It was enacted that if any person while in prison under sentence of death, transportation, or imprisonment, or under a charge of any offence, or for not finding bail, or in consequence of any summary conviction, or under any other civil process, shall appear to be insane, it shall be lawful for two justices to inquire, with the aid of two medical men, as to the insanity of such person; and if it be duly certified by such justices and medical men that he is insane, it shall be lawful for one of the principal Secretaries of State to direct his removal to such county asylum or other proper receptacle as the Secretary of State may judge proper, to remain under confinement until it shall be duly certified by two medical men to the Secretary of State that such person has become of sound mind; whereupon he is authorized, if such person remain subject to be continued in custody, to issue his warrant to the person in whose charge he may be, directing that he shall be removed to the prison from whence he has been taken, or if the period of imprisonment has expired, then he shall be discharged. It was also enacted that when a person charged with misdemeanors is acquitted on the plea of insanity, he shall be kept in strict custody during Her Majesty's pleasure, the jury being required to find specially whether such person was insane at the time of the commission of such offence, and to declare whether such person was acquitted by them on account of such insanity. The Earl of Shaftesbury introduced the subject of the provision for criminal lunatics in the House of Lords in 1852, and moved for an Address to Her Majesty on the expediency of establishing a State Asylum for the care and custody of those who are denominated criminal lunatics. He said that the subject had been never propounded before to them in a specific form, and the custody of these criminals had been a great bar to the improvement of public and private asylums. The Commissioners had already reported on these evils in 1849, 1850, and 1851. The Government alone had refused assistance. Having pointed out the four classes into which they are divided, he stated that the statutes by which they were confined were three in number, namely, 39 and 40 Geo. III., c. 94; 1 and 2 Vict., c. 14; 3 and 4 Vict., c. 54.
