in such only, the ridge count may be taken, and by it the patternsmay be conveniently subdivided; but here the customary count is notthat between either delta and the core, but between the right point of deltaand the line traced from the one on the left. The cross line, upon which thecount is taken, should be drawn perpendicular to the ridges to be counted,or as nearly so as the print permits. Thus, Figure e of Plate III is an DESCRIPTION OF PLATE III a. Inside Spiral Whorl, 3 intervening ridges. Code word, WABBLE.h. Inside Whorl, intervening ridges three or more, but cannot be counted owingto the absence of right delta. Code word, WARP. c. Meeting Whorl, no intervening ridges, many would class this as an elongatedwhorl, with code word WRAITH. Code word, WEAK. d. Meeting Whorl, 1 intervening ridge inside. Code word, WEB. e.

Code word, WHARF (o) 206 Personal Identification Outside Whorl with a ridge count of 8; and/ of the same plate is Outsidewith a ridge count of 5. Since ridge counts of 1 and 2, both inside andoutside, are classed with Meeting Whorls, the count for the I and O groupsbegins at 3, with nothing below. In tracing the lines from the deltas, the following rules should beemployed: Start at the left point of delta, tracing toward the right point of delta. When theridge ends, drop to the one underneath, or, when the ridge bifurcates, follow the lowermember of the bifurcation, (c); then If the ridge traced passes inside the right point ofdelta, with three (3) or more ridges intervening,the pattern is classed as an Inside Whorl.
