There has already been, amongst the same prison <p 257>experts, a certain retrogressive movement in regard to isolation. Absolute and continued isolation, indeed, both by day and by night (``solitary confinement'') was at first recommended, even to the introduction, grotesque in spite of good intentions, of hoods and masks for the prisoners, a medi<ae>val reminiscence almost parallel with the Brothers of Pity in some Italian towns, for help to the wounded. Presently it was seen that this sort of thing certainly could not assist in the amendment of the guilty, and then isolation was relaxed (still making it applicable both by day and by night) with visits to prisoners by the chaplain, governors, and representatives of vigilance and prisoners' aid societies. This is called ``separate confinement.'' After this it was recognised that the real need for isolation was at night, and then the Auburn system was arrived at: isolation in cells by night, with daily labour in common, with an obligation (which cannot be enforced) of silence. And finally, seeing that in spite of the threefold panacea of every prison system (isolation, work, and instruction, especially religious instruction) relapses still increased, it was understood that it might not be very useful to subject a man for months or years to the monastic life of Trappist brothers, in these monstrous human hives (which Bentham brought to the notice of the French Constituent Assembly under the name of ``panopticons''), and to discharge him from prison at the end of his term, and plunge him into all the temptations of an atmosphere to which his lungs had become disaccustomed.
