Upon the Destruction of the Puerperal Miasma in Lying-In Hospitals. By Dr. Busch.—The means employed by the author consist in heating the room to a high degree with dry air. This is effected by round iron | stoves placed in the centre of the room, and connected with the chimney by metal tubes. The heat can be raised to 50.60° R. (about 155° F.) This must be kept up for two days, during which time all furniture and utensils are to remain in the room. In March, 1851, puerperal fever invaded the Berlin Lying-in Hospital with remarkable severity; nearly all the patients suffered, and the Insti- tution was closed for six weeks, during which time there was the most careful ventilation and purification. These means proved insufficient. Upon the re-opening of the hospital, all the new patients became attacked by the disease a few days after delivery. Then the author tried the plan here detailed in every room in the house. The effect was surpris- ing; no fresh attack occurred during the whole summer. The same measures were adopted some time afterwards, and with the same success. —London Med. Times, from N. Ztsclir. fur Gebwitsk.
