PLATE XXVI 



Galton's method of counting the Ridges in Loops. The number of ridges as determined 

 by him are given in the left-hand top corner of each print: see our pp. 201-202. 



A dabbed and a rolled print of the same linger to indicate how the former may lead one 

 to classify as a loop, what the latter shows to be really a whorl : see our p. 213.
