I direct that an ordinary clothes-basket 24 inches long be procured. This can be purchased in any village. The bottom is padded so that the basket has a depth of 8 inches. It is then lined with white oilcloth and over this a layer of cotton batting held in place by being stitched through the sides of the basket. This in turn is covered with white flannel.
Heat is maintained by means of hot-water bottles.
I always direct that these be covered by flannel. The 12-ounce citrate of magnesia bottle is convenient, as it has a rubber cork and a wire fastener that insures against leaking. Five of these bottles are sufficient to maintain proper temperature. A thermometer is kept in the basket and the heat maintained at from 90 to 95 degrees. During the night when the room temperature is lower it may be necessary to cover the basket with a rubber sheet in order to maintain the temperature.
