s, near Moosehead Lake. These men are called
jumpers, or jumping Frenchmen. Those subject to it start when any sudden
noise reaches the ears. It appears to be due to the fact that motor
impulse is excited by perceptions without the necessary concurrence of
the volition of the individual to cause the discharge, and are analogous
to epileptiform paroxysms due to reflex action.

The term spiritualism has come to signify more than has usually been
ascribed to it, for some recent authors are now using the term to denote
a neurosis or nervous affection peculiar to that class of people who
claim to be able to commune with the spirits of the dead.

Evidence obtained from clinical observations has tended of late to locate
the pathological lesions of chorea in the cerebral cortex.

Dr. Godlee's operation of removing a tumor from the brain marks an
important step in cerebral localization, and cerebral surgery bids fair
to take a prominent place in the treatment of mental diseases.

Wernicke has observed that the size of the occipital lobes is in
proportion to the size of the optic tracts, and that the occipital lobes
are the centers of vision.

Hughlings Jackson has observed that limited and general convulsions were
often produced by disease in the cortex of the so-called motor
convolutions. The sense of smell has been localized by Munk in the gyri
hippocampi, while the center of hearing has been demonstrated to be in
the temporal lobes. The center for the muscles of the face and tongue is
in the inferior part of the central convolution; that for the arm, in the
central part; that for the leg, in the superior part of the same
convolution; the center for the muscles and for general sensibility, in
the angular gyrus; and the center for the muscles of the trunk, in the
frontal lobes. In pure motor aphasia the lesion is in the posterior part
of the left third frontal convolution; in cases of pure sensory aphasia,
the lesion is in the left first temporal convolution.

The relation of the cerebrum to cutaneous diseases has been studied much
of late, and it is now held that the cutaneous eruptions are mainly due
to the degree of inhibiting effect exerted upon the vaso-motor center.

The relation of the spinal cord to skin eruptions has been more
thoroughly investigated and more abundant evidence supplied to
demonstrate the influence degeneration of the spinal cord has in causing
skin diseases, notably zoster, urticaria, and eczema.
