It will be observed that in both of these experiments the 
_ outgo of energy, z. ¢., the heat given off from the body and 
fe the heat equivalent of the external muscular work done, as 
_ measured by the respiration calorimeter, is less than the income 
- or estimated heat of combustion of food and body material
