82 The Hydrography of the Faeroe- Shetland Channel 



Norwegian sea (c), rather than a mixture of it with water which had 

 come from the south through the Faeroe- Shetland Channel, as I supposed 

 at the time. Its southward movement would account for its appearance 

 at Station VIII. in the north-west of the North Sea, referred to ahove, 

 and for the southerly drift of the Jackal during the observations. 



The section for July, 1900 (Fig. 8), shows a state of affairs so 

 remarkable that if it were possible to doubt the accuracy of the

observations, one would be almost inclined to take refuge in doing so, 

 but the complete consistency of four sets of soundings makes the 

 supposition unreasonable. Salinity is at all depths remarkably high, 

 scarcely falling anywhere below 35 - 4. At a depth of 400 fathoms — i.e., 

 100 fathoms below the Wyville-Thomson ridge, is a maximum of 

 salinity of 35-6, in water having a temperature of melting ice. Above 

 this is a mass of water of salinity about 35 - 4, the minimum occurring 

 witli low temperature near the middle of the channel in about 

 250 fathoms. Above this, again, the saltest (35*6) and warmest water
