a light upon what we have mentioned before, that the boys at the higher 

 schools of all ages — therefore also before 13 — have a smaller weight- 

 height index than the girls. This then is not caused by one in proportion 

 to the public school large index for the girls of the higher school. On 

 the contrary, also the girls have a somewhat small index in proportion 

 to the public school, but the boys have a comparatively still smaller one. 

 Note. Our material gives no exact information as to the cause for 

 this smaller weight-height proportion for the pupils of the higher school -'^ 

 especially the bo3's. It is — after the opinion of the author — reasonable 

 to think of two things. Firstly it is well known, that children from the 

 socially better off classes grow quicker and puberty develops earlier. 

 When we suppose that an early developed boy of 10 in his total develop- 

 ment answers to the average type of 12, then it is likely that he also 

 can have reached year 12 in weight-height proportion, have an index 

 corresponding to the T2-average, hence smaller than the lo-average. 

 This, however, does not wholly explain the case: 10 year olds boys at 

 the higher schools have an average height of 136.6 cm., which for the 

 public school falls between 11 and 12 (nearer to 11). The index of the 

 higher school for 10 (1.18) is yet still smaller than that of the public
