The first directory for any extensive political area was on the marine laboratories of Europe, 

 and was published in 1893 by Bashford Dean (Am. Nat., 27:625-37, 697-707). Since that 

 time, several accounts have been written covering stations in particular countries or on a 

 world-wide basis. The more important of these accounts, which now serve as historical mile- 

 stones, have been summarized by H. A. Jack in his "Biological Field Stations of the World" 

 (Chron. Botan., 9:1-73, 1945). Since Jack's directory was issued, the most comprehensive ac- 

 counts of marine biological and fisheries centers have been issued by FAO. To date, the 

 following have been published: "Fishery Research and Educational Institutions in North and 

 South America," 1950; "Directory of Fisheries Institutions, Europe," 1955 (revised 1957) 

 and "Directory of Fisheries Institutions, Asia and Far East," 1957. 



In 1953, the writer compiled a Directory of Hydrobiological Laboratories and Personnel in 

 North America (University of Hawaii Press) which listed 187 marine and fresh-water sta- 

 tions. The present Directory revises and brings up-to-date the stations of this geographic area. 



Especially helpful for the present compilation have been the numerous reports of European 

 marine and fresh-water biological laboratories issued by the United States Office of Naval Re- 

 search, London Office, in their publications, "European Scientific Notes" and "Technical 

 Reports, ONRL." Lastly, the writer has made extensive use of his personal knowledge of 

 marine and fresh-water biological laboratories secured during visits to such institutions in many 

 parts of the world.
