These statistics noted by the subject within the calorimeter are recorded in a diary, together 

 with any other information which he thinks may be of value in interpreting the results of the 

 experiment. 



The main facts in the diary of experiment No. 12 are shown in Table IV. 



Table V recapitulates the record of work done on the ergometer. It is much less than would 

 be required to propel a bicycle the number of miles indicated by the cyclometer.
