    Mattsons Improved Apparatus for Administering Injections, The naso-phargngical irrigator, Pigures 5 and 6, is a hollow tube, six inches long, made of metal or hard rubber. The terminal extremity, shewn at is turned up, as shewn in Figure 5, about of an inch; m is a screw coupling. The orifice n, through which the fluid escapes, is at a right angle to the tube ; it is a fine slit about of an inch 5 in length. This tube, connected with the apparatus. Figure 1, or any suitable syringe, when introduced carefully behind the uvula and soft palate, is very useful. In some cases it may be used for projecting a stream of fluid simultaneously through the nostrils. The improved box. Figure 7, is provided ydth a tray o, and, as above 10 specified, is designed to keep the injecting tubes and other parts in place, and prevent their shaking and rattling in the box. This tray may be made of wood or other suitable material. It is placed in the top of the box, resting upon wooden supports ; it has a central opening^, through which the bulb or bottle a projects when properly adjusted or packed 15 within the box. The injecting tubes, and other parts, are placed in grooves or u’eceptacles upon the top of the tray o, and are safely secured when the lid of the box is closed. In witness whereof, I, the said Morris Mattson, have hereunto set my hand and seal, this Third day of January, in the year 20 of our Lord One thousand eight hundred and seventy-three.
