1923. No. 4. PHYSICAL DEVELOPMENT OF CHILDREN AND YOUNG PEOPLE. 23 



On table 6 a is seen a comparison in weight between i) Frogner 

 and \'estheim higher schools, 2) Borgerskolen and Hammersborg, 3) all 

 the public schools, and 4) the schools for the feeble-minded. This applies 

 to the age 10 to 14 years ^^. 



In order to investigate whether the difference of weight or the 

 difference of height is the most obvious by a comparison between the 

 public school and the higher school, it would be most practical to see 

 the numbers of the public school material in percentage of the numbers 

 of the higher school material. For the purpose of getting a large material, 

 the collected material from the two school systems are here compared for 

 the years 9 to 14. Table 7 answers this question regarding the absolute 

 numbers of weight and height. 



The following is deducible from table 7 concerning the difference 

 betzi'een the public school and the higher scliool: — 



The difference of weight is more than tivice as large as the dif- 

 ference of height. The boys of the tzco school systems differ more 

 strongly, both in height and weight, than the girls do. A comparison 

 between the year classes 9 to 14 displays the greatest differences in the 

 younger year classes.

Except for Borgerskolen and Hanimersborg, where we only have the ages 13. and 14 

 (just as for table 6 b — girls"). The tables demonstrate the diminishing values from 

 the first mentioned schools to the last mentioned ones.
