The family of the condemned man would usually try to get the body back as soon as possible, since in some cases it was possible to revive a hanged man. In any case, there remained a strong belief that in order to stand a chance of redemption, a corpse should be left intact. Dissection was equivalent to damnation.The family of the condemned man would usually try to get the body back as soon as possible, since in some cases it was possible to revive a hanged man.

Surgery in the Nineteenth Century In the 19th century surgery was greatly improved by the discovery of Anaesthetics.In the 19th century surgery was greatly improved by the discovery of Anaesthetics. As early as 1799 the inventor Humphrey Davy ( ) realised that inhaling ether relieved pain. Unfortunately decades passed before it was actually used.As early as 1799 the inventor Humphrey Davy ( ) realised that inhaling ether relieved pain.
