Ridge Counting.—As about two impressionsout of every three are Loops, the subdivision intoulnar and radial fails to split them up intogroups sufficiently small, and it is necessary there-fore to still further differentiate them by othermethods. Fig. 37 represents the ridges of an ordinaryLoop. The line S B joins the two terminal points, inner and outer terminus. If the ridges whichcut the line S B are counted they will be foundto number 17, so this Loop is specialised as a Loopwith 17 ridges or counts, and if it is the impressionof a right hand digit it would be further specialisedas an ulnar ; if of a left hand digit as a radic
