THE ORBITS In many American groups the orbits are notoriously variable, yet their mean dimensions and index are of value. The Eskimo orbits have long been known for their ample proportions. Their mean height and breadth are larger than those of any other known people and the excess is especially apparent when proportioned to stature. Taking the family as a whole, the mean height of the two orbits in males averages approximately 3.64 centimeters, the mean breadth 4.03 centimeters; while the males of 23 Algonquian tribes give for the same items 3.42 and 3.93, and those of 12 Siouan tribes 3.58 and 3.96 centimeters. The general averages for the female Eskimo approach for orbital height 3.52 centimeters, for breadth 3.89 centimeters, dimensions which also surpass those in the females of any other known human group. These large dimensions of the Eskimo orbit are, however, on closer examination into the matter, found not to be racial characters except in a secondary way. They are the direct consequence of the high and broad face. The correlation of the orbital height and breadth with the height and breadth of the face are shown by the following figures. These figures indicate also some additional details of interest. ESKIMO ORBITS: RIGHT AND LEFT MALES
