5. Two vital strength-weight indices of equal number may 

 have different values, as exponents of physical efficiency, 



" dej^ending upon whether they are com})Osed of a vital index 

 and a strength-weight index of corresponding heights or of 

 a high and a low index. 



6. So far as can be judged from observation of about 100 

 cases, the vital strength-weight indices of women which corre- 

 spond to the highest efficiency of the most manifold adapta- 

 bility in the gymnasium are those composed of a strength- 

 weight index of 6.2 or more, and a vital index of 0.0550 to 

 0.0600 or somewhat above 0.0600. Those composed of a low 

 strength-weight index and a vital index considerably higher 

 than 0.0600 (0.0650 or more) are more difficult to estimate, 

 and their number is comparatively small. 



As an illustration of the correlation between the growth 

 of the vital strength-weight index and the growth of working 

 capacity in the gymnasium the following table is offered. It 

 will be understood without further explanation than to say 

 that the marks are our subjective estimate of the capacity of 

 the students to climb the perpendicular rope. The figures 

 indicate the number of students who have the index as given 

 at the top of the perpendicular column, and the mark in 

 climbing as given at the head of the horizontal column. A^ 

 means excellence ; C, entire inability ; B^ the first struggling 

 success to climb a few inches upward ; the other marks 

 indicate the intermediate stages of proficiency.
