Dactylography deals with what is of scientific interest and practical value in regard to the lineations in the skin on the fingers and toes or rather on the hands and feet of men monkeys and allied tribes which lineations form patterns of great variety and persistence. The Greeks used the term δάκτυλος του̑ ποδός (daktylos tou podos finger of the foot) for a toe; and the toes are of almost as much interest to the dactylographer as the fingers and present similar patterns for study.
