Abstract
1. The author has worked-out a new system of finger-prints analysis through bringing together the types of pattern of the various fingers to a total qualitative value of the following 5 types: A-pattern 2.3%, AL-pattern 3.5%, L-pattern 61.8%, LW-pattern 21.4%, W-pattern 11.0%. 2. Calculations of frequency have shown that sex difference does not exist with respect to the various types of total qualitative value. 3. Mother/child calculations of correlation in tetrachoric tables have given the following results: a) L/W: χ 2 = 34.38; r = 0.46 ± 0.06; b) A, AL, L/LW, W: χ 2 = 27.38; r = 0.31 ± 0.05; c) L/LW: χ 2 = 3.75; r = 0.13 ± 0.07.
