The mass of material, however, is increased 22 percent. The gas, upon reaching this part of the regenerator, has givenup much of its heat; but as the absorbing mass has been increased,and the gas subdivided into four parts, and brought into contact withnearly double the heating-surface, a greater proportion of the heat ishere taken up from the escaping gases. This reduction of area hasa tendency to increase the loss of head due to friction, but the fluesin the lower part of the regeneratorhave been increased in arraoverthe usual amount, thus compensating for the loss. The stove shown in Figs. 1 and 2 is divided into three passes,increasing the area of each very considerably, and consequently per-mitting a much greater volume of gas to be passed through them ina give
