to laboratory management, the purchase of new apparatus, discus- 

 sions with foreign scientists on the many problems now under 

 investigation at the laboratory, and particularly on the data obtained 

 in the experiments during prolonged inanition and on the proposed 

 investigation into the physiological and psychological effects of ethyl 

 alcohol upon the human body. 



In Paris numerous conferences with Professor Armand Gautier, 

 the president of the Societe Scientifique d'Hygiene Alimentaire, and 

 various members of the special commission having in charge the 

 construction of a new laboratory, led to the making of a formal series 

 of recommendations. As a result, Mr. Lucien Bull, of the Marey 

 Institute, was commissioned to visit the Nutrition Laboratory for 

 a period of several months in order to study the type of respira- 

 tion calorimeter here installed. A duplicate of one of the calorim- 

 eters is to be constructed in the new laboratory now being erected in 

 Paris. 



The investigation into infant metabolism, in conjunction with Dr. 

 Talbot, necessitated a visit to the clinic and metabolism laboratory 

 of Dr. Arthur Schlossmann, of Diisseldorf . The active investigators 

 in Heidelberg were met in numerous conferences and assistance 

 was rendered in planning for the construction, in the laboratory of 

 the Medical Klinik, of a respiration apparatus of the type developed 

 in the Nutrition Laboratory. To establish intimate relations with 

 many Italian physiologists and pathologists several weeks were spent 

 in Florence, Rome, and Naples. One of the most active laboratories 

 in Europe in metabolism investigations is that of Professor Franz 

 Tangl, in Budapest, and many discussions of experimental data and 

 suggestions as to apparatus resulted from the visit. 



In many ways Berlin, with its numerous physiological laboratories, 

 particularly those of Professor Max Rubner and Professor N. Zuntz, 

 is the center of German physiological research. The new medical 

 clinics, particularly that of Professor His, and the recent develop- 

 ment of electrical apparatus for studying the heart, offered excellent 

 facilities for securing the newest physiological apparatus for the 

 laboratory. 



The opportunity of meeting Professor M. Schaternikoff was well 

 worth the long trip to Moscow. Since the inception of the Nutrition 

 Laboratory, it has been the policy of its Director to keep in intimate 

 touch with Russian physiologists, and the visits to Moscow and St. 

 Petersburg are always profitable. LTnfortunately as yet there is 

 no adequate system of abstracts in English, French, or German to 

 cover the Russian periodicals. 



As a result of the stay in Helsingfors, Finland, Dr. Carl Tigerstedt 

 has been appointed as Research Associate of the Institution attached 

 to the Nutrition Laboratory for the year 1913-14. American physi-
