We observe that only three of these crania are brachycephalic, while the remaining five, and the mean of all, fall under the class of dolichocephalic crania, according to our classification. Mr. Gillman would call some of them Orthocephalic, and the mean of the eight crania giving a cephalic index of .786 and .802 as an index of height might properly be so classified. The same gentleman exhumed from an ancient mound on Chambers Island, Green Bay, Wisconsin, six crania, which as to type were equally divided into long and short skulls, while the mean cephalic index, .817, assigned them to the brachycephalic class. The long skulls were not far removed, however, from the dividing line between the classes (.80). The energetic and intelligent labors of Dr. R. J. Farquharson of the Davenport, Iowa, Academy of Sciences, has placed within our reach measurements upon twenty-five mound crania.[241] The following are the most important measurements in inches: Key: A. CRANIA. B. _Horizontal Circumference._ C. _Longitudinal Diameter._ D. _Transverse Diameter._ E. _Internal Capacity._ F. _Cephalic Index or Ratio of Diameter._ +-------------------------------------+-----+---+----+-----+----+ | A. | B. |C. | D. | E. | F. | +-------------------------------------+-----+---+----+-----+----+ |Mean of Nine Crania from Albany, Ill.|19.8 |6.8|5.1 |68. |.768| |Mean of Eleven from Rock River, Ill. |20.15|7.0|5.4 |74.48|.771| |Mean of Four from Henry County, Ill. |19.5 |7.0|5.2 |74.47|.743| |One from Davenport |19.5 |7.0|5.25|76.20|.752| +-------------------------------------+-----+---+----+-----+----+ This table introduces a new feature into the investigation in hand; the brachycephalic or the near approximation to the short skull is displaced by a mean cephalic index of .758, indicating the well-marked dolichocephalic type. The mean internal capacity 73.3 inches falls considerably below the mean of mound crania as measured by Squier and Davis, Wilson and others, from localities farther south.
