questions to the most trivial matters of his habits and his whims and
fancies. Some of their questions he cannot answer; some he does not
choose to answer; some he is not yet ready to answer, and when he is

expected to return an answer, plucked, ripe or unripe, from his private
tree of knowledge. The brain-tappers are like the owner of the goose that
laid the golden eggs. They would have the embryos and germs of one's
thoughts out of the mental oviducts, and cannot wait for their
spontaneous evolution and extrusion.

The story I have promised is, on the whole, the most remarkable of a
series which I may have told in part at some previous date, but which, if
I have not told, may be worth recalling at a future time.

Some few of my readers may remember that in a former paper I suggested
the possibility of the existence of an idiotic area in the human mind,
corresponding to the blind spot in the human retina. I trust that I
shall not be thought to have let my wits go wandering in that region of
my own intellectual domain, when I relate a singular coincidence which
very lately occurred in my experience, and add a few remarks made by one
of our company on the delicate and difficult but fascinating subject
which it forces upon our attention. I will first copy the memorandum
made at the time:

P. M. to 7.30, with ________and ________ the two ladies of my
household, I told them of the case of 'trial by battel' offered by
