" The building circular – A cage, glazed – a glass lantern about the Size of Ranelagh – The prisoners in their cells, occupying the circumference – The officers in the centre. By blinds and other contrivances, the inspectors concealed - from the observation of the prisoners: hence the sentiment of a sort of omnipresence – The whole circuit reviewable with little, or if necessary without any, change of place. One station in the inspection part affording the most perfect view of every cell. " [1]
