itchell illustrated his paper by examples, two of which will be
quoted. The first was the case of Mary Reynolds who, when eighteen
years of age, became subject to hysteric attacks, and on one occasion
she continued blind and deaf for a period of five or six weeks. Her
hearing returned suddenly, and her sight gradually. About three months
afterward she was discovered in a profound sleep. Her memory had fled,
and she was apparently a new-born individual. When she awoke it became
apparent that she had totally forgotten her previous existence, her
parents, her country, and the house where she lived. She might be
compared to an immature child. It was necessary to recommence her
education. She was taught to write, and wrote from right to left, as in
the Semitic languages. She had only five or six words at her
command--mere reflexes of articulation which were to her devoid of
meaning. The labor of re-education, conducted methodically, lasted from
seven to eight weeks. Her character had experienced as great a change
as her memory; timid to excess in the first state, she became gay,
unreserved, boisterous, daring, even to rashness. She strolled through
the woods and the mountains, attracted by the dangers of the wild
country in which she lived. Then she had a fresh attack of sleep, and
returned to her first condition; she recalled all the memories and
again assumed a melancholy character, which seemed to be aggravated. No
conscious memory of the second state existed. A new attack brought back
the second state, with the phenomenon of consciousness which
accompanied it the first time. The patient passed successively a great
many times from one of these states to the other. These repeated
changes stretched over a period of sixteen years. At the end of that
time the variations ceased. The patient was then thirty-six years of
age; she lived in a mixed state, but more closely resembling the second
than the first; her character was neither sad nor boisterous, but more
reasonable. She died at the age of sixty-five years.

The second case was that of an itinerant Methodist minister named
Bourne, living in Rhode Island, who one day left his home and found
himself, or rather his second self, in Norristown, Pennsylvania. Having
a little money, he bought a small stock in trade, and instead of being
a minister of the gospel under the Methodist persuasion, he kept a
candy shop under the name of A. J. Brown, paid his rent regularly, and
acted
