12 CARNEGIE INSTITUTION OF WASHINGTON. 



demands for correct information with respect to ways, means, 

 methods, and results, there are now presented also, not infre- 

 quently, requests for investigations in cooperative enterprises for 

 which other organizations, or in some cases individuals, are willing to 

 supply the necessary funds. This is a manifestation which, while not 

 unanticipated, has developed somewhat earlier than expected. It 

 calls for considerate attention, since it is Hkely to grow with time in 

 proportion as the Institution demonstrates capacity for trustworthy 

 management of funds and for effective conduct of research. 



On the death of Dr. Fletcher, November 8, 1912, editorial super- 

 vision of the Index Medicus was placed in charge of Dr. Fielding H. 

 Garrison, who had long been associated as principal assistant with Dr. 

 Fletcher in the publication of this work. Continuity of plan and pur- 

 pose is thus assured in the perpetuation of this current bibliography, 

 while the responsible editorship falls to one whose qualifications for 

 the task have met the exacting standards of his eminent predecessors. 



In accordance with the authorization voted by the Board of 

 Trustees at its meeting of December 13, 1912, a department of human 

 embryology, under the direction of Professor Franklin P. Mall, with 

 a small staff of associates and collaborators, has been planned and is 

 already engaged in active research. In arranging for this depart- 

 ment the Institution is peculiarly fortunate not only in enlisting the 

 directorship of Professor Mall, but in starting from a foundation 

 furnished by his remarkable collection of human embryos. It will 

 be seen also that this enterprise is of far greater import than might at 

 first appear, for it has fundamental relations to the science of anthro- 

 pology as well as to those of anatomy, physiology, and pathology, 

 which latter, indeed, from some points of view, may not improperly 

 be regarded as branches of the former widely inclusive science. The 

 efforts of the Institution to enter the domain of anthropology, to 

 which reference is again made in a later section of this report, are 

 thus in part realized in a most effective way. 



Another noteworthy event of the year is the construction of two 

 new buildings, a heating and lighting plant, and an additional labo- 

 ratory, for the Department of Experimental Evolution, authorized 

 by the Board of Trustees at their last meeting. Plans in illustration 

 of these buildings, which are now nearing completion, will be found 

 in connection with the annual report of the department in the current 

 Year Book. Two of the many uses which this laboratory is designed 

 to serve in the immediate future are those of housing and further 

 experimentation upon the unique collection of pedigreed pigeons, 

 studied for many years by the late Professor C. 0. Whitman, whose
