THIS MANUAL CONTAINS MANY OF THE FACTS COLLECTED DURING THE STUDY AND RESEARCH WHICH LED TO THE COMPILATION OF THE SYSTEM. ASPECTS OF CODING, TAKING, SEARCHING, AND FILING PALMPRINTS, ALONG WITH A UNIQUE METHOD OF CODING DELTAS AND LOOP CORE FORMATIONS, ARE DISCUSSED AND INDIVIDUALLY ILLUSTRATED. VARIOUS TABLES SHOWING THE DISPOSITION OF PATTERN TYPES ON THE PALMAR SURFACE, DELTA TYPES, LOOP CORE RIDGE VARIATIONS AND A CHART INDICATING THE MODE, PATTERN TYPE, AND PALMAR SECTION OF IDENTIFICATIONS ARE INCLUDED TO ASSIST IN THE FORMATION OF FILING SYSTEMS. ALL ESSENTIAL DATA ARE PROVIDED SO THAT POLICE IDENTIFICATION BUREAU PERSONNEL AND RESEARCHERS MAY IMPLEMENT THIS PRACTICAL AND RELIABLE SYSTEM OF PALMPRINTING.
