The best ventilation is from opposite windows. Each window should be in three parts, the third or uppermost to consist of a flap hung on hinges to open inwards and throw the air from without upwards. Inlet valves, to admit fresh air, and outlet shafts, to emit foul air, must be added to complete the natural ventilation. 10. _Furniture, Bedding, Linen._ As little ward furniture as possible. As much clean linen as possible. A very large and convenient clean linen-store, light and dry, must be assigned to the matron: very much larger than would be required for a general hospital; but no general hospital in London supplies a good standard for such. There must be in each scullery, besides, a clean linen-press. There should be a very ample and convenient place for bedding. Mattresses, blankets and the like, have to be renewed, taken to pieces and washed—especially those used in the delivery ward—many times oftener than in any general hospital. The rack for linen should be along the middle of the linen-store. There should be space for a bedding-rack along one end, taking about three feet six inches from the length of the room for linen. Space for some spare mattresses and bolsters will be necessary; and they should be stowed near to a lift. A linen-store requires thorough lighting, ventilating, and warming. Three windows are better than one. The linen must of course be kept dry and aired. 11. _Water Supply, Drainage, Washing._ Unlimited hot and cold water supply, day and night, should be laid on all over the buildings. All drains and sewers must be kept outside the walls of the buildings, and great care should be bestowed on trapping and ventilating them, to prevent foul air passing into the institution. The washing in a lying-in institution is, it need not be said, very large, and should be conducted quite at a distance. Sink-baths, for immediately putting in water soiled linen, are necessary. 12. _Medical Officer’s Room and Waiting-room._ No dispensary, especially no dispenser, is needed in a lying-in institution. A medical officer’s room is necessary. The medical officer is not resident. He makes his morning and evening visit, and is called in by the head midwife for any difficult case. He gives instruction, scientific and practical, to the pupil midwives. [These lectures are given in the pupil midwives’ mess-room.] In the medical officer’s room should be kept the instruments, to which a fully qualified head midwife also has a key. The medical officer keeps the notes of cases, &c., and of instruction to the pupil midwives in this room. The few, very few, drugs needed in a good lying-in institution are kept here, or in the head midwife’s sitting-room. A waiting-room is necessary. There must be a room where the head midwife can examine a woman, to know if labour is imminent. This might be done in the medical officer’s room or the waiting-room.
