We have no doubt that if the Legislature of this State should undertake to proscribe for any offense against its laws the punishment of burning at the stake, breaking at the wheel, etc., it would be the duty of the courts to pronounce upon such attempt the condemnation of the Constitution. The question now to be answered is whether the legislative act here assailed is subject to the same condemnation. Certainly, it is not so on its face, for, although the mode of death described is conceded to be unusual, there is no common knowledge or consent that it is cruel; it is a question of fact whether an electric current of sufficient intensity and skillfully applied will produce death without unnecessary suffering.
