    De Chabannes Impts. in Warming, Cooling, and Conducting Air in Homes, cj-c. warm air bath, in which the temperature may be raised to a degree of heat which vapour and steam would not admit of without affecting the skin of the patient. The warm air bath may be used as a means of administering remedies thro’ the pores, which the state of the stomach will not permit to 5 be administered internally. And, 4tllly, for warming air by steam, I make use of cylinders or boxes containing a number of air pipes, which present a larger surface to the contact of caloric than the double cylinder in present use. See Plate 2, Fig. 4; (a), cylinder or box into which the steam is introduced; (6), air pipes. Another part of my improvements in conducting of air is by 10 placing what I denominate an air purifier at the place where the cold air enters; this purifier is composed of a box containing several slides of wire- work, each finer than the other, the bottom having the largest openings, by which means the air deposits in its passage thro’ them the greatest part of the particles of dust with which it is loaded; see Plate 2, Fig. 3; (a), box with 15 three slides; (b), one of the slides. My improvements upon warming liquids are applicable to boilers of every description; I place a tube attached to the upper part of the boiler, into which the more rarefied water will ascend, and carry this tube to any distance, according to the purpose intended, and return it at the lower part of the boiler, as seen in Plate 3, Fig. 1; (a), boiler; 20 (A), tube by which the water ascends; (c), tube communicating with the bottom of the boiler at one end and with the tube (b) at the other, by which, after the water has been conducted to the parts wanted, it returns to the boiler, thereby producing a continual circulation of water thro’ the boiler and the various apparatus for different purposes which may be connected with it; 25 the idea of this part of my improvements is what was communicated to me from abroad, but which I have subsequently improved in a very considerable degree by my own experiments. Also to heating a greater quantity of liquid from the same fire, and procuring from it a power of steam for other purposes, I make use of the said boiler and tubes, and cause the upper tube, into which 30 the rarefied water ascends, to communicate with a main tube or cylinder above, and connected with a number of additional boilers, either of the same or different shapes, and these boilers being joined to a main tube or cylinder below, from whence the tube or the continuation of the tube originally issuing from the upper part of the main boiler, is returned to the lower part, as before 35 described, for the purpose of effecting a constant circulation of water tliro' the boiler immediately in contact with the fire and the different apparatus which are or may be connected to it, Plate 3, Fig. 2 : (a), pipe communicating from the top cylinder to the boiler; (&), five separate boilers, on the entire circum¬ ference of which the flame and smoke act, and connected to the top cylinder
