    Rumseys Improvements in Boilers for Distillation, Steam Engines, §c. will prevent them from wearing or shocking the vessels which contain them when shutg, and likewise enable them, in some degree, in some cases to act like the air vessel here mentioned. As my boilers, steam vessels, or stills may be infinitely varied in their forms and applications, it is impossible to give Drawings 5 of them all, but those that follow will sufficiently explain the nature of the principles I have laid down. Fig. 1 represents a boiler composed of tubes, the open ends of which are inserted into the upright side of a metal box. It is to be surrounded with a case of a somewhat larger size, seen at Fig. 2. The fluid or vapor is heated 10 both in the tubes and between the box and its case. The fire-place is within the box, and its flame, &c. presses round the tubes, but so as that its course tends first upwards by means of a partition within the box lying parallel to the dotted line C, and then downwards on the other side of the partition at C to get at the passage to the chimney of Fig. 2, placed at the bottom. Fig. 3 15 represents tubes and other inclosures for fluid and vapor. The tubes do not reach entirely through this vessel, as in the preceding instance, but point towards the fire from each side, and stop on each side at the fire, being closed at that part towards the fire, though open outwards, as in the preceding instance. There is a similar outward case to the whole, as in Fig. 2, for a similar purpose. 20 Fig. 4 represents one of the two plates to be inserted within the vessel at Fig. 3 on each side of its fire-place B. The flat prongs of these plates, passing at right angles into the hollows of the upper inclosures (which are white in the Drawing) fit the hollows closely except at the tops, by which means the heat, &c. rises upright in the middle, but descends to the right and left over the tops 25 of the flat prongs, and when descended goes by a passage to the chimney, as in the former instance. The black parts seen laterally in Fig. 3 contain fluid and steam. The lower parts of the plates represented at Fig. 4 may or may not have perforations for the heat to get at the tubes. In both the preceding cases the chimney is made with a double flue, between which fluid to feed the boiler 30 descends to obtain a previous heat. It is needless to shew how the vapor is drawn off. A, B, (Fig. 5,) is the section of an outside case to another boiler; the fire is enclosed at C, D, and sends its heat through tubes, the open ends of which are fastened into places at E and G. The interstices of the tubes are filled with fluid which communicates with other fluid in the outside case, as in 35 the preceding instances. The tube and cap H and F being let down to close upon the plate E, causes the smoak to rise through the flue H; the fluid floods over the cap, but does not ascend to the top of the outside case A, B, a part of its vault being left for vapour. A, B, (Fig. 6,) is another section of an outside case, and E and E are each respectively double plated cylinders, which stop
