Subdivision by ridge tracing.—There are marked accumulations under the classification numbers, where are collected together the slips con- taining impressions all or nearly all of which are Whorls (including Composites), and subclassification here is needed. Kidge tracing has been explained. As specialised by the course of the lower limb of the ridge forming the left delta, a Whorl may be I or M or 0. The index and middle finger of the right hand being taken, the former may be I or M or 0, and the middle finger may also be I or M or 0, so the combinations of the two fingers taken together
