of upwards of 36%o; a fact worth noting, since this is the only time 

 the Grampus has encountered it on her recent cruises (1914a, 1915). 

 The saHnity profile running from Georges Bank, across the Eastern 

 Channel, toward Nova Scotia, shows that though the water was of 

 about the same temperature over Brown's, as on Georges Bank, it 

 was decidedly salter there (34%o)- But its most interesting feature,

and that of the succeeding profiles (Fig. 29-31), is that the low tem- 

 perature of the Nova Scotian coast water (p. 174) is accompanied, in 

 the upper layers, by correspondingly low salinity. Off Halifax (Fig. 

 31) the freshest water, like the lowest temperature, was localized close 

 to the land, with a considerable increase in salinity, passing offshore.
