NUTRITION LABORATORY. 289 



Professor Walter R. Miles, of Wesleyan University, has been 

 appointed physiological psychologist and placed in charge of the 

 laboratory formerly used by Professor Dodge. 



Professor H. Monmouth Smith visited several cities in Europe in 

 behalf of the Laboratory for the purpose of purchasing and arranging 

 for the construction of apparatus, and for conference with various 

 scientists. After a few weeks in Hamburg, Bonn, Heidelberg, and 

 Berlin, it was necessary for him to terminate his trip on account of 

 the European war. 



Mr. H. L. Higgins was granted leave of absence for several months 

 in the summer to cooperate with the New York State Commission on 

 Ventilation. 



INVESTIGATIONS IN PROGRESS. 



Metabolism in diabetes mellitus. — In studying certain important 

 problems in diabetes mellitus, it has been extremely difficult to secure 

 cases of the type especially suitable for this kind of observation. Con- 

 sequently the accumulation of data has not been so rapid as in the 

 earlier series of experiments. The establishment of a special laboratory 

 in the New England Deaconess Hospital, equipped with a respiration 

 apparatus for such studies, and the personal active cooperation of 

 Dr. Joslin, will, it is hoped, enable greater progress to be made. 



Metabolism of infants and the new-born. — No single research has pro- 

 gressed with greater regularity and with less interruption than the 

 study of the gaseous metabolism of infants at the Massachusetts 

 General Hospital, which has been undertaken in cooperation with Dr. 

 Fritz B. Talbot. A considerable number of the results have recently 

 been reported in Publication No. 201 of the Carnegie Institution of 

 Washington. The successful prosecution of this work has warranted 

 its continuance and, indeed, the program has been elaborated during 

 the past year by including a special study of the gaseous metabolism 

 of the new-born, almost daily observations being made with infants 

 but a few hours old. These observations have been made possible by 

 the cooperation of the Boston Lying-in Hospital, and the collection of 

 data is rapidly proceeding. 



Metabolism incidental to walking. — Dr. Hans Murschhauser, during 

 his sojourn in the Nutrition Laboratory, as Research Associate of the 

 Carnegie Institution of Washington for the year 1913-1914, carried 

 out an extended research upon the metabolism incidental to walking, 

 employing the treadmill devised in this Laboratory and a special form 

 of unit respiration apparatus. Dr. Murschhauser made his observa- 

 tions upon the athlete used by Dr. Cathcart in his earlier research 

 on the metabolism during bicycle riding. The walking experiments 

 covered a period of several months and a large mass of data was accumu- 

 lated. ' The computations of these data are now being verified and the 

 report is being prepared for publication.
