V. THE DIRECTOR'S REPORT. 



To THE TRUSTEES OF THE MARINE BIOLOGICAL LABORATORY: 



Gentlemen: I have the honor to transmit herewith a report 

 of the twenty-fifth session of the Marine Biological Laboratory. 

 The attendance of investigators at the Laboratory in 1912 

 exceeded that of previous years by a considerable number, 93 

 in 1912 as compared with 82 in 1911, and 62 in 1910. The 

 number of students in the courses was 67 as compared with 65 

 in 1911 and 64 in 1910. The total attendance was 160 in 1912, 

 147 in 1911, and 126 in 1910. During part of the season the 

 buildings were uncomfortably crowded; indeed if it had not 

 been for the additional space furnished by the Kidder annex 

 it would have been necessary to turn away a number of 

 investigators. The student accommodations are at present 

 ample and likely to remain so, but the limitation of space 

 assignable to individual investigators, especially in the gen- 

 eral research laboratories, is a serious handicap to the best 

 kind of work. For the season of 1913 some additional space 

 will be available, if needed, in the Yacht Club building; but the 

 facilities in this building and in the Kidder annex will be at best 

 makeshifts. 



Fortunately, such conditions will not long continue, as the 

 plans for the new laboratory building are now complete, and the 

 building will be erected in the coming summer. 



The number of subscribing institutions again showed an in- 

 crease, from 25 in 1911 to 29 in 1912. In 1907 the number 

 was 1 6 and the increase since has been steady. The follow- 

 ing subscriptions were new: Carleton College, Else Seringhaus 

 Scholarship of Normal College, Laboratory of Comparative 

 Anatomy of Harvard Medical School, University of Texas, 

 and Wabash College. It is gratifying to see this growing 

 recognition by institutions of the value of the facilities offered 

 by the Laboratory; but we must not cease to labor for its ex-
