. Biology of the vertebrates : a comparative study of man and his animal allies. Vertebrates; Vertebrates -- Anatomy; Anatomy, Comparative. m, COMPOSITE I â LOOP ARCH Fig. 207. Diagrams of the four main types of finger patterns. The whorl and the composite have two deltas (A's); the loop, one, and the arch, none, The loop may be a radial loop, or an ulnar loop according to whether it opens outward toward the thumb (radial), or toward the little finger (ulnar.) (After Wilder and Wentworth.) The patterns may be roughly classified in general types, namely, whorls, loops, composites, and arches, as indicated in Figure 207. Loops may be ulnar or radial according to whether they stream outward toward the ulnar (little finger) or the radial (thumb) side, while arches may be simple, as in the figure, or if more pronounced, tented arches. Combinations of these types upon the fingers of both hands taken together, and the infinite variety in the minutiae that each type reveals upon careful scrutiny, make possible an almost unlimited subdivision and classification. Thus, it has come about that finger-print codes have been worked out, which may even be tele- graphed or radioed from one part of the world to another in the interests of personal identification. By reason of the fact that finger prints are easily made and kept on file, they may be utilized conveniently in a great variety of ways. Upon a bank cheque, passport, or non-transferrable documents of any kind, for example, such a personal imprint furnishes a unique signature which cannot be forged. In the case of soldiers, sailors, the personnel of large industrial plants, voters, babies at maternity hospitals, inmates of institutions, crim- inals, undesirable immigrants once rejected, dead bodies recovered from disastrous catastrophes or accidents, aphasia victims, and in many other.
