PREFATORY NOTE 
In 1909 a number of friends of Professor Charles Otis Whitman 
planned a volume of the Journal of Morphology as an acknowl- 
edgment of the debt of American science to him as the founder 
and editor of the Journal. . 
A committee, consisting of Frank R. Lillie, Edwin G. Conklin 
and Thomas H. Morgan, was appointed to receive contributions 
of articles from his former students and his associates of the 
Marine Biological Laboratory. It was decided that the numbers 
for the year 1911 should constitute a ‘Whitman Volume.’ 
Professor Whitman died in 1910 before the first number was 
issued and the volume becomes a memorial to one who had a wide 
influence in the elevation of biological science. 
As Whitman’s ideals were broader than mere morphology, so 
the volume in the scope of its contents overlaps that field on all 
sides. 
The articles which were accepted by the committee were so 
numerous and extensive that not all of them could be published 
during the present year, although the volume is far larger than 
usual; consequently some of them will appear, with proper 
acknowledgment, in the next volume of theJournal of Morphology.
