rpse of his brother, but he died on the third
day after the operation.

In 1866 Boehm gives an account of Guzenhausen's case of twins who were
united sternum to sternum. An operation for separation was performed
without accident, but one of the children, already very feeble, died
three days after; the other survived. The last attempt at an operation
like this was in 1881, when Biaudet and Buginon attempted to separate
conjoined sisters (Marie-Adele) born in Switzerland on June 26th.
Unhappily, they were very feeble and life was despaired of when the
operation was performed, on October 29th. Adele died six hours
afterward, and Marie died of peritonitis on the next day.

CLASS III.--Those monsters joined by a fusion of some of the cranial
bones are sometimes called craniopagi. A very ancient observation of
this kind is cited by Geoffroy-Saint-Hilaire. These two girls were
born in 1495, and lived to be ten years old. They were normal in every
respect, except that they were joined at the forehead, causing them to
stand face to face and belly to belly. When one walked forward, the
other was compelled to walk backward; their noses almost touched, and
their eyes were directed laterally. At the death of one an attempt to
separate the other from the cadaver was made, but it was unsuccessful,
the second soon dying; the operation necessitated opening the cranium
and parting the meninges. Bateman said that in 1501 there was living an
instance of double female twins, joined at the forehead. This case was
said to have been caused in the following manner: Two women, one of
whom was pregnant with the twins at the time, were engaged in an
earnest conversation, when a third, coming up behind them, knocked
their heads together with a sharp blow. Bateman describes the death of
one of the twins and its excision from the other, who died
subsequently, evidently of septic infection. There is a possibility
that this is merely a duplication of the account of the preceding case
with a slight anachronism as to the time of death.

At a foundling hospital in St. Petersburg there were born two living
girls, in good health, joined by the heads. They were so united that
the nose of one, if prolonged, would strike the ear of the other; they
had perfectly independent existences, but their vascular systems had
evident connection.

Through extra mobility of their necks they could really lie in a
straight line, one sleeping on the side and the other o
