COWALITSK.
This extraordinary relic was also brought from the Columbia river by my
friend Mr. Townsend. Deformed as the other skulls of this series are, this one
surpasses them all in those factitious proportions which result from mechanical
pressure to the forehead. Thus the vertical diameter is reduced to little more
than four inches—the top of the cranium presents a flattened arch not far
removed from a horizontal plane, and the face is protruded until the facial angle
is reduced to sixty-six degrees, the lowest grade which I have observed in any
human skull. I have represented both profile and vertical views of this head;
but the latter represents it as possessed of too much regularity, especially about
the zygomae. The first or profile drawing is perfectly accurate in all its proportions,
but the artist has inadvertently drawn it one sixth of an inch too small in
each of its diapieters.
