Descriptions
'These lock-ups are under the Sessions-house, and are principally made use of for the detention of prisoners during the sessions. They were clean; but accommodation for the male prisoners is very defective, the cells being dark, ill-ventilated, and quite inappropriate for men about to undergo the ordeal of a public trial.'
Inspectors of Prisons of Great Britain II. Northern and Eastern District, Eighth Report (Parl. Papers, 1843, XXV. & XXVI.249), p.148
'These lock-ups are under the sessions house. They are dark, damp and deficient in ventilation. To these wretched places are prisoners conveyed to await their trials in the court above, and are frequently detained in them for a night, and sometimes more. They are unfit for the confinement of any description of prisoners, and least of all for those about to undergo the ordeal of a public trial, where the offences and consequences are so serious.'
Inspectors of Prisons of Great Britain II. Northern and Eastern District, Fourth Report (Parl. Papers, 1839, XXII.1), p.142
