24 KEPOUT OF THE COUNCIL. 



denser waters were driven up Channel and insliore, causing a rise of 

 salinity, the fall at the Oircrs and Koijal Sovereign being easily ex- 

 plained 1))' the fact that the Isle of Wight is always surrounded by 

 comparatively fresh water, and that a strong gale from the south-west 

 or west would drive this eastwards along the shore. 



The plankton observations show that a large proportion of the more 

 oceanic organisms found off the mouth of the Channel do not penetrate 

 for any considerable distance up Channel, even along a central axis, the 

 percentage of oceanic species having on each cruise fallen below forty 

 at the stations on the line from the Isle of Wight to Cape Bartieur. 

 When compared with those taken by other countries in the southern 

 part of the North Sea, the observations indicate that very similar con- 

 ditions exist in the eastern end of the English Channel (from the Isle 

 of Wight to the Straits of Dover) to those found in the southern part 

 of the North Sea, between a line from the Wash to Heligoland and the 

 Straits of Dover. 



The results both of the liydrographic and of the plankton work can 

 only be interpreted on the supposition that during the period under 

 investigation there was on the whole a constant passage of water from 

 the Channel into the southern part of the North Sea, but the rate at 

 which this passage of water took place must have been very slow.
