NUTRITION LABORATORY. 187 



E. W. Brown, of the United States Navy, spent some weeks at the laboratory 

 during the summer, investigating methods of gas analysis and discussing the 

 question of the regeneration of air. He also carefully inspected the numer- 

 ous forms of apparatus in the laboratory in which closed volumes of air are 

 used for respiration purposes. 



Prof. H. Monmouth Smith, of Syracuse University, spent several weeks 

 at the laboratory acquiring the technique of respiration experiments with a 

 view to prosecuting researches on athletes at Syracuse University. 



STAFF NOTES. 



The importance of the researches on blood, gas analysis, and respiration 

 carried out at the University of Oxford by Dr. J. S. Haldane, and at the 

 University of Cambridge by Dr. Joseph Barcroft, warranted arrangements 

 for study at both of these universities by Mr. H. L. Higgins, of the Labora- 

 tory staff. Not only these two investigators, but also Drs. Bohr, Henriques, 

 Krogh, and Hasselbalch, in Copenhagen, accorded Mr. Higgins every oppor- 

 tunity for becoming thoroughly familiar with the methods and technique 

 which have been particularly well developed in these places. Mr. Higgins 

 secured much valuable apparatus and was able to materially augment our 

 valuable collection of reprints by separates of publications which were kindly 

 given him by the various investigators that he came in contact with. 



Later in the winter, Mr. T. M, Carpenter, of the Laboratory staff, made an 

 extended tour of Europe, visiting particularly the northern countries and 

 becoming more familiar with certain laboratories and researches which were 

 not included in a trip taken by him three years ago. It is of special interest 

 to note that this was highly appreciated by foreign investigators, who have 

 freely written of their pleasure in being given the opportunity to become 

 familiar with Mr. Carpenter's technique in calorimetric researches. 



INVESTIGATIONS NOW IN PROGRESS. 



METABOUSM OF NORMAL WOMEN. 



With the accumulation of material in regard to pathological cases, it is 

 obvious that the results for normal individuals are as yet too few to permit 

 the most detailed and satisfactory comparison; consequently, it has been the 

 policy of the Laboratory to secure as many observations on different normal 

 individuals as possible. Fortunately, through the interest of Prof. Alice F. 

 Blood, of Simmons College, we were enabled to study the normal metabolism 

 of young, healthy, normal women, who volunteered as subjects for respira- 

 tion calorimeter experiments. The results are of great value and will be a 

 positive contribution to our knowledge of the metabolism of healthy young 

 women, supplementing in an admirable way the researches instituted a year 

 ago, in which many of the women members of the Laboratory staff volun- 

 teered as subjects. Mr. L. E. Emmes is continuing these studies as oppor- 

 tunity offers.
