Very nearly natural size. same illustration is seen the interior of the head of another example which allows of the removal of the brain from its proper cavity, thus facilitating its inspection from all sides. For the purpose of photographing the organ more distinctly, it has been placed in a right line above the head to which it belongs, and is.
