(schools for the feeble-minded). The poorer the weight is at the school, 

 the higher will be the "proportionate number". 



The combination, about which we refer to the cartogram, fig. 12, 

 now gives us a very illustrative survey and — with one single exception 



— a most likely result, in other words, on the whole well consistent with 

 the experiences that had been gathered concerning the pupils relative to 

 the part of the city where they live. 



First it shall be mentioned that the schools for the feeble-minded 

 which — just because of their purely special material not marked down 



— are a good 'way behind the poorest public school, yes, separated from 

 it by a n'ide intermediate space, do not join in the continuous series, 

 which now begin for the 20 of the named 2^ schools. This series from 

 Rosenhof (2.08) to Majorstuen (1.98) are so evenly growing toward a 

 stronger weight, that any separateness would be artificial. But we see 

 distinctly how, within these even series, we find among the "poorest" 

 the three most northern schools, Rosenhof, Lilleborg, Bjölsen; then the 

 four east-side schools in a row, \'ahl, Töien. Kampen, \'aalerengen ; and 

 finally the most southern school in the city. Ruselokken. This is the 

 school we meant by the one single exception, as mentioned above. This 

 school had before been regarded as a "good" school, as it in a way be- 

 longs to the west-side of the city, and therefore could not lay claim to 

 very many of the places at the vacation colonies. But the school is 

 largely recruited from the harbour district Piperviken, where there for 

 one thing is very poor housing, so the statistical result is only what might 

 be expected. Further down the list we find the medium good weights 

 in what can, on the whole, be designated as the center of the city, plus 

 the old part of the town, Oslo. Finally the best weights are found at 

 the west-side schools, beginning with IIa and Majorstuen (both 1.98). 



Note. The classes for the hard of hearing at IIa are recruited from 

 the whole city and show a number of 2.01, corresponding to a more 

 medium development. 



From IIa and Majorstuen — the two first ones of the "best" schools 

 in the list — there is a considerable leap to the still better Uranienborg 

 (1.9 1) and from there again a leap to the best, Boltelokken (1.87) and 

 the schools for delinquents (1.86). This last is — to begin with — a 

 very sensational result: The bad, misbehaving children from the poor 

 homes stand as number i in weight! The explanation is, however, simple, 

 and at the same time very important. It proves to us on one side the 

 sit'ift reaction of the child organism from its surroundings (cf. page 12, 13,
