Excerpt from The Diffusion of Oxygen Through Stored Coal
The chamber may be considered divided into three compartments, placed one above the other. Details of the lower compartment and of the coal compartment are given in figure 1, in which ca, and a, represent tubes opening into the interior, a, and at, being closed with rubber stoppers. Through a, was run a capillary tube 6, from the center of the lower compartment to the gas-sampling apparatus. The coal was supported by a stiff steel-wire net, d, of -in0h mesh, resting on the lugs e and 0. When coal finer than g-inch mesh was used a fine wire gauze was laid over the net.
