METABOLISM EXPERIMENTS NOS. 26 AND 28. 
Subject. — J. F. 8-, as in the previous experiment, weighing with 
underclothing about 61 kilograms (141 pounds). 
Occupation during > xpt riment. — Reading, writing, and miscellaneous 
observations within the apparatus, with as little muscular activity as 
practicable.
