TWENTY-FOURTH REPORT. 



members were elected to the Board of Trustees in the class of 

 1925: Professor I. F. Lewis, of the University of Virginia; Dr. 

 R. S. Lillie, of the Nela Research Laboratories; Professor E. P. 

 Lyon, of the University of Minnesota, and Professor D. H. Ten- 

 nent, of Bryn Mawr College. 



As part of their report to the Carnegie Corporation the Execu- 

 tive Committee drafted a statement concerning the Organization 

 and Policies of the Marine Biological Laboratory. As this is the 

 first attempt at such a formulation, it is herewith printed (p. 304) 

 as part of the Director's report for the criticism of the members 

 of the Laboratory. It is not intended to constitute a set of regu- 

 lations. It is descriptive of the practices that have grown up in 

 the past thirty-four years and of the traditions that have been 

 established; thirty-four years hence such a statement may have 

 considerable interest, after those who were concerned in the early 

 history of the Laboratory shall have departed from this scene. 



There are appended as parts of this report: (i) A list of the 

 staff for 1921, (2) A list of investigators and students in attend- 

 ance in 1921, (3) A tabular view of attendance for the last five 

 years, (4) A list of the subscribing and cooperating institutions in 

 1921, (5) The Evening Lectures, (6) A statement concerning the 

 Organization and Policies of the Marine Biological Laboratory, 

 (7) A list of members of the Corporation.
