l chord of the operator and its nerves, and with no farther
portion of his nervous system. Later, it will be seen the
interpenetration can extend farther.

But before this happens, a new phenomenon manifests itself, not of a
sympathetic character. The operator contrives to wake the entranced
person to the knowledge that he possesses new faculties. _He develops in
him new organs of sensation_, or rather helps to hasten his recognition
of their possession.

It is to be observed, however, that many and many who can be thrown into
trance will not progress so far as to the present step. Others make a
tantalising half advance towards reaching it _thus_; and then stop. They
are asked, "Do you see any thing?" After some days at length, they
answer, "Yes"--"What?" "A light." "Where is the light?" Then they
intimate its place to be either before them, or at the crown of the
head, or behind one ear, or quite behind the head. And they describe the
colour of the light, which is commonly yellow. And each day it occupies
the same direction, and is seen equally when the room is light or dark.
Their eyes in the mean time are closed. And here, with many, the
phenomenon stops.

But, with others, it goes thus strangely farther. In this light they
begin to discern objects, or they see whatever is presented to them in
the direction in which the light lies, whether before the forehead or at
the crown of the head, or wherever it may be. Sometimes the range of
this new sense is very limited, and the object to be seen must be held
near to the new organ. Sometimes it must touch it; generally, however,
the sense commands what the eye would, if it were placed there.

One tries first to escape the improbability of an extempore organ of
sense being thus established, by supposing that the mind of the
entranced person has only penetrated a little deeper than before into
yours, and perceives what you see. But I had the following experiment
made, which excludes this solution of the phenomenon. The party standing
behind the entranced person, whose use it was to see with the back of
her head, held behind him a pack of cards, and then, drawing one of
them, presented it, without seeing it himself, to her new organ of
vision. She named the card justly each time the experiment was repeated.

The degree of light suiting this new vision varies in different cases:
sometimes bright daylight is best; generally they prefer a moderate
light. Some distinguish obj
