curves southwest of Bermuda are all approximately parallel, though 
with slight variations in the middepths, and especially near the 
surface. Between Bermuda and the Chesapeake (fig. 3) there are 
great variations in temperature station to station, between 700 and 
1,400 meters, though the temperature was comparatively uniform at 
1,800 meters and between 700 meters and the surface. This was 
also the case, though to less degree, north and northeast of the Ba- 
hamas (fig. 6). On the whole the middepths were warmest

Fig. 3—Temperature sections between the continental slope off Chesapeake Bay and Bermuda, stations 
10163, 10171, 10177; and Challenger station 37, 40 miles west of Bermuda, April 24, 1878 (....--). 
west of Bermuda (station 10177), coldest north of the Bahamas 
(stations 10210-10212) and in the northeast Providence Channel 
(station 10196), if we omit for the moment the very much colder 
water over the continental slope. In the upper layers, between, say, 
300 meters and the surface, the Antilles water was warmest, this rela- 
tionship of the various stations to one another being more clearly 
revealed by the profiles (fig. 11, 12, 15) and charts of temperature 
at different levels (fig. 17, 18, 20).
