The data used in compiling the tables were the prints of 1,500 

 different digits, namely, the thumb, forefinger and middle fingers of 

 the right and left hands of 250 students. The relative frequency of 

 arch, loop and whorl in the 1,500 digits was a follows : 



TABLE I. 



1,500 DIGITS OF 250 STUDENTS. 



162 arches, i.e. . 1Q-8 per cent. 



911 loops 60-73 



427 whorls . 28'46 



Compare this with Galton's table, in which he records observa- 

 tions of 5,000 digits of 500 persons. His results are : 



Arches 6-5 per cent 



Loops - ' - 67 



Whorls - ... - 26 



The difference here is probably due to the fact that in the latter 

 table the ring finger and little finger are recorded as well as the other 

 three. 



On the little finger loops predominate, and hence Galton's higher 

 percentage of loops and consequent lowering of the other two per- 

 centages. 



The second table is intended to show the peculiarities of the 

 different digits as regards the patterns found on them.
