These topical applications are employed chiefly in thermal stationswhere there are gases such as sulphureted hydrogen, carbonic acid, 120 MOUEE—DISEASES OF THE NASO-PHAEYNX AND PHAEYNX. etc., given off from the mineral waters. It is necessary also that thetemperature of the water should be sufficient to volatilize the gaseousprinciples and saturate the air to be inhaled. Some of the spas inFrance are admirably adapted to this purpose. In other cases certain volatile substances such as menthol, thymol, balsam of Peru, eucalyptol, etc., are employed in this manner. Thesevarious medicaments are usually dissolved inalcohol so that their dosage may be properlygraduated, and are then dropped into hot. %> water so as to impregnate the airsurrounding them. We have em-ployed for several years the appa-ratus here illustrated, which byreason of the mask with which it isprovided permits of the passage ofthe impregnated air through thenose into the naso-pharynx or di-rectly into the pharynx itself. 4.
