Methods have been presented for the determination of main-line index and transversality of the distal plantar ridges. For studying the collective main-line formula, a scheme of ‘modal types’ for the four main lines has been introduced. The computation of the summational main-line index has been made possible by devising a scheme of numerical values for the various terminations of main lines D and A. Cases where the main line D or A is abortive or non-existent should be eliminated from the assessment of main-line index. The degree of transversality should be determined from the percentage proportion of the mean main-line index with the maximum possible index.
