinity of the mid- 
depths, like the temperature, was ieheat west of Bermuda, where 
water of 35.2 per cent was encountered at about 1,500 meters; 
lowest north and northeast of the Bahama Bank (Stations 10193, 
10210, 10212) and in the northeast Providence Channel (station 
10196), where water of this salinity was within 700-800 meters of 
the surface. So far as I can learn, no serial salinities have pre-

TEMPERATURE AND SALINITY PROFILES. 
The profile from Chesapeake Bay to Bermuda (fig. 11) is neces- 
sarily interrupted between stations 10161 and 10163, owing to the 
zigzag course followed. (See chart.) On this line water warmer than 
20° was confined to a narrow surface belt just east of the 1,800-meter 
contour on the continental slope (station 10161), with a secondary
