P, Figure 4, is a plan of a cast-iron carriage. Figure 3 represents a side elevation of a carriage, with two sets of cast-iron 15 or earth pots filled with charcoal, prepared as herein-before described, and placed on the carriage ready to be introduced into the retort. The advantages and result obtained by this furnace are, firstly, to prevent the pots containing the moulded charcoal coming in contact with the flame during the operation of carbonising, to preserve them from a two rapid de- 20 struction, which is the natural consequence of all other systems. Secondly, to employ no other combustible than that given out by the gases submitted to carbonisation. Thirdly, to maintain the furnace at an equal and continual temperature during the whole of the operation. Fourthly, to burn infectious gases, and, in this respect, to solve one of the most important problems of 25 public health. Fifthly, to prevent the workmen from entering into the furnace when it is heated to take out the pots, and to render their work more healthy and less difficult. Sixthly, to add to the fabrication a great rapidity of operation, with a very important economy. The working of this improved furnace is carried on as follows :—The pots 30 filled with the moulded charcoal are placed upon the carriages, two of which loaded with pots are introduced into each retort by means of rails. The doors H, H, of the retorts are hermetically closed by carefully luting them air-tight. The fire of the hearth N, by introducing itself into the space F, left vacant between the retorts, warms them, and causes the evaporation of the gases 35 which escape from the pots, and the fire only lights after their exit from the retorts by the ventilating holes E. By these means the flame is entirely separated from the pots ; when the retorts are hot enough, and the gases escape in sufficient quantity to maintain the furnace at the necessary heat, the
