File:E&S 1911 C-S key I.png

This Key-figure represents a front view of the head and the greater portion of the neck. The lines 2–18 indicate the levels at which the principal sections were cut, while those on the opposite side, l-10, indicate the levels at which the principal sections were bisected. This was done to show the structures in the brain at an additional number of levels. In spacing the sec- tions before cutting an effort was made so to orient them with reference to " Reid's base line" that the upper surface of Section 10 would be in the plane indicated by this line. It should be recalled that Reid's base line is a line drawn backward from the lower margin of the orbit to the center of the external auditory meatus. It will be observed by glancing at Key-figure II that the upper surface of Section 10 is at this level. This line is nearly the same as the " hori- zontal line " of the German authors, which passes through the lower margin of the orbit and the upper margin of the external auditory meatus.
