The inhaler devised by John Mudge,* the type ofmost modern inhalers, consists of a pewter mug (Fig. 1)of the capacity of a quart, with a hollow handle. Theinterior of the handle communicates below with the in-terior of the vessel, and a number of perforations in theupper part of the handle permit the ingress of the exter-nal air during inspiration through the apparatus. Atightly fitting lid of some thickness covers the mug. Acentral perforation in this lid permits the attachment ofa flexible tube through which the patient is to inhale; * A Radical and Expeditious Cure for a Recent CatarrhousCough, etc., London, 1778. 20 THE INHALATION OF while a second perforation incloses a ball-valve of cork,so placed as to permit the egress of air, but prevent itsingress.

The mug being filled to two-thirds of its capacity, thewater of course rises in the handle to the same level;and, therefore, when the patient inspires through theflexible tube, the air rushes through the handle of themug into the water, and out through the the patient expires through the tube, the air ofexpiration passes into the free space beneath the cover,and is expelled out of the second perforation in theeover, lifting the cork-valve in its egress.
