Contrasted with the long bones of miscellaneous North American tribes taken together, the Yukon Indian bones show absolutely slightly shorter humerus (or arm), somewhat shorter radius (or forearm), a slightly shorter femur (or upper part of the leg), and a plainly shorter tibia. These Indians had therefore relatively somewhat shorter forearm and especially the leg below the knees than their continental cousins. These facts are plainly evident from the radio-humeral and tibio-femoral indices of the two groups. In this relative shortness of the distal parts of the limbs the Yukon Indian approaches the Eskimo, standing near midway between the Indian in general and the Eskimo. There might be a ready temptation to attribute this to a mixture with the Eskimo; but an examination of the records will show that the same condition, so far at least as the upper limb is concerned (lower?), is already present in the old Bonasila skeleton, which gives no suggestion of an Eskimo mixture. It is more likely, therefore, that these are generalized characteristics of functional origin such as a considerable use of the small canoes. This view seems to be supported by the relative strength of the bones. In the Yukon Indian the humerus is stouter, the femur of the same strength, and the tibia very perceptibly weaker than they are in Indians in general. In the Eskimo, with even greater dependence on the canoe, both the humerus and the femur are notably stouter, while the tibia is weaker, than are similar bones in the Indians in general. The humero-femoral index in the Yukon Indians is unusually high, indicating a relative shortness of the femur. This character is not present in the Eskimo, nor in the continental Indian. It is probably also of old functional origin, though, this for the present must remain a mere suggestion. All of this shows clearly the interest and value of other skeletal parts than the skull, and particularly of the long bones, for anthropological studies. SKELETAL REMAINS FROM THE BANK AT BONASILA The skeletal material from the bank at Bonasila consists now of portions of three adult skulls, one male and two females, and of 13 bones of the male skeleton. All the specimens are more or less stained by manganese and iron and all are distinctly heavier than normal, showing some grade of fossilization. They closely resemble in all these respects the numerous animal bones from the bank and in all differ from the later surface burials of the place. THE CRANIA The male skull, No. 332513, is represented by the frontal bone united with a larger part of the face, a separated left temporal, and the right half of the lower jaw. A large Inca bone, recovered from the beach a year later, may also belong to the same specimen. The missing parts are probably still somewhere in the sands of the beach where there is going on a very instructive scattering and redeposition on a 4 to 6 feet lower level of the contents of the old bank.
