 to the order of birth of the children, in order to investigate if there is any 

 difference between the first-born children and later-born children. An 

 investigation of this subject, based upon material collected in Oakland,

 childi'en, beginning with the sixth year, being taller and heavier than 

 later-born children. The following table contains the results of this in- 

 vestigation, based on the Toronto material : — 



Differences between Average Statures of Boys and Statures of Children of 

 Various Orders of Birth, and their Mean Errors (mm.).
