1 Owing to defects in the apparatus, the subject rode intermittently preceding the period here given. Of 
the 48 minutes so used he sat still for the last 20 minutes. The total time during which the subject 
actually rode was about 55 minutes, the heat equivalent of the work done being 120 calories.
