    JunocTs Impts. in Vacuum Apparatus for the Relief of Inflammatory Diseases^ the joint where the two parts are connected, and are rendered air-tight by an india-rubber bracelet or collar fastened to one of the parts. The third part of my improvements relates to vacuum apparatus applicable to the leg of a patient. The india-rubber “ muff” or sleeve hitherto employed for connecting the instrument to the limb was so stout as frequently to cause 5 pain to the patient, but if not of sufficient strength^ is liable to burst when in use, and in order to obviate this injury and expense I employ a “ muff*’ or sleeve of silk or other woven fabric as an inner muff to be used in com¬ bination with a sleeve or muff of thin and soft india-rubber as may be desired ; the inner muff of silk or other fabric imparting sufficient strength to the 10 india-rubber, and preventing pain from too great pressure caused by using stout india-rubber as heretofore employed. Figure 2 shows an improved muff, which overcomes the difficulty which has hitherto prevented the use of this apparatus. The india-rubber may be also protected from bursting inwards by a collar of metal or other material of 15 sufficient strength, such collars in some cases being capable of expanding in order to adapt them to limbs of different size; or the metal collars may be made in two parts, and be connected together upon the limb by means of a sliding bolt 5, 5, as shown in Figures 3 and 3^, or other suitable fastening. Figure 3 shows vacuum apparatus for the leg constructed in accordance with 20 this part of my improvements. The large or small opening (1, Figure 2) of the muff is applied according to the size of the limb of the patient, the other opening being connected with the apparatus,'so that the same muff will fit all sizes. Between the cloth muff and the india-rubber muff a pillow is formed around the limb of wool or other soft material to prevent any painful ^5 pressure from the muff. Much difficulty has been experienced in adapting vacuum apparatus of this character to the legs of different patients owing to the varying dimensions of the limbs, and this part of my improvements consists in the application of a collar to the top of the apparatus so as to adapt the instrument to legs of 30 large or small circumference without inconvenience to the patient. A similar adjusting ring or collar may be used in combination with vacuum apparatus applied to the arm. Apparatus of this character may be constructed suitable for being applied to part only of the arm, leg, or thigh of a patient, leaving the hand, foot, or other parts exposed. 35 _ s The fourth part of my improvements consists in forming vacuum apparatus for the leg or arm in several parts or sections, and in connecting them in the manner herein-before described, by which means they may be packed within each other so as to occupy but little space. This improvement admits of the
