 the continental slope than an;y^fhere on the shelf. The ocean water 

 in the eastern side of the Gulf appears as a tongue of 33%o+ extending 

 northwestward from the Eastern Channel and Brown's Bank nearly

 fresh tongue, so evident on the surface over nearly the whole length 

 of Georges Bank (p. 182, Fig. 18), reappears only at the northeastern 

 end of the Bank (Station 10226) at this level. And water salter than 

 33%o, which hardly encroaches at all on Georges Bank at its eastern 

 end, covers almost half its breadth, at its western.
