of the girls is not concluded at this age. This can be stated with defi- 

 nition, but how long it will last cannot be definitely stated. 



It is of great interest that we already at this early stage can record 

 a remarkable difference between the pupils of the public schools and 

 the higher schools. In the last mentioned ones the boys keep their lead 

 in height until the 12.0 years (a ivhole year longer than at the public 

 schools) "^. The laws of development of this material can be studied until 

 18 for girls and 20 for boys. After the girls have caught up to the boys 

 at 12.0, they keep the lead until a trifle after T.fV2. Tlien the boys again 

 grow the tallest — a relation wliich of course is not changed later.

Those who might wish to study the number valuations, eventually 

 for comparison with the material of other countries, are referred directly 

 to the tables. In this work quotations from literature will be restricted 

 to the least possible. The work is no general exposé of the relations of 



' I shall quote the following from a treatise by H. B r y n, "Selbu and Tydalen, 

 An anthropological investigation of men, women and children in two Norwegian 

 inland country districts" (Christiania, Dybwad, 1921 — received after the con- 

 clusion of this work): "It seems to be a general law that the greater the average 

 height of the population is, the later the girls get the lead. But it also lasts longer, 

 before the boys again overtake the girls as to height". 



The first part of the quoted sentence ("the later the girls get the lead") 

 agrees consequently with our material. As to the proof of the last part ("the 

 longer it lasts before the boys again overtake the girls as to height") we cannot 

 present any material for comparison, as the investigation of the public schools 

 only reaches to the year of 14. We can presume, though, that it does not corre- 

 spond, as the divergence of the curves of the boys and girls of the public schools 

 at 14 years is so great, that there is no possibility for any crossing of the curves, 

 before this takes place at the higher schools (a little after 14%).
