Matteucci, that is,
the skin removed, and the animal dissected so as to expose the lumbar
nerves. By a galvanic current, they caused this frog to move, apparently
to revive, on the girl's arm. The effect upon her may be imagined. The
ignorant child, terrified out of her senses, spoke of nothing else the
rest of the day, dreamed of dead frogs coming to life all night, and
began to talk eagerly about it again the first thing the next
morning.[18] From that time her attractive and repulsive powers
gradually declined.

In addition to the privilege of much accumulated learning, in addition
to the advantages of varied scientific research, we must have something
else, if we would advance yet farther in true knowledge. We must be
imbued with a simple, faithful spirit, not presuming, not preoccupied.
We must be willing to sit down at the feet of Truth, humble, patient,
docile, single-hearted. We must not be wise in our own conceit; else the
fool's chance is better than ours, to avoid error, and distinguish
truth.

M. Cohu, a medical man of Mortagne, writing, in March, 1846, in reply to
some inquiries of Dr. Tanchon, after stating that the phenomenon of the
chair, repeatedly observed by himself, had been witnessed also by more
than a thousand persons, adds,--"It matters not what name we may give to
this; the important point is, to verify the reality of a repulsive
agency, and of one that is distinctly marked; the effects it is
impossible to deny. We may assign to this agency what seat we please, in
the cerebellum, in the pelvis, or elsewhere; the _fact_ is material,
visible, incontestable. Here in the Province, Sir, we are not very
learned, but we are often very mistrustful. In the present case we have
examined, reexamined, taken every possible precaution against deception;
and the more we have seen, the deeper has been our conviction of the
reality of the phenomenon. Let the Academy decide as it will. _We have
seen_; it has not seen. We are, therefore, in a condition to decide
better than it can, I do not say what cause was operating, but what
effects presented themselves, under circumstances that remove even the
shadow of a doubt."[19]

M. Hebert, too, states a truth of great practical value, when he
remarks, that, in the examination of phenomena of so fugitive and
seemingly capricious a character, involving the element of vitality, and
the production of which at any given moment depends not upon us, we
"ought to accommodat
