al, yet the thread of continuous recollection which
connects the present moment with its predecessors--consciousness and
memory--has evidently been snapped at some point of time prior to March
3d and after January 19th, the last date at which he wrote to his
parents, and as if in a dream, he is now living another life. The
hospital staff generally believe that the man is not "shamming," as
many circumstances seem to preclude that theory. His memory is perfect
as to everything back to March 3d. The theory of hypnotism was advanced
in explanation of this case.

The morbid sympathy of twin brothers, illustrated in Dumas's "Corsican
Brothers," has been discussed by Sedgwick, Elliotson, Trousseau,
Laycock, Cagentre, and others. Marshall Hall relates what would seem to
verify the Corsican myth, the history of twin brothers nine months of
age, who always became simultaneously affected with restlessness,
whooping and crowing in breathing three weeks previous to simultaneous
convulsions, etc. Rush describes a case of twin brothers dwelling in
entirely different places, who had the same impulse at the same time,
and who eventually committed suicide synchronously. Baunir describes a
similar development of suicidal tendency in twin brothers. A peculiar
case of this kind was that of the twin brothers Laustand who were
nurses in a hospital at Bordeaux; they invariably became ill at the
same time, and suffered cataract of the lens together.

Automatism has been noticed as a sequel to cranial injuries, and Huxley
quotes a remarkable case reported by Mesnet. The patient was a young
man whose parietal bone was partially destroyed by a ball. He exhibited
signs of hemiplegia on the right side, but these soon disappeared and
he became subject to periodic attacks lasting from twenty-four to
forty-eight hours, during which he was a mere automaton. In these
attacks he walked continually, incessantly moving his jaw, but not
uttering a word. He was insensible to pain, electric shock, or
pin-prick. If a pen was placed in his hand he would write a good
letter, speaking sensibly about current topics. When a cigarette-paper
was placed in his hand he sought his tobacco box, and adroitly rolled a
cigarette and lighted it. If the light went out he procured another,
but would not allow another to substitute a match. He allowed his
mustache to be burned without resistance, but would not allow a light
to be presented to him. If chopped charpie was put i
