In 1833 Samuel Lewis stated that "...There are two infirmaries in the prison" - one each for female and male inmates. The 1904 prison inspection describes the "Males' Infirmary" as:

"...entered from the south-end of flat II (second floor) of the Males' cell-block, and is over the Males' reception. There is first a nice "cross-lobby" , in which is a flue for extraction from [a] private clothes-store below, and also the hospital w-c. on the west. Then comes first the Surgery (on left), then a highly ventilated ward for three patients, with clear glass and fan-lights, and a Galton grate in the fireplace. There is a high pressure boiler behind the grate, for the bath. There is also a smaller ward (used as a store), and at the back of all, the good fire-clay bath stands at the south end of this clean and bright sunny passage."
