2. Bernstein's calculations on the surface energy changes in 

 working muscle are criticized. A much simpler method of calcula- 

 tion is used with a result similar to Bernstein's, namely, the energy 

 expended by a working muscle is much greater than the probable 

 changes in surface energy can furnish, Of course, future investi- 

 gations may bring to light sources of surface energy within muscle 

 as yet unknown.
