sinus_, which lies in the brain between its two hemispheres, and is
there in a tranquil state, no matter how disturbed the brain may be
on either side. While I was in conversation with this spirit, some
spirits introduced themselves towards the anterior part of the head
where he was, and pressed upon him; wherefore he retired to one side,
and gave place to them. The spirit strangers spoke with each other;
but neither the spirits about me, nor I myself, understood what they
