Editor's Note.

This year, 1988, marks the Centennial of the Marine Biological Laboratory. In celebration of this anniversary, The Biological Bulletin has reprinted-with the permission of the University of Chicago Press-F. R. Lillie's (1944) book, The Woods Hole Marine Biological Laboratory as a supplement to this (February, 1988) issue. Not only is 1988 a year to celebrate the laboratory's accomplishments, but it is an appropriate time to recognize its journal, The Biological Bulletin. It is also an opportune time to make any changes in The Biological Bulletin that seem appropriate to the times and to reaffirm its editorial policy. Accordingly, the cover of The Biological Bulletin has been redesigned in keeping with modern trends and the page size has been increased from 5 inches to 7 inches. This permits two column printing for increased ease of reading. These changes in format may seem drastic to some. However, no significant changes in editorial policy are planned. The Biological Bulletin will remain a journal of general biology. Manuscripts from all fields of biology, be they animal or plant, aquatic or terrestrial, descriptive or experimental are considered for publication. This, then, will continue the editorial policy that has obtained throughout The Biological Bulletin's history. This very interesting history of The Biological Bulletin is reviewed by Ms. Clapp, Assistant Editor.
