vigorously, and he hopes before another 

 year to make a favorable report on the re- 

 sults obtained. 



Harold Pender, Johns Hopkins Univer- 

 sity, Baltimore, Md. For experiments 

 on the magnetic effect of electrical con- 

 vection. $750. 



Abstract of Report. — The object of Dr. 

 Pender's grant was to perform in Paris, in 

 conjunction with Mons. B. Cremieu, experi- 

 ments on the mag-netic effect of electrical 

 convection and to confer with M. Poin- 

 care concerning the same. Dr. Pender 

 met with great success in clearing up a 

 controverted question as to the presence of 

 a magnetic field about a bare metallic sur- 

 face when charged and set in motion, which 

 field is in all probability due to what is 

 usually termed a convection current of 

 electricity. 



E. W. Wood, Johns Hopkins University, 

 Baltimore, Md. For research, chiefly on 

 the theory of light. $1,000. • 

 Abstract of Report. — Professor "Wood re- 

 ports that one half of the grant has been 

 expended for the salary of an assistant, 

 and that the balance he plans to expend 

 for apparatus. Through the aid given he 

 was able to accomplish much more experi- 

 mental work than he otherwise could have 

 done. During the year he obtained results 

 which were piiblished in seven papers, all 

 of which pertain to researches connected 

 with the theory of light. 



A considerable amount of work was also 

 done on an investigation on the dispersion 

 of sodium vapor; tliis has not yet been 

 published. 



PHYSIOLOGY. 



"W. 0. Atwater, Wesleyan University, 

 Middletown, Conn. For expeiiments in 

 nutrition. $5,000. 



Abstract of Keport. — The purpose of this 

 grant was to promote researches involving 

 the direct determination of the amount of 



oxygen consumed by man for sustaining the 

 bodily functions. The grant has been ex- 

 pended chiefly for the services of experts 

 and assistants, for devising and construct- 

 ing or purchasing apparatus, for develop- 

 ing methods for the determination of 

 oxygen and for efficiency tests and experi- 

 ments Avith men in the apparatus. 



Several tests of the efficiency of the ap- 

 paratus and method of manipulation were 

 made. The feasibility of the use of the 

 apparatus for the experiments with men 

 has also been tested by three experiments 

 with different subjects, with satisfactory 

 results. Attention is now being devoted to 

 alterations and improvements in the ap- 

 paratus and to modifications of methods; 

 efficiency tests and experiments with men 

 are also in progress. 

 Arthur Gamgee, Montreux, Switzerland. 



For preparing report on the physiology 



of nutrition. $6,500. 



Abstract of Report.— Dv. Gamgee began 

 and has carried on a study of the extensive 

 literature on this subject, which had to be 

 mastered for the purpose of the inquiry on 

 which he was engaged. He began by in- 

 specting European laboratories and by 

 visiting scientific men in Europe. He also 

 visited Professor Atwater, at Middletown, 

 Conn., and acquainted himself with the 

 work now in progress there. He also 

 visited other Americans. It is probable 

 that his complete report will be transmitted 

 in May, 1904. 



PSYCHOLOGY. 



G. Stanley Hall, Clark University, Wor- 

 cester, Mass. For certain investigations 

 on the anthropology of childhood. $2,000. 

 Abstract of Report.— The result of Dr. 

 Hall's work in connection with this grant 

 is best indicated by the titles of the papers 

 he has published, giving the results ob- 

 tained during the year. These are (1) Re- 

 action to light and darkness ; (2) children's 

 ideas of fire, heat, frost and cold; (3)
