found that the surface temperature had dropped from 59° to 50.5°; 
the bottom water on the contrary, had risen to 49.2°, the entire drop 
taking place within ten fathoms of the surface. 
Temperature sections from Cape Ann toward the Bay of Fundy, 
exhibit a gradation similar to that seen on the line Cape Ann—Nova 
Scotia, the curves growing progressively straighter and straighter

tions 2, 23, and 24; Stations 33, and 35 with Station 29; Station 39 
is intermediate. 
It is interesting to compare the temperature conditions over the 
- three off-shore banks which we visited, Platt’s, Jeffrey’s, and German, 
(fig. 14) with one another and with those of the deep basins. The 
first is about fifty miles northeast of Cape Ann. The surface tempera- 
ture here was 64°, the bottom reading in 45 fathoms, 40.8°, and its 
temperature curve (fig. 14) is almost precisely identical with that of 
Stations 2 and 11. This, of course, shows that the bank had no dis- 
turbing effect on the water above it. On Jeffrey’s Bank, some thirty-
