that of the waters east and north of it (Station 10318, surface density 

 1.0242); but the surface density off Cape Ann was even lower (Sta- 

 tion 1030G; density 1.0228). 



It is now possible, for the first time to compare the density of the 

 Gulf of Maine, and of the waters oft' southern Nova Scotia, with that

of 1914 and 1915); in the inner edge of the Gulf Stream (Station 10218); 



and in the mixed water over the continental slope (Stations 10220, 10295). 



over Georges Bank, in the inner edge of the Gulf Stream (Fig. 38), 

 and in the mixed water along the continental slope. Down to 150 

 meters or so density was about the same in the western part of the 

 Gulf as in the Gulf Stream water, except for the immediate surface of
