REPORT OF THE PRESIDENT, IQII. 27 



Between fifty and sixty Research Associates have carried on investigations 

 under the auspices of the Institution during the year, either by aid of grants 



made directly to them or for the purpose of publishing re- 

 Investigations of gyj^g ^f ^hgjj. investigations. Several of these Associates 



have been connected with the departments of investigation. 

 Many collaborators have also participated in the researches carried on under 

 this head, and the fields of investigation are numerous and of very diverse 

 kinds. An idea of the extent and variety of this work can be best gained by 

 consulting the reports, in the current Year Book, of the individual investiga- 

 tors, by reference to the annual list of publications of the Institution, and the 

 general bibliography of the year. As indicating the diversity of these inves- 

 tigations, attention may be called to two remarkable publications in widely 

 different fields. One of these is a treatise on Dynamic Meteorology and 

 Hydrography, by Prof. V. Bjerknes, of the University of Christiania, and 

 marks a noteworthy advance in this difficult branch of mathematical physics. 

 Part I of this work has been issued and Part II is now in press. It is inter- 

 esting to note, also, that permission has been given to a foreign publishing 

 house to bring out an edition of this work in the German language. The 

 other work referred to is entitled "The Polynesian Wanderings," by Mr. 

 William Churchill. It attempts to trace the migrations of the Polynesians in 

 the Pacific Ocean by means of a critical examination of the philological con- 

 tents of their language. Mention may also be made in this connection of 

 progress in the publication of the Classics of International Law, one work of 

 which — namely, that of Richard Zouche — having been completed.
