 parallel columns the heights of boys measured in Berlin by 

 Schadow, and of bo3^s measured in Cologne by Angerstein,

 of boys of both German and American parentage in this city-

The figures in the above table, representing the heights of 

 Berlin and Cologne boys, though apparently averages of a 

 number of observations, are really more of tlie nature of esti- 

 mates. This is evident from an examination of the original
