We have already called attention to the extensive and thorough work performed by Professor Joseph Jones in Tennessee, the report of which was published in 1876 by the Smithsonian Institution in a “contribution” entitled _Explorations of the Aboriginal Remains of Tennessee_. Professor Jones secured above a hundred mound and stone grave crania, mostly in the valley of the Cumberland and on the banks of the Big Harpeth River. Some of the skeletons accompanying these crania were of gigantic stature, a fact which is at variance with the opinion that they were related to the diminutive race of Inca Peruvians.[243] On the contrary, however, a strong argument for the relationship between the Mound-builders and the Peruvians is found in the frequent occurrence of the Inca-bone (_os inca_) so-called, on the mound crania.[244] Mr. Henry Gillman found this same bone in one of the crania exhumed by him from the great mound of Rouge River, Michigan, with a disposition to its formation in several others.[245] Professor Jones is convinced of the unity of the mound race throughout the entire Mississippi Basin. The following table of measurements, published in the _Antiquities of Tennessee_, is one of the most valuable which has yet been prepared: Key: A. _Number of Cranium._ B. _Facial Angle in Degrees._ C. _Internal Capacity in Cubic Inches._ D. _Longitudinal Diameter in Inches._ E. _Parietal Diameter._ F. _Frontal Diameter._ G. _Vertical Diameter._ H. _Inter-Mastoid Arch._ I. _Inter-Mastoid Line._ J. _Occipito-Frontal Arch._ K. _Horizontal Periphery._ L. _Diameter of Head and Face._ M. _Zygomatic Diameter._
