These three equations, which are deduced from 

 the general formulas, are intended to express the 

 principal data upon which the theory of walking 

 is based. If n = r =. 1, and 6=0, and we 

 substitute for ft. its Value as deduced from experi- 

 ment in walking, and let ((U -[- 1 ) g = 34.65,* 

 T = 0".7 and / = 0.95 met. by substituting these
