Some Italian anthropologists use the terms _centripetal_ and _centrifugal_ in regard to races. A centripetal people is one whose customary movements are toward the person of the actor, not away from him. Dr. McGee was particularly interested in securing a group of Ainu, because they have the reputation of being distinctly centripetal, perhaps the most so of any people. We had hoped to find strong evidence of this character, but cannot claim to have been very successful. It is true that the salutations are of that kind: the hand-wavings and beard-strokings are not expansive, outward movements, but toward the person. The knife in cutting is frequently, perhaps generally, drawn toward the cutter. These were the only centripetal facts which we observed. The method of singing the _yukara_, as already described, is very peculiar; possibly it will come into this category. Landor, whom we rarely care to quote, says something in this direction, which may be sound: “More interesting to me than their physical characters, were their movements and attitudes, which I was able to study and note correctly without their observation. For instance, when Ainu try to move some heavy body they pull it toward them; thus, when they drag their dugouts and canoes on shore, and again when they launch them, they never push from them but pull toward them. If an Ainu has to break a stick planted in the ground he does it by pulling it; whereas a Japanese will push it. Again in pulling a rope the Ainu pull; the Japanese push, by placing the rope over one shoulder and walking in the direction wanted. In a crowd, where a Japanese would push his way through by extending his arms and thus separating people, the Ainu seizes a man on each side, pulling one to the right and the other to the left, till space for him to pass is made.” Now, if these are correct observations and we are inclined to accept them as such, they illustrate the centripetal nature of the Ainu and the centrifugal nature of the Japanese.
