If an offender has been convicted and sentenced according to law, he must be regarded and received into the cell as a suitable subject of convict-discipline. A process of law so terminated, is tantamount to incontrovertible evidence, that the party is in all respects amenable to the penal sanctions of the law. Otherwise he is not a convict, but an oppressed and abused sufferer. Having thus been committed, he must abide the life of a convict. If his health fails, humane provision should be made for him in a proper apartment, called an infirmary or hospital, with proper attendance, medicine, nourishment, &c., but why should he be pardoned, removed or discharged? Sickness in prison is one of the risks he voluntarily takes in committing the offence. If he breaks a limb or loses an eye, it is what happens to honest men as well as convicts, and he can claim no exemption from such calamities, and must be satisfied with prison fare when they overtake him as a convict. Why should the failure or loss of mental soundness be a cause of discharging a prisoner, any more than the weakness or maiming of the body? Why should not provision be made within the prison-bounds for the proper care and treatment of this class of ailments, as well as any other? Certainly not because it is not practicable to do it, for the medical records show that the recoveries among convict-lunatics here and in England, bear quite as high a proportion to the cases, as in our best Insane Asylums. If it should be maintained that the proper room and attendance cannot be obtained, the same reason might be urged for discharging the sick and lame, that there was no room for an infirmary, nor for surgical operations, nor for nurses, &c. We do not see what reasonable ground can be urged for the removal of the former, which might not be quite as tenable in relation to the latter. It seems to us that when the Commonwealth, whose peace and dignity have been violated by a breach of the law, seizes on the offender, and separates him from honest citizens, clearly proves his guilt, and commits him for punishment to hard labor in the penitentiary for a term of months or years, nothing should avail to discharge him from that sentence, except the discovery of some evidence of its injustice. It is assumed, of course, that he has been legally and fairly dealt with in the whole process of the prosecution, and that the sentence is as light as the law or the circumstances of the case will justify; and this being conceded, we confidently maintain that the State takes him into her custody as a convict, and that, as a convict she is bound to provide for him whatever he needs, whether in health or sickness, in strength or weakness, in life or death, until he has accomplished his full term. We venture to make these suggestions the more plainly, because we perceive not a little confusion in the views which are gaining ground on the subject.
