The experimental conditions were next complicated by the introduction
of abnormal positions of the eyes, head and whole body. The results of
tipping the chin sharply upward or downward and keeping it so fixed
during the process of location are given in the following table, which
is complete for only three observers:

The results of rotating the whole body backward through forty-five and
ninety degrees are given in the following table:
