2l8 REPORTS ON INVESTIGATIONS AND PROJECTS. 



Prof. H. M. Smith, of Syracuse University, has spent considerable time 

 in the Nutrition Laboratory, acquiring the technique of respiration experi- 

 ments, and as a result has instituted a series of observations in Syracuse 

 University on the metabolism of athletes, employing one of the respiration 

 apparatus belonging to this laboratory. The research is well under way and 

 promises interesting results. 



Prof. W. G. Anderson, of Yale University, was at the laboratory two 

 weeks acquiring the technique of gas-analysis with the Sonden and Haldane 

 gas-analysis apparatus. 



Dr. David L. Edsall, of the Washington University Medical School, re- 

 cently appointed Professor of Clinical Medicine at the Harvard Medical 

 School, spent a good part of the winter in the laboratory, studying with a 

 small respiration apparatus, paying particular attention to the effect of 

 altered respiration types upon the carbon-dioxide elimination. The graphic 

 records secured by Dr. Edsall and the amounts of carbon dioxide simultane- 

 ously measured have suggested many important problems in this field. Dr. 

 Edsall made this research the basis of his Shattuck lecture, "The clinical 

 study of respiration," delivered before the Massachusetts Medical Society, 

 June ii, 1912.* 



Dr. Paul Roth, of the Battle Creek Sanitarium, Battle Creek, Michigan, 

 has devoted several weeks to a study of the methods used in this laboratory 

 for determining the respiratory exchange, with a view to making important 

 investigations upon the metabolism of vegetarians. Dr. Roth's extraordi- 

 narily skillful technique and thorough understanding of problems of this 

 nature insure a most valuable study of the metabolism of those persistently 

 living upon a non-flesh diet. 



Prof. C. C. Benson, of the Department of Household Science, University 

 of Toronto, Toronto, Canada, spent the summer at the laboratory, thor- 

 oughly familiarizing herself, under the direction of Mr. Thorne M. Car- 

 penter, with the construction and technique of the respiration apparatus. 

 She conducted a large number of individual experiments, bearing in mind 

 particularly the problems in connection with her work on women at the 

 University of Toronto. A respiration apparatus of the latest type used in 

 this laboratory is soon to be constructed at the University of Toronto, and 

 the experimental work carried out with it promises to add materially to the 

 data regarding the metabolism of women. 



RESEARCH ASSOCIATE. 



The Executive Committee of the Carnegie Institution of Washington ap- 

 pointed Dr. E. P. Cathcart, Grieve Lecturer of Physiology in the University 

 of Glasgow, as Research Associate attached to the Nutrition Laboratory for 

 the academic year 1911-12. Dr. Cathcart's previous experience in meta-
