The temperatures of the water well in on the Bank, as represented 

 by the position of stations -12-1 and 425, registered 2.5° to 2*" ex- 

 cept at the 16-meter (9-fathom) depth, at which it was 0.6°. The 

 presence of this cold layer wholly cut oft' by warmer surroundings 

 is uncxplainable, and it is feared the thermometers registered an 

 incorrect reading at this time and place. 



Off'shore, corresponding precisely in position to the salty water 

 mass described in the salinity discussion, lay water warmer than 12°. 

 It presented a more or less vertical face toward the Arctic water 

 along the slope in a position similar to the salty water noted. 



Probably the most striking feature portrayed by this section is 

 the close proximit}^ with which the three classified types of water, 

 viz. Atlantic, Arctic, and Banks, abutted each other. No such ex-

treme liydrographical ranges or such abrupt transitions are found 

 at any other place in the world. An invasive body of warm salty 

 Atlantic water had worked shoreward in the submarine de])ression 

 which is charted on the eastern side of the Grand Bank in this 

 latitude.'^^ Banks water, which occupied all depths over the Grand 

 Bank, has been found to resist displacement and has often shown a 

 tendency to work eastward and northeastward, especially in the sur- 

 face layers.^2 ^^ It exhibited such a characteristic tendencv during
