    Ferier s Improvements in the Construction of Vapour and Hot-air Baths. of the several apparatus, and with respect to the materials of which such apparatus are to be made, no positive rule can be given, but the same will be selected at the convenience and discretion of the manufacturer the appa¬ ratus, provided they are of a kind to economise heat and resist the act:on of the vapours, acids, and other matters to which they are intended to be 5 exposed. Having dow described the said improvements in the construction of vapour and hot-air baths, and the manner of applying such baths, I do hereby declare that under the said Letters Patent, herein-before in part recited, I claim the application to the construction of vapour baths of a vessel, such as 10 the vessel E, herein-before described, in which a boiler or generator and flues surrounding it are combined in one vessel, and in which the same passages serve to convey the vapour from the boiler or generator and the heated air from the flues. I claim further the application to the construction of vapour baths of a 15 perforated footstool adapted, as herein-before described, to receive vapour from the generator, and to distribute such vapour to the feet and legs of the patient. I claim the application to the construction of hot-air baths of a lamp to heat a body of air in a hollow vessel placed over such lamp in the manner 20 described in reference to Figure 10, Sheet 2. And I claim, lastly, as applied to the construction of vapour and hot-air baths, the method, which I have herein-before described, of combining appa¬ ratus of any known kind used for obtaining different kinds of chemical vapours possessing the properties herein-before alluded to with the vapour and hot-air 25 baths herein-before described in reference to Sheets 1 and 2; and, save as aforesaid, I do not claim any of the things, apparatus, or modes of operating herein-before described. In witness whereof, I, the said Pierre Jacques Ferier, have hereunto set my hand and seal, the Thirty-first day of January, in the year of our 30 Lord One thousand eight hundred and forty. PIERRE JACQUES (l.s.) FERIER. Signed, sealed, and delivered by the within- named Pierre Jacques Ferier, in the presence of 35 Thomas Dry, 21, Lincoln’s Inn Fields, Solr,
