REPORT OF THE PRESIDENT, 1913. 23 



But science is cosmopolitan, and although many novel enter- 

 prises may be said to have originated with the Institution, it may 

 not lay claim to any monopoly in research; it can only contribute 

 here and there in a limited degree to the ever expanding aggregate 

 of verifiable knowledge. In recognition of these limitations the 

 Director has appropriately adopted the plan of inspecting, at fre- 

 quent intervals, the laboratories, the special apparatus, and the 

 technique developed elsewhere for the same and allied work. Thus 

 he has made during the past year a third triennial tour of Euro- 

 pean laboratories, hospitals, etc., devoted to such work. This has 

 afforded opportunity for numerous advantageous conferences with 

 colleagues and for the selection of new apparatus of proved utility; 

 while the Director has been able during the same time to give counsel 

 in respect to the adoption in other laboratories of apparatus and 

 methods similar to those of the Nutrition Laboratory. The latter, 

 therefore, like the Geophysical Laboratory, is no longer distinguished 

 by its singularity, but must now enter upon a career of friendly 

 rivalry with many cognate establishments. 



For details of the investigations of the year, reference must be 

 made to the Director's report. They are summarized by him under 

 thirteen principal heads, which range from studies of metabolism 

 in infants, through those of normal metabohsm in adults, up to 

 studies of chronic starvation and diabetes mellitus. Many pub- 

 lications issued or in press during the year are also reviewed by 

 the Director in his report. Considerable new apparatus has been 

 acquired and earlier forms of equipment have undergone modifi- 

 cations suggested by experience. Interesting mention is made of 

 visiting and cooperating investigators, of the special researches of the 

 laboratory staff, and of the conferences had by the Director during 

 his trip abroad. The staff has been enlarged during the year by the 

 addition of Professor Raymond Dodge, who will undertake work in 

 the psychology of nutrition, and by Mr. E. H. Lange, who will serve 

 as physicist for the staff. 



As already indicated in an earlier section of this report, one of 

 the noteworthy events of the year for this department will be the 

 J. completion of the second cruise of the non-magnetic 

 Terrestrial ship Camegie. She is now on the last stretch of this 

 Magnetism. ^y^[^q and may be expected to arrive at a home port 

 before the end of the calendar year, having been continually in serv- 

 ice since June 20, 1910. The aggregate distance traversed in her two 

 cruises will be in round numbers 100,000 miles. The corresponding
