large group of individuals simultaneously. Thus far, the metabolism 

 of a group of normal persons has been determined under the following 

 conditions: Sitting quietly and reading; sitting quietly and singing; 

 sitting quietly and reading aloud; standing quietly, standing up, and 

 sitting down; dusting chairs. These investigations have been carried 

 out with the assistance of Miss Alice Johnson and Miss Hendry and Miss 

 Boles. We are also under obligations to the Domestic Science Depart- 

 ment of the Boston Young Women's Christian Association for two 

 series of experiments during the winter. The cooperation of Simmons 

 College has been actively resumed and the accumulation of data should 

 proceed rapidly. 



NORMAL METABOLISM OF WOMEN. 



The extended series of metabolism measurements made with humans 

 of all ages has provided data for individuals of both sexes between the 

 ages of 19 and 32 years, but measurements of metabolism of women 

 over 50 years of age have been lacking. During the past winter espe- 

 cial attention has therefore been given by Miss M. A. Corson to secur- 

 ing normal women subjects over 50 years of age and a large number of 

 such experiments have been successfully completed. A few experi- 

 ments have also been made with men over 50 years of age. Thus data 

 regarding the basal metabolism of normal individuals of both sexes for 

 an important period of life are now available. The metabolism of 

 women under 50 years of age has also been studied in a number of 

 experiments to supplement the material already accumulated. 



PUBLICATIONS. 

 The following publications have been issued during the year: 



(1) Some psycho-physiological processes as affected by alcohol. W. R. Miles. Proc. Nat. 



Acad. Sci., 2, 703 (1916). 



A preliminary communication giving briefly the results of a series of obser- 

 vations duplicating a series made with the same subject by Dodge and 

 Benedict (Carnegie Inst. Wash. Pub. No. 232, 1915). The detailed results of 

 this repetition series of experiments are now being prepared for publication.

ence to the gaseous exchange. T. M. Carpenter. Am. Joum. Physiol., 42,

A brief abstract of the results of the experimental studies on rectal feeding 

 with alcohol which were made in 1916.
