The percentage increments in the metabolism due to the various 

 household activities studied are given in Table II. These are 

 arranged in the order of increment in energy requirement. 

 Although perhaps of minor practical importance, it is of physio- 

 logical interest to note the metabolism necessary for reading aloud. 

 In these experiments the students read in unison either from a 

 standard college text book or from the book of Psalms. Three ex- 

 periments wath twenty-three to twenty-five women, with a total of 

 eight periods, showed increases of 3, i, and 5 per cent., respectively,
