The result was 43 deg., which agrees fairly with 48 deg., the mean of the loops and the whorls. In the middle finger the frequency of the arches was only half the above amount and barely suffices for calculation. It gave the result of 38 deg., which also agrees fairly with 43 deg., the mean of the loops and the whorls for that finger.
