CURRENTS OF THE ATLANTIC 57 



Table Illustrating the Passage of Bottle-Drift from the European 

 and African Side of the North Atlantic to the West Indies 



There are here shown the places of recovery in the West Indies and on the 

 American mainland of bottles thrown over in most cases on the eastern side of the 

 North Atlantic between the south-west of Ireland and the Cape Verde Group and 

 transported across the ocean in the North Equatorial Current. 



(The materials are derived from the bottle-drift charts of the U.S. Hydro- 

 graphic Office for October to May 1900-8, from Dr. Schott's Die Flaschenposten der 

 Deutschen Seewarte, 1897, from Commander Becher's papers in the Nautical Magazine 

 for 1852, from Major Rennell's Investigation of the Currents of the Atlantic Ocean, 

 1832, etc. ; the two first named being the principal sources.)
