抄録

Somatometrical results which were obtained on the Japanese monkey (Macaca fuscata) of deciduous tooth period were reported refering to the postnatal age and the dental formula.Though materials were obtained from monkeys which live in some different districts of western half of Japan and ages were estimated concerning almost half of them, all are combined for statistics and illustrations without considerations as to these matters, because not only the materials were limited to a small number but also in fact the group or troop differences seemed not to be distinct so far as considered and errors in estimations of age would be possibly within only plus and minus one month in almost all of estimated cases. The sexual differences were not conspicuous too, and, therefore, almost not considered in the present paper. As to some other explanatory notes and the results obtained, see tables and figures.
