connection with the Massachusetts General Hospital and the Boston 

 Lying-in Hospital. 



M. Lucien Bull, Sub-director of the Institut Marey, in Paris, was 

 commissioned by the Soci^t^ Scientifique d' Hygiene Alimentaire et 

 d' Alimentation Rationelle de I'Homme, of Paris, to spend several weeks 

 at the Nutrition Laboratory in the fall of 1913, in studying the design 

 of the respiration calorimeter. During his visit here, M. Bull gave 

 invaluable assistance by his suggestions as to the installation of the 

 photographic registration apparatus, optical instruments, and similar 

 apparatus, a subject in which he has specialized for many years. 



Dr. Carl Tigerstedt, of Helsingfors, spent a few months at the 

 Laboratory, familiarizing himself with respiration apparatus of various 

 forms here employed. 



Dr. Hans Murschhauser, of the Kinderklinik in Diisseldorf , was con- 

 nected with the Laboratory for six months as Research Associate of 

 the Carnegie Institution of Washington. During this time he studied 

 the various respiration apparatus and carried out an extensive research 

 on the metabolism incidental to the work of walking, using a professional 

 athlete as a subject. 



Professor Howard T. Karsner, of the Harvard Medical School, has 

 actively cooperated in studying the physiology and pathology of the 

 respiration of rabbits in an atmosphere containing a high percentage 

 of oxygen. 



Dr. F. E. Wells, of the McLean Hospital, cooperated in an investi- 

 gation upon the psychological effects of moderate doses of alcohol, his 

 unusual experience in the free association tests being of special benefit. 



Dr. J. L. Gamble studied for several months the technique of the 

 infant respiration apparatus, acquiring proficiency in its use. 



Dr. J. H. Means, of the Massachusetts General Hospital, has coop- 

 erated with Mr. H. L. Higgins, of the Laboratory staff, in a series of 

 observations on the effects of drugs upon the alveolar air and the 

 gaseous metabolism. 



Dr. H. W. Stevens, also of the Massachusetts General Hospital, 

 cooperated in a study of the insensible perspiration and muscular 

 activity of infants. 



STAFF NOTES. 



Professor Raymond Dodge was unable to secure longer leave of 

 absence from Wesleyan University and hence was obliged to terminate 

 his very interesting series of observations on the psj^chological effects 

 of moderate doses of alcohol. The year spent at the Nutrition Labora- 

 tory by Professor Dodge was characterized by great experimental 

 activity and a keen interest in all of the affairs of the Laboratory. 

 There was scarcely a department of the work which was not materially 

 assisted by his counsel and his unusual technical skill.
