But then it is essen- tial that the heat be so equally distri- buted as to avoid heating any portion of the cotton to such a degree as to destroy its physical properties. This uniformity of heat is provided for by having three shelves of sheet iron inter- posed between the large Bunsen’s burner and the bottom of the box, so as to prevent the heat from acting directly upon it, while at the Fig. 4.—Door of Mr. Lister’s box.
