    Mennons Improved Fumigating Apparatus. Fig 1 : A, pedestal, in iron, brass, copper, or other metal; B, spirit lamp ; C, metallic circle of the support; D, fixed recipient, of metal, glass, porcelain, or other suitable matter, and containing the product to be vaporised ; E, moveable turbine. 5 Fig. 2 is a vertical section of apparatus, Fig. 1. Fig. 3 is another form of the above apparatus, with fixed recipient and moveable turbine. A, pedestal; B, lamp ; C, vertical support of the recipient, secured by the screw a; D, recipient; E, moveable turbine, revolving on the neck of the recipient. 10 Fig. 4 is a horizontal projection of the apparatus, Figure 3. Fig. 5 represents a modification of the apparatus, in which the recipient and turbine follow the same movement of rotation. A, pedestal; B, lamp; C, vertical support of the centre point, on which revolves the recipient; D, revolving recipient, forming part of the turbine ; E, fixed turbine ; F, centre 15 point, on which the apparatus revolves; G, collar, in which revolves the neck of the recipient. The recipient being charged with the substance to be volatilised, and the lamp lighted, the vapour disengaged by the orifices of the turbine produce a movement of rotation, the speed of which is proportioned to the elastic force of 20 the gases evolved, and the diameter of the escape apertures. It is evident that the dispersing or distributing power of the revolving jets is far superior to that of a simple evaporating surface of considerable extent. To this fact is due much of the utility of the apparatus when employed for the volatilisation of perfumes, antiseptics, and medicinal compounds of a certain value, the 25 maximum effect being obtained at the most economical rate possible. When intended for use in purifying the vitiated air of hospitals, lazarettoes, dissecting rooms, barracks, and other establishments exposed to deleterious emanations, the dimensions of the apparatus should be proportioned to the extent of the building or locality to be acted on. For perfuming or disinfecting ordinary 30 appartments, the dimensions given in the Drawing are amply sufficient. The following perfumes and medical compounds may be noted among those advantageously employed with this apparatus:—Alcoholic and other solutions or extracts of aromatic plants and resins, such as rose and lavender waters, tinctures of mint, myrrh, and verbena, eau de cologne, and toilet 35 vinegars, empyreumatic and essentials oils, benzoin, balsams of Tolu, Peru, etc., etc., etc. For hospital, barrack, or prison use, a supply of chlorine may be readily obtained by the decomposition of chloride of lime, muriatic acid with oxide of manganese, or other substances having chlorine for base.
