    JEstor 8f JPearce’s Improvements in Disinfecting or Deodorizing. A, A, the cup or vase formed of burnt pipeclay, glass, porcelain, enamelled metal, or prepared wood; B, B, pedestal upon which the vase stands ; C, C, disinfecting composition, consisting of chloride of lime (or other earths or salts holding or containing chlorine) and a solution of sulphate of iron (or other sulphates) in suitable proportions for forming 5 a stiff compost; D, D, external combustible coating composed of an inner layer of finely divided charcoal intimately mixed with gelatinous or mucilaginous substances aforesaid, upon which an outer surface of sublimed, powdered, or liquid sulphur is applied; E, E, cap of thin india-rubber, gutta percha, or other prepared substances, for hermetically 10 sealing or closing the contents of the cup; E, E, inflammable band, string, or ribbon (prepared with a solution of collodion and gumbenzoin, or other ignitable ingredients) surrounding the neck or lower portion of the vase in contact with the combustible coating, by which the same is lighted through the medium of a match or taper G, G, as shown at 15 Eig. 4; H, II, box or wrapper enclosing the cup or vase in which the same is commercially vended ; I, I, lid of same. In addition to the above a capsule of glass, membrane paper, or porcelain clay, sealed or luted down, is also employed for containing and doubly protecting the disinfecting composition enclosed within 20 the cup. In putting the disinfecting cup into operation, the thin india-rubber cap E is first removed, the capsule is next broken, and the light applied to the combustible ribbon E, whereby the external coating of sulphur and charcoal aforesaid is ignited, and sulphurous acid gas given off in 25 conjunction with the chlorine liberated from the internal compost by means of the heat communicated thereto. In conclusion to the foregoing description, we would here briefly note that we are aware that chlorine and sulphur have before been separately used for disinfecting purposes, but hitherto independently of any 30 systematic order or combination of ingredients as employed by us. And we would further note that in cases where chlorine is objection¬ able, as in a sick room, the sulphur cup can be used independently of the internal compost. Having now fully described and ascertained the nature of this our said 35 Invention, and the manner in which the same is to be performed and carried into effect, we would have it clearly understood that we do not intend to confine ourselves to the precise details herein-before set forth
