THE REPORT OF THE DIRECTOR. 2Q 



funds. There were few demands for apparatus in the season of 

 1925 that could not be satisfied with that on hand; the machine 

 shop operated in cooperation with the department of scientific 

 apparatus in adapting instruments and making new ones. All 

 appliances are fully catalogued and cross-referenced as to distri- 

 bution in the various buildings and rooms and temporary loans. 



The equipment of the machine shop was completed during the 

 summer. This equipment is largely for metal work. It is 

 proposed to install a bench and equipment with a trained operator 

 for glass blowing which will permit some construction of glass 

 apparatus and all necessary repairs. It is not intended to 

 centralize all glass blowing here, but to provide for the more 

 delicate and complicated pieces of work. 



5. Attendance. Reference is made to the list of Students and 

 Investigators in attendance (pp. 43-51) and to the Tabular 

 View of Attendance (p. 51). The number of students admitted 

 was held to the usual quota, which necessitated refusing a con- 

 siderable number of applicants; the laboratories in the old 

 buildings were used for the work of the classes as before. The 

 number of investigators was 208 which is 14 more than the 

 previous year the largest attendance heretofore. This season the 

 space was ample. The policy in assigning space was determined 

 partly by the rates, but, for the rest, the better equipped and more 

 commodious quarters of the New Building and the Crane 

 Building were filled first both for the beginning investigators and 

 the older ones. All of the space in the brick buildings was thus 

 occupied, and it was remarkable how little unoccupied space was 

 left even in the old buildings after the need for crowding ceased 

 and each investigator was given ample quarters. The number 

 of institutions represented by students was 65, by investigators 

 74, combined 112 with allowance for duplications. 



The following foreign countries and institutions were repre- 

 sented: Brazil, H. Paul's Medical School; China, Peking Uni- 

 versity and Shanghai; Czecho-Slovakia, Charles University 

 Prag; England, University College, London; Germany, Kaiser 

 Wilhelm Institut Fur Biologic; Holland, University of Leyden
