1. Marked characteristics and local variations are observed between the toe prints of various Ainu tribes and those of the mixed Ainu in Hokkaido. (Tables 1 and 2)
2. The toe prints of the Ainu of the present list which differ only slightly from those of mixed ainu but which are extremely unlike those of pure Ainu can be considered in the category of mixed-bred Ainu. The reason is described in detail in the present paper. Because of this, apparently marked local differences observed in comparing the Ainu tribes are not necessarily significant.
3. The Tocachi Ainu tribe has steadily maintained its distinctive characteristics. From a physical stand point, most of the Ainu are mixed. The Hitaka tribe, and more especially Iburi tribe are intensively influenced in the direction of mixed breeding.
4. Marked differences among individual local tribes are chiefly attributable to the fact that physically mixed tribes have been involved in the pure Ainucategory. Chiefly the differences take their origin from mixed breedingwith Japanese.
