NATURE STUDY REVIEW 



[8:9— Dec, 1912 



most striking differences in her studies were, not so much the 

 differences in the interest of varied materials, as the differences 

 between the preferences of boys and girls in the same material. 

 The St. Nicholas results differ from hers in that respect, as the 

 following totals show : 



Percentage of all boys who wrote regarding plant material, 

 21.36 per cent; of girls, 20.18. 



Percentage of all boys who wrote regarding animal material, 

 62.16 per cent; of girls, 60.32. 



Percentage of all boys who wrote regarding physical material, 

 15.28 per cent; of girls, 17.46. 



Percentage of all boys who write regarding miscellany, 

 1.34 per cent ; of girls, 2.04. 



As far as there are differences they are rather surprising. 

 Boys write more often of plant materials than do girls and girls 

 more regarding physical phenomena than boys. 



The following totals show the classification of plant, animal 

 and physical material under several subdivisions. The per cents 

 given in each icase are the per cents of the total questions and 

 observations in each group — plant, animal, physical.
