    Feriers Improvements in the Construction of Vapour and Hot-aii Faths. the apparatus will of course for that purpose be provided with additional lengths of pipe g9 If, instead of mixing the sulphurous acid gas with the vapour of water it is desired to take a bath composed of sulphurous acid gas mixed with dry hot air, then such compound hot-air bath will be composed of a combination of the apparatus, Figure 1, Sheet 3, with the apparatus, 5 Figure 10, Sheet 2. For this purpose the pipe g. Figure 1, Sheet 3, is replaced by a pipe j, Figure 3, and that pipe j is laid direct into the bed of the patient side by side with the conducting pipe X of the hot-air bath, Figure 10, Sheet 2. To take a bath of sulphurous acid gas sitting, whether in combination with hot air or with the vapour of water, the tube K, 10 Figure 4, Sheet 3, is fitted on to the apparatus B 2, Figure 1, instead of the tube g, and that tube K being introduced under the covering which sur¬ rounds the patient will deliver its stream of gas to mix with the vapour or hot air which the patient is taking from one or other of the apparatus, Sheets 1 and 2. m is a staple, which may be screwed to the floor to keep 15 the tube K steady. In Figure 5, Sheet 3, I have represented an apparatus to be combined with the vapour bath represented in Figures 1, 2, and 3, Sheet I, for the purpose of producing a compound apparatus for giving a bath of vapour of water and sulphuretted hydrogen combined. The sulphuretted hydrogen may 20 be obtained from such chemical solutions and acids as are usually employed for that purpose by chemists; as, for instance, sulphuret of potassium and acetic acid, or sulphuret of iron and dilute sulphuric acid, the same being introduced and mixing in a glass bottle q, q, as in the ordinary modes of operating to obtain sulphuretted hydrogen. The bottle q is for that purpose 25 provided with a funnel and tubes n and p for introducing the acid used, the tube p passing through a cork s to make gas-tight fitting, and the other matters may be introduced either previously through the opening s, or the bottle may be provided with a second neck tube and funnel for that purpose. As the sulphuretted hydrogen becomes evolved by the action of the chemical 30 agents contained in the bottle q it rises up through the bent pipe r, which is fitted into the bottle q through a cork t, and passes up into the short tube 8 of a tube h adapted to fit the tube 3, 3, of the apparatus, Sheet 1, in the same manner as I have described in reference to Figure 1, Sheet 3, the tube r teiminating at i. The sulphuretted hydrogen thus conducted into the pipe h, 35 mixes therein, on leaving the pipe r, i, with the vapour of water which fills the pipe h, and the two vapours then flow on together into the bed of the patient thiough the continuation of the pipe h, in the same manner as I have described in speaking of the bath of sulphurous acid gas.
