Thresholds of salty taste among Japanese youth were examined by the previously described procedure of Point Scoring and Integration. (See, The Race Hygiene Vol. 16 (1949), No. 4, p. 11A). The threshold of judgment (Cj) and that of perception (Cp) are givon in concentrations of NaC1 solution in the following table: The range of individual difference may be perceived from the frequency distribution di: grams in Fig, 1. (p. 116) where the full line diagram corresponds to the threshold of perception and the dotted line one to that of judgment. The diagrams on the upper part of the figure are for boys and those on the lower part are for girls. At the uppermost of Fig. 1. dots and crosses serve to show threshold values for salty taste by previous authors, both domestic and foreign. Female persons appear to be inclined in general more sensitive than male persons, although there must be set a reserve considering the circumstances that the present survey mainly dealt with a special age class, viz. adolescence, in which the mental predisposition especially in boys may exert some influence on the result of threshold testing.
