An eventual plumpness may furthermore be united with a healthy, ves 

 blooming appearance. — or it may be wholly pathological. These are 

 examples of, how utterly careful one must be in the use and judgment 

 of numbers concerning individuals. What follows relates only to charac- 

 terization of great masses. Table 14 gives information of the results 

 found. An index can help considerably for the comparison of an indi- 

 vidual from time to time, but it is also here the case, that the expert 

 subjective judgment is very far from superfluous. 



The curve fig. 14 a shows the average index for the public school 

 material: For the boys a steady decease from 7 to 14 years, somewhat

 — somewhat less steeply after 9 — 10 — loitil u.o, zchen the zceight- 

 height proportion begitis to increase. We see that as long as the index 

 decreases for both sexes, that is uiiiil 12.0, the boys are all the time 

 the heaviest for the height. 



The higher school (fig. 14 b) shozi' in the last mentioned respect 

 the very remarkable difference, that the girls in each and all ages have 

 an obviously higher index than the boys. The increase begins for the 

 girls at I J, for the boys at ca. iß. The whole development has for the 

 girls a more intense impress, decrease as zcell as increase go on after 

 steep lines; zcith the boys the deviation from the horizontale line i^ much 

 less emphatic. When we now look at the two curves, fig. 15, we see that 

 the boys as well as the girls have a smaller zveight-height proportion at 

 the higher schools than at the public schools, but the difference is (except 

 for the age Jj and 14) considerably larger for the boys part. This throws
