appear as two branches, one a little to the west of mid-channel, and 

 another on the east side, close to the land. la the interval between 

 May 24 and July 10 the distribution in the depth seems to have 

 become more uniform. In the depth the centre of low temperature 

 and salinity on the east side has disappeared, and apparently the whole 

 breadth of the channel is occupied by water of about 35"4 salinity. In 

 the upper layers the two branches of warm salt water are farther apart

at the surface, the western member is more strongly marked, while at 

 intermediate depths (100 to 300 fathoms) salinity has increased slightly 

 on the east side, and diminished on the west. The differences point 

 in effect to a strengthening of both the northward and southward 

 moving streams above 300 fathoms, the latter keeping to the west, 

 while the former keeps to the east, but sends a narrow branch, 50 to 

 60 fathoms deep, along the western side. It is noteworthy that there 

 is no indication of a southward movement of fresher water towards 

 the Shetlands.
