and irregular. On German Bank, some fifteen miles off Seal Island, 

 Nova Scotia, the surface reading was 50.5°, the bottom 49.3°, the 

 entire drop taking place in the upper ten fathoms, below which point 

 the temperature was uniform to the bottom. These three banks, 

 then, taken in a series, illustrate precisely the same kind of tempera- 

 ture relation as was exhibited by the coast waters passing eastward 

 and northeastward from Cape Ann, but to a more pronounced degree. 

 The serial temperatures at Station 31 (Fig. 15) are especially in-
