$force that the ordinary strength of an inspiratory eifort cannot deflect it into the air-passages, and the greater part of it condenses upon the pharynx and soft palate, and sometimes strikes these parts with such force (ac- cording to Lewin) as to cause spasmodic closure of the glottis and excite spasms of coughing. It is but fair to mention that this instrument was originally intended for administering a spray bath to any individual por- tion of the body. [See G-az. Hehdom.^ May 4,1860, and \_Matthieus letter] May 11, 1860.) Lambron, Yelpeau, and others have constructed sim- ilar instruments on the same principle. {Lewin?) Sales-Girons also constructed a third instrument, in which the spray is produced by the agency of bristles attached to the circumference of a wheel. As the wheel is rapidly turned, the brushes dip into the fluid to be nebulized, and as they emerge from it strike with force against a ledge, and thence the fluid is disseminated as a fine spray. [Fieher.) Lewin, of Berlin, has constructed an apparatus with an ordinary suction pump (syringe) which forces the liquid into a reservoir, the air within which is thus com- pressed, and in its turn becomes a propelling force driving the fluid, by the opening of a valve, out of a very fine aperture, whence it impinges on a convex button, and is thus broken into spray. This apparatus once set in action will continue to work for a consider- able time without further pumping. Waldenburg (Die Inhalationen der zerstaubten FKlssigkeiten, &c., von Dr. L. Waldenburg, Berlin, 1864), has constructed an apparatus with a suction and forcing pump (the same sort of pump that is furnished with Mayer's uterus douche), which draws the liquid$
