Rubner also determined approximately the surface exposed by 
his animals, in part by direct measurement and in part by calcu- 
lation, and computed the heat production per square meter of sur- 
face, with the following results:

He also cites * the results of experiments by Senator on the heat 
production of fasting dogs, and a respiration experiment by Reg- 
nault & Reiset, as follows:
