 would be more in harmony with reality to unite in a curve the extreme 

 points of voyages starting from a limited district, in order to obtain in 

 the form of a plane a comprehensive expression of the mobility of the 

 Mongoloid race. In the passages from Japan it is directly obvious 

 with what remarkably mobile people we are dealing; this is a fact
