the smaller) ; when the greater intensity occurs on the right 

 side this result is final, but if on the left side, the excess of the 

 result over 100 is subtracted from 100. Indices larger than 

 100 accordingly indicate greater intensity on the right side, 

 while figures less than 100 show that the higher intensity is 

 on the left ; in either case the magnitude of bilateral difference 

 is reflected in the value of the index. 



Membral asymmetry, like the following measures of asym- 

 metry, are stated in percentages of total intensities. The 

 percentage statement is followed as an adjustment to the 

 widely different total intensities among genera. In table 9

Asymmetries in Pattern Intensity 

 (.See text for explanation) 



the membral asymmetries, calculated as described below, are 

 listed for right and left sides for both palm and sole. For 

 each of the configurational fields the pattern intensities of 

 right and left sides were compared. The differences between 

 right and left sides are set down as asymmetries, allotted 

 to the side bearing the excess. Totalled, the excess is calcu- 

 lated as the percentage of the total intensity of that side. 



Total asymmetry refers to collective asymmetry, irrespec- 

 tive of distribution on palm and sole and on right and left 

 sides. The figure is obtained by adding all the absolute dif- 

 ferences in pattern intensity of all members, then converting
