    BellforcVs Improvements in Apparatus for Inhaling Iodine. is covered with a metallic substance E, f throughout the whole space submitted to the action of the flame, in order to preserve the glass and diffuse the temperature. 2nd, of a spirit lamp, which is composed, first, of the space A, 5 which receives the spirit; second, with a cap G, air tight to prevent the evaporation of the liquid, when the apparatus is not to be used; third, of a glass wick holder G ; fourth, laterally, is a metallic arm H, at the extremity of which is a collar S, disposed in such a manner as to maintain the inhaling apparatus in a convenient 10 position; fifth, of a metallic stem B, which on one part supports all these pieces, and is screwed to a metal stand (7. By means of this disposition the air enters by the orifice /, and is raised to a high temperature in passing through the space E, /, and in this state it is charged with a greater quantity of iodine in the state of 15 vapour. The iodine is preserved in cylinders in small tubes Fig, 5, fixed by one end to the lamp and at the other by an air-tight stopper. To construct this flask tubes are used whose smallest diameter is such as to allow the cylinders to slide easily without shaking, which 20 preserves them from injury. These tubes or flasks have another advantage, that of permitting the introduction of the iodine into the apparatus with the greatest facility, merely by opening each ap¬ paratus, and placing the orifice of the flask in such a manner that by a slight inclination the cylinder will slide into the space reserved 25 for it. These first two forms of apparatus which are described are in¬ tended in case one has at disposal iodine weighed and moulded by the process hereafter described. Figs. 3 & 4, represent apparatus by which, with common iodine, the quantity absorbed may be known 30 by observing the decrease of the weight. This apparatus is represented the full size. It is composed principally of a small measure very susceptible, indicating immediately the quantity of iodine which it contains. The tapering extremity of the tube C, terminates by a small opening o} permitting only the passage of the rod to which 35 is suspended, by the hook m} the basket n} which receives the iodine?
