e the same complaints, and
they come of their own accord to the physician, with an urgent
request to be liberated. I have seen this strange thing occur, even
when they were some miles apart, the one being at Bicetre, and the
other living at Saint-Anne."

I sent a copy of this passage to the principal authorities among the
physicians to the insane in England, asking if they had ever
witnessed any similar case. In reply, I have received three
noteworthy instances, but none to be compared in their exact
parallelism with that just given. The details of these three cases
are painful, and it is not necessary to my general purpose that I
should further allude to them.

There is another curious French case of insanity in twins, which was
pointed out to me by Sir James Paget, described by Dr. Baume in the
_Annales M. edico-Psychologiques_, 4 serie, vol. i., 1863, p. 312,
of which the following is an abstract. The original contains a few
more details, but is too long to quote: Francois and Martin, fifty
years of age, worked as railroad contractors between Quimper and
Chateaulin. Martin had twice slight attacks of insanity. On January 15
a box was robbed in which the twins had deposited their savings. On
the night of January 23-24 both Francois (who lodged at Quimper) and
Martin (who lived with his wife and children at St. Lorette, two
leagues from Quimper) had the same dream at the same hour, three a.m.,
and both awoke with a violent start, calling out, "I have caught the
thief! I have caught the thief! they are doing mischief to my brother!"
They were both of them extremely agitated, and gave way to similar
extravagances, dancing and leaping.

Martin sprang on his grandchild, declaring that he was the thief,
and would have strangled him if he had not been prevented; he then
became steadily worse, complained of violent pains in his head, went
out of doors on some excuse, and tried to drown himself in the river
Steir, but was forcibly stopped by his son, who had watched and
followed him. He was then taken to an asylum by gendarmes, where he
died in three hours. Francois, on his part, calmed down on the
morning of the 24th, and employed the day in inquiring about the
robbery. By a strange chance, he crossed his brother's path at the
moment when the latter was struggling with the gendarmes; then he
himself became maddened, giving way to extravagant gestures and using
incoherent language (similar to that of his brother). He then
