a projected investigation on the psychological effect of food. He 

 thus saved much valuable time and was enabled to begin active 

 experimenting in the fall of 1913. 



Dr. Paul Roth, of Battle Creek, Michigan, has constructed a 

 respiration apparatus of the type developed in the Nutrition 

 Laboratory' and has been actively prosecuting researches on the 

 metabolism of normal women subsisting on a vegetarian diet. 

 During a visit to Battle Creek in January 1913, the Director per- 

 sonally supervised a number of experiments and assured himself of 

 the correctness of Dr. Roth's admirable technique. The investiga- 

 tion is still in progress. Dr. Roth also spent some time at the 

 laboratory acquiring the technique for operating the portable form 

 of the Haldane gas-analysis apparatus and the making of alveolar- 

 air determinations by the Haldane-Priestley method. 



Professor H. M. Smith, of the chemical department of Syracuse 

 University, kindly cooperated with us in an extensive series of experi- 

 ments with young men on the effect of an acidosis, normally induced, 

 carried out in the Nutrition Laboratory during the Christmas week 

 of 1912. Subsequently Professor Smith became permanently at- 

 tached to the laboratory staif . 



Dr. J. H. Means, of the Massachusetts General Hospital, spent 

 two months at the laboratory. During his stay he acquired the 

 technique for operating the portable form of the Haldane gas- 

 analysis apparatus and for making alveolar-air determinations by 

 the Haldane-Priestley method. He also devoted considerable time 

 to studying the construction and maintenance of the Benedict respi- 

 ration apparatus and participated in the carrying out of experiments 

 with it. 



STAFF NOTES. 



After a year of helpful assistance, particularly in the analysis of 

 the mineral constituents of the urine and feces of the subject of the 

 prolonged fast, Mr. Joseph Bock resigned to accept a position in the 

 department of chemistry in the Cornell University Medical School. 



Professor Raymond Dodge, of Wesleyan University, has been 

 added to the staff as experimental psychologist and placed in charge 

 of the laboratory for physiological psychology. Mr. E. H. Lange, 

 formerly electrician in the Western Electric Company, was added 

 to the laboratory staff as physicist. During the winter of 1912-13, 

 Dr. S. Morgulis was activelj^ engaged in experiments on animal 

 metabolism. 



In February 1913 the Director started on his third triennial tour 

 of European laboratories, scientific institutions, and hospitals, visit- 

 ing nearly all of the countries of Europe and paying special attention
