THE DIRECTORS REPORT. I 9 



cooperative relations of research and instruction that have always 

 given our laboratory a special character ; that we should cultivate 

 the cooperation of institutions of learning -and of naturalists from 

 all parts of America, and that we should maintain our democratic 

 form of organization. In the membership of our corporation and 

 of our board of trustees we have a large proportion of the best 

 representatives of biological research. Their continued loyalty 

 to the organization and purposes of the Laboratory will inevitably 

 secure its success ; our organization and ideals must therefore be 

 such as to commend themselves to our large constituency. 



Trustees. During the past year the following new members 

 have been added to the board of trustees: Dr. Milton J. Green- 

 man, director of the Wistar Institute of Anatomy and Biology of 

 Philadelphia; Professor G. H. Parker, of Harvard University; 

 Professor Ross G. Harrison, of Yale University, and Professor 

 T. H. Montgomery, Jr., of the University of Pennsylvania. The 

 best thanks of the board of trustees is due these gentlemen for 

 their willingness to serve, and the Laboratory is to be congratu- 

 lated on the increase in prestige and usefulness assured by their 

 presence on the board. We have to record with profound regret 

 and sorrow the loss by death of the distinguished professor of 

 zoology of Johns Hopkins University, William Keith Brooks, 

 who has been a member of the board since 1893. 



Staff. At the close of the season of 1907 Professor Drew 

 resigned as head of the Department of Zoological Instruction 

 and his place was rilled most ably in 1908 by Professor W. C. 

 Curtis, of the University of Missouri, whose previous long con- 

 nection with the Laboratory fitted him unusually well to take 

 up this important work. Professor Drew took charge of the 

 instruction in embryology in 1908. Both of these gentlemen will 

 continue in charge of their departments. Professor Drew has 

 also acted as assistant director since last August at the request 

 of the director, and his formal appointment to this office is 

 recommended. Professor A. P. Mathews continued in charge of 

 physiology, and Dr. George T. Moore in charge of botany ; special 

 acknowledgments are due both for rendering their services with- 

 out compensation.
