All the above data, which I could easily multiply, prove 

 beyond doubt that the »gulf-streamwater» proceeding from the east 

 of Africa towards the Azores and the European coast, expands 

 above the 40° N. so far to the west as to approaoh the Amer- 

 ican coast. From 40" N. it advances to the north, to Ice- 

 land and the Färöe Channel. It turns in September to the 

 north of Iceland. From the Färöe Channel it flows into the 

 North Sea and, as will be shown further on, towards Spitz- 

 bergen, 



In the following I will treat of some styli-plankton forms

 styliplankton also foUows the South Equatorial current to S. 

 America as well as into the Caribbean Sea, and the Antilles 

 and Florida currents towards the north.
